Client microservice for secure and efficient searchable encryption

Abstract:

Disclosed embodiments relate to implementing, as a microservice at a client, a searchable-encryption service. Operations may include executing the microservice at the client to perform operations including: encrypting data based on a cryptographic key accessible to the client; sending the encrypted data to a network storage resource; identifying, at the microservice, a search query in plaintext; encrypting the search query according to the cryptographic key; sending the encrypted search query to the network storage resource; and receiving a response to the encrypted search query from the network storage resource.
