Overview

本指南向您介绍如何使用 Amazon Web Services (AWS) KMS构建启用了 Queryable Encryption 的应用程序。

在完成本指南中的步骤后，您应该具有：

托管在 AWS KMS 实例上的客户主密钥。
一个有效的客户端应用程序，使用客户主密钥插入加密文档。

开始之前

要完成并运行本指南中的代码，您需要按照安装要求页面所示设立开发环境。

提示

请参阅：完整应用程序

要查看您在本指南中创建的应用程序的完整代码，请选择与您的编程语言相对应的标签页，然后点击提供的链接：

设置 KMS

创建客户主密钥

登录AmazonAmazon Web Services Web Services管理控制台。

导航至Amazon WebAmazon Web ServicesKMS Services KMS控制台。

创建客户主密钥

按照有关创建对称 KMS 密钥的官方 AWS 文档，创建新的对称密钥。您创建的密钥是客户主密钥。选择有助于识别该密钥的名称和描述；这些字段不影响 CMK 功能或配置。

在密钥生成过程的 Usage Permissions步骤中，应用以下默认密钥策略，该策略使身份和访问管理 ( IAM ) 策略能够授予对您的客户主密钥的访问权限：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Enable IAM User Permissions",
      "Effect": "Allow",
      "Principal": {
        "AWS": "<ARN of your AWS account principal>"
      },
      "Action": "kms:*",
      "Resource": "*"
    }
  ]
}

重要

记录您的客户主密钥的 Amazon 资源名称 (ARN) 和区域。您将在本指南的后续步骤中用到它们。

提示

了解详情

要了解有关客户主密钥的更多信息，请参阅密钥和密钥保管库。

要了解有关密钥策略的更多信息，请参阅 AWS 官方文档中的 AWS KMS 中的密钥策略。

创建 AWS IAM 用户

导航至AmazonAmazon Web Services Web Services IAM 控制台。

创建 IAM 用户

按照有关添加用户的官方文档，在管理控制台中创建新的编程 IAM 用户Amazon Web ServicesAmazon Web Services 。您将使用此IAM用户作为启用了Queryable Encryption的应用程序的服务帐户。 Amazon Web ServicesKMS您的应用程序使用 IAM 用户通过进行身份验证，通过客户主密钥(集合扫描) 对数据加密密钥 (DEK) 进行加密和解密。

重要

记录凭证

确保在创建 IAM 用户的最后一步记录以下 IAM 凭证：

访问密钥 ID
秘密访问密钥

您有一次机会记录这些凭证。如果在该步骤中没有记录这些凭证，则必须创建另一个 IAM 用户。

授予权限

向该 IAM 用户授予远程主密钥的 kms:Encrypt 和 kms:Decrypt 权限。

重要

新的客户端IAM用户不应具有主密钥的管理权限。为了确保数据安全，请遵循最小权限原则。

以下内联策略允许 IAM 用户按照最小权限原则使用客户主密钥进行加密和解密：

注意

远程主密钥 ARN

以下策略需要您在本指南的创建主密钥步骤中生成的密钥的 ARN 。

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["kms:Decrypt", "kms:Encrypt"],
      "Resource": "<the Amazon Resource Name (ARN) of your remote master key>"
    }
  ]
}

要将上述政策应用于 IAM 用户，请遵守 AWS 文档中的添加 IAM 身份权限指南。

重要

在生产环境中使用 IAM 角色进行身份验证

将启用了 Queryable Encryption 的应用程序部署到生产环境时，请通过IAM角色而不是IAM用户对应用程序进行身份验证。

要使用IAM角色进行身份验证，请在 KMS 提供商对象中指定临时IAM角色档案，如下所示：

{
    "accessKeyId":"<temporary access key ID>",
    "secretAccessKey":"<temporary secret access key>",
    "sessionToken":"<temporary session token>"
}

您可以通过以下机制获取临时IAM角色档案：

您的应用程序必须包含逻辑，用于获取新的临时凭证，并在每组临时凭证过期时重新创建启用了 Queryable Encryption 的MongoClient实例。

要了解有关 IAM 角色的更多信息，请参阅官方 AWS 文档中的以下页面：

要了解如何获取临时凭证并以本指南支持的每种语言担任角色，请参阅 Amazon Web Services 文档中的以下AssumeRole可运行示例：

Java
NodeJS
Python （示例使用多重身份验证）
C#
Go

创建应用程序

在密钥保管库集合上创建唯一索引

在你的encryption.__keyVaultcollection中的keyAltNames字段上创建唯一索引。

选择与所需的 MongoDB 驱动程序对应的标签页：

make_data_key.js

const uri = "<Your Connection String>";
const keyVaultClient = Mongo(uri);
const keyVaultDB = keyVaultClient.getDB(keyVaultDatabase);
// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.
keyVaultDB.dropDatabase();
keyVaultDB.createCollection(keyVaultCollection);
const keyVaultColl = keyVaultDB.getCollection(keyVaultCollection);
keyVaultColl.createIndex(
  { keyAltNames: 1 },
  {
    unique: true,
    partialFilterExpression: { keyAltNames: { $exists: true } },
  }
);

MakeDataKey.cs

var connectionString = "<Your MongoDB URI>";
var keyVaultNamespace = CollectionNamespace.FromFullName("encryption.__keyVault");
var keyVaultClient = new MongoClient(connectionString);
var indexOptions = new CreateIndexOptions<BsonDocument>
{
    Unique = true,
    PartialFilterExpression = new BsonDocument
        {{"keyAltNames", new BsonDocument {{"$exists", new BsonBoolean(true)}}}}
};
var builder = Builders<BsonDocument>.IndexKeys;
var indexKeysDocument = builder.Ascending("keyAltNames");
var indexModel = new CreateIndexModel<BsonDocument>(indexKeysDocument, indexOptions);
var keyVaultDatabase = keyVaultClient.GetDatabase(keyVaultNamespace.DatabaseNamespace.DatabaseName);
// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.
keyVaultDatabase.DropCollection(keyVaultNamespace.CollectionName);
var keyVaultCollection = keyVaultDatabase.GetCollection<BsonDocument>(keyVaultNamespace.CollectionName);
keyVaultCollection.Indexes.CreateOne(indexModel);

make-data-key.go

uri := "<Your MongoDB URI>"
keyVaultClient, err := mongo.Connect(context.TODO(), options.Client().ApplyURI(uri))
if err != nil {
	return fmt.Errorf("Connect error for regular client: %v", err)
}
defer func() {
	_ = keyVaultClient.Disconnect(context.TODO())
}()
keyVaultDb := "encryption"
keyVaultColl := "__keyVault"
keyVaultNamespace := keyVaultDb + "." + keyVaultColl
keyVaultIndex := mongo.IndexModel{
	Keys: bson.D{{"keyAltNames", 1}},
	Options: options.Index().
		SetUnique(true).
		SetPartialFilterExpression(bson.D{
			{"keyAltNames", bson.D{
				{"$exists", true},
			}},
		}),
}
// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.
if err = keyVaultClient.Database(keyVaultDb).Collection(keyVaultColl).Drop(context.TODO()); err != nil {
	log.Fatalf("Collection.Drop error: %v", err)
}
_, err = keyVaultClient.Database(keyVaultDb).Collection(keyVaultColl).Indexes().CreateOne(context.TODO(), keyVaultIndex)
if err != nil {
	panic(err)

// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.
keyVaultClient.getDatabase(keyVaultDb).getCollection(keyVaultColl).drop();
MongoCollection keyVaultCollection = keyVaultClient.getDatabase(keyVaultDb).getCollection(keyVaultColl);
IndexOptions indexOpts = new IndexOptions().partialFilterExpression(new BsonDocument("keyAltNames", new BsonDocument("$exists", new BsonBoolean(true) ))).unique(true);
keyVaultCollection.createIndex(new BsonDocument("keyAltNames", new BsonInt32(1)), indexOpts);
keyVaultClient.close();

make_data_key.js

const uri = "<Your Connection String>";
const keyVaultClient = new MongoClient(uri);
await keyVaultClient.connect();

connection_string = "<your connection string here>"
key_vault_coll = "__keyVault"
key_vault_db = "encryption"
key_vault_namespace = f"{key_vault_db}.{key_vault_coll}"
key_vault_client = MongoClient(connection_string)
# Drop the Key Vault Collection in case you created this collection
# in a previous run of this application.
key_vault_client.drop_database(key_vault_db)
key_vault_client[key_vault_db][key_vault_coll].create_index(
    [("keyAltNames", ASCENDING)],
    unique=True,
    partialFilterExpression={"keyAltNames": {"$exists": True}},
)

创建你的数据加密密钥和加密collection

添加 AWS KMS 凭证

将服务帐户凭证添加到启用了 Queryable Encryption 的客户端代码中。

选择与所需的 MongoDB 驱动程序对应的标签页：

提示

您在本指南的创建 IAM 用户步骤中创建并记录了访问密钥ID和秘密访问密钥。

make_data_key.js

const provider = "aws";
const kmsProviders = {
  aws: {
    accessKeyId: "<Your AWS Access Key ID>",
    secretAccessKey: "<Your AWS Secret Access Key>",
  },
};

MakeDataKey.cs

var kmsProviders = new Dictionary<string, IReadOnlyDictionary<string, object>>();
const string provider = "aws";
var awsKmsOptions = new Dictionary<string, object>
{
   { "accessKeyId", "<Your AWS Access Key ID>" },
   { "secretAccessKey", "<Your AWS Secret Access Key>" }
};
kmsProviders.Add(provider, awsKmsOptions);

make-data-key.go

provider := "aws"
kmsProviders := map[string]map[string]interface{}{
	provider: {
		"accessKeyId":     "<Your AWS Access Key ID>",
		"secretAccessKey": "<Your AWS Secret Access Key>",
	},
}

MakeDataKey.java

Map<String, Map<String, Object>> kmsProviders = new HashMap<String, Map<String, Object>>();
String kmsProvider = "aws";
Map<String, Object> providerDetails = new HashMap<>();
providerDetails.put("accessKeyId", new BsonString("<IAM User Access Key ID>"));
providerDetails.put("secretAccessKey", new BsonString("<IAM User Secret Access Key>"));
kmsProviders.put(kmsProvider, providerDetails);

make_data_key.js

const provider = "aws";
const kmsProviders = {
  aws: {
    accessKeyId: "<Your AWS Access Key ID>",
    secretAccessKey: "<Your AWS Secret Access Key>",
  },

添加您的密钥信息

更新以下代码以指定客户主密钥：

提示

您在本指南的创建客户主密钥步骤中记录了客户主密钥的 ARN 和地区。

make_data_key.js

const masterKey = {
  key: "<Your AWS Key ARN>",
  region: "<Your AWS Key Region>",
};

MakeDataKey.cs

DataKeyOptions GetDataKeyOptions(List<string> altNames)
{
    var dataKeyOptions = new DataKeyOptions(
       alternateKeyNames: altNames,
       masterKey: new BsonDocument
       {
           { "region", "<Your AWS Key Region>" },
           { "key", "<Your AWS Key ARN>" },
       });
    return dataKeyOptions;
}

make-data-key.go

masterKey := map[string]interface{}{
	"key":    "<Your AWS Key ARN>",

const masterKey = {
  key: "<Your AWS Key ARN>",
  region: "<Your AWS Key Region>",
};

make_data_key.py

master_key = {"region": "<Master Key AWS Region>", "key": "<Master Key ARN>"}

创建数据加密密钥

使用 MongoDB 连接字符串和密钥保管库集合命名空间构建客户端，并创建数据加密密钥：

注意

密钥保管库集合命名空间权限

本指南中的“密钥保管库集合”是encryption数据库中的__keyVault集合。确保应用程序用于连接到 MongoDB 的数据库用户对encryption.__keyVault命名空间具有ReadWrite权限。

make_data_key.js

const autoEncryptionOpts = {
  keyVaultNamespace: keyVaultNamespace,
  kmsProviders: kmsProviders,
};
const encClient = Mongo(uri, autoEncryptionOpts);
const keyVault = encClient.getKeyVault();
const dek1 = keyVault.createKey(provider, {
  masterKey: masterKey,
  keyAltNames: ["dataKey1"],
});
const dek2 = keyVault.createKey(provider, {
  masterKey: masterKey,
  keyAltNames: ["dataKey2"],
});
const dek3 = keyVault.createKey(provider, {
  masterKey: masterKey,
  keyAltNames: ["dataKey3"],
});
const dek4 = keyVault.createKey(provider, {
  masterKey: masterKey,
  keyAltNames: ["dataKey4"],
});

make_data_key.js

const encryptedFieldsMap = {
  [`${secretDB}.${secretCollection}`]: {
    fields: [
      {
        keyId: dek1,
        path: "patientId",
        bsonType: "int",
        queries: { queryType: "equality" },
      },
      {
        keyId: dek2,
        path: "medications",
        bsonType: "array",
      },
      {
        keyId: dek3,
        path: "patientRecord.ssn",
        bsonType: "string",
        queries: { queryType: "equality" },
      },
      {
        keyId: dek4,
        path: "patientRecord.billing",
        bsonType: "object",
      },
    ],
  },
};
try {
  const autoEncryptionOptions = {
    keyVaultNamespace: keyVaultNamespace,
    kmsProviders: kmsProviders,
    encryptedFieldsMap: encryptedFieldsMap,
  };
  const encClient = Mongo(uri, autoEncryptionOptions);
  const newEncDB = encClient.getDB(secretDB);
  // Drop the encrypted collection in case you created this collection
  // in a previous run of this application.
  newEncDB.dropDatabase();
  newEncDB.createCollection(secretCollection);
  console.log("Created encrypted collection!");

指定自动加密共享库位置

// mongosh does not require you to specify the
// location of the Automatic Encryption Shared Library

InsertEncryptedDocument.cs

var extraOptions = new Dictionary<string, object>()
{
   { "cryptSharedLibPath", "<path to crypt_shared library>" },
};

insert-encrypted-document.go

extraOptions := map[string]interface{}{
	"cryptSharedLibPath": "<Your Crypt Shared lib Path>",
}

InsertEncryptedDocument.java

Map<String, Object> extraOptions = new HashMap<String, Object>();
extraOptions.put("cryptSharedLibPath", "<path to crypt_shared>");

insert_encrypted_document.js

const extraOptions = {
  cryptSharedLibPath: "<path to FLE Shared Library>",
};

insert_encrypted_document.py

auto_encryption = AutoEncryptionOpts(
    kms_providers,
    key_vault_namespace,
    encrypted_fields_map=encrypted_fields_map,
    schema_map=None,
    crypt_shared_lib_path="<path to FLE Shared Library>",
)

注意

自动加密选项

自动加密选项向自动加密共享库提供配置信息，这将修改应用程序在访问加密字段时的行为。

要了解有关自动加密共享库的更多信息，请参阅 Queryable Encryption 的自动加密共享库页面。

创建 MongoClient

使用以下自动加密设置实例化 MongoDB 客户端对象：

insert_encrypted_document.js

const autoEncryptionOptions = {
  keyVaultNamespace: keyVaultNamespace,
  kmsProviders: kmsProviders,
  bypassQueryAnalysis: false,
  encryptedFieldsMap: encryptedFieldsMap,
};
const encryptedClient = Mongo(uri, autoEncryptionOptions);
const encryptedColl = encryptedClient
  .getDB(secretDB)
  .getCollection(secretColl);
const unencryptedColl = unencryptedClient
  .getDB(secretDB)
  .getCollection(secretColl);

InsertEncryptedDocument.cs

var clientSettings = MongoClientSettings.FromConnectionString(connectionString);
var autoEncryptionOptions = new AutoEncryptionOptions(
    keyVaultNamespace,
    kmsProviders,
    encryptedFieldsMap: encryptedFieldsMap,
    extraOptions: extraOptions
    );
clientSettings.AutoEncryptionOptions = autoEncryptionOptions;
var secureClient = new MongoClient(clientSettings);

insert-encrypted-document.go

autoEncryptionOpts := options.AutoEncryption().
	SetKmsProviders(kmsProviders).
	SetKeyVaultNamespace(keyVaultNamespace).
	SetEncryptedFieldsMap(encryptedFieldsMap).
	SetExtraOptions(extraOptions)
secureClient, err := mongo.Connect(context.TODO(), options.Client().ApplyURI(uri).SetAutoEncryptionOptions(autoEncryptionOpts))
if err != nil {
	return fmt.Errorf("Connect error for encrypted client: %v", err)
}
defer func() {
	_ = secureClient.Disconnect(context.TODO())
}()

InsertEncryptedDocument.java

MongoClientSettings clientSettings = MongoClientSettings.builder()
        .applyConnectionString(new ConnectionString(connectionString))
        .autoEncryptionSettings(AutoEncryptionSettings.builder()
                .keyVaultNamespace(keyVaultNamespace)
                .kmsProviders(kmsProviders)
                .encryptedFieldsMap(encryptedFieldsMap)
                .extraOptions(extraOptions)
                .build())
        .build();
MongoClient mongoClientSecure = MongoClients.create(clientSettings);

insert_encrypted_document.js

const encryptedClient = new MongoClient(uri, {
  autoEncryption: {
    keyVaultNamespace: keyVaultNamespace,
    kmsProviders: kmsProviders,
    extraOptions: extraOptions,
    encryptedFieldsMap: encryptedFieldsMap,
  },
});
await encryptedClient.connect();

insert_encrypted_document.py

secure_client = MongoClient(connection_string, auto_encryption_opts=auto_encryption)

插入具有加密字段的文档

使用已启用 Queryable Encryption 的实例MongoClient，通过以下代码段将加密文档插入到命名空间medicalRecords.patients中：

insert_encrypted_document.js

encryptedColl.insertOne({
  firstName: "Jon",
  lastName: "Doe",
  patientId: 12345678,
  address: "157 Electric Ave.",

  },
  medications: ["Atorvastatin", "Levothyroxine"],
});

InsertEncryptedDocument.cs

var sampleDocument = new BsonDocument
{
    {"firstName", "Jon"},
    {"lastName", "Doe"},
    {"patientId", 12345678},
    {"address", "157 Electric Ave."},
    {
        "medications", new BsonArray
        {
            new BsonString("Atorvastatin"),
            new BsonString("Levothyroxine")

                }
            }
        }
    }
};
var secureCollection = secureClient.GetDatabase(encryptedCollectionNamespace.DatabaseNamespace.DatabaseName)
    .GetCollection<BsonDocument>(encryptedCollectionNamespace.CollectionName);
secureCollection.InsertOne(sampleDocument);

insert-encrypted-document.go

test_patient := map[string]interface{}{
	"firstName":   "Jon",
	"lastName":    "Doe",
	"patientId":   12345678,

	},
}
if _, err := secureClient.Database(dbName).Collection(collName).InsertOne(context.TODO(), test_patient); err != nil {
	return fmt.Errorf("InsertOne error: %v", err)
}

InsertEncryptedDocument.java

ArrayList<String> medications = new ArrayList<>();
medications.add("Atorvastatin");
medications.add("Levothyroxine");
Document patientRecord = new Document()
        .append("ssn", "987-65-4320")
        .append("billing", new Document().append("type", "Visa").append("number", "4111111111111111"));
Document patient = new Document()
        .append("firstName", "Jon")
        .append("lastName", "Doe")
        .append("patientId", 12345678)
        .append("address", "AB+")
        .append("medications", medications)
        .append("patientRecord", patientRecord);
mongoClientSecure.getDatabase(encryptedDbName).getCollection(encryptedCollName).insertOne(patient);

insert_encrypted_document.js

const encryptedColl = encryptedClient
  .db(secretDB)
  .collection(secretCollection);
await encryptedColl.insertOne({
  firstName: "Jon",
  lastName: "Doe",
  patientId: 12345678,
  address: "157 Electric Ave.",
  patientRecord: {
    ssn: "987-65-4320",
    billing: {
      type: "Visa",
      number: "4111111111111111",
    },
  },
  medications: ["Atorvastatin", "Levothyroxine"],
});

insert_encrypted_document.py

encrypted_coll = secure_client[encrypted_db_name][encrypted_coll_name]
encrypted_coll.insert_one(
    {
        "firstName": "Jon",
        "lastName": "Doe",
        "patientId": 12345678,
        "address": "157 Electric Ave.",
        "patientRecord": {
            "ssn": "987-65-4320",
            "billing": {
                "type": "Visa",
                "number": "4111111111111111",
            },
        },
        "medications": ["Atorvastatin", "Levothyroxine"],
    }
)

插入文档时，启用了 Queryable Encryption 的客户端会对文档的字段进行加密，如下所示：

{
  "_id": { "$oid": "<_id value>" },
  "firstName": "Jon",
  "lastName": "Doe",
  "patientId": {
    "$binary": {
      "base64": "<ciphertext>",
      "subType": "06"
    }
  },
  "address": "157 Electric Ave.",
  "patientRecord": {
    "ssn": {
      "$binary": {
        "base64": "<ciphertext>",
        "subType": "06"
      }
    },
    "billing": {
      "$binary": {
        "base64": "<ciphertext>",
        "subType": "06"
      }
    }
  },
  "medications": {
    "$binary": {
      "base64": "<ciphertext>",
      "subType": "06"
    }
  },
  "__safeContent__": [
    {
      "$binary": {
        "base64": "<ciphertext>",
        "subType": "00"
      }
    },
    {
      "$binary": {
        "base64": "<ciphertext>",
        "subType": "00"
      }
    }
  ]
}

警告

不要修改 safeContent 字段

__safeContent__ 字段对于 Queryable Encryption 至关重要。请勿修改此字段的内容。
