Abstract
An application server has a custodian application running thereon. The server receives a command to instantiate a cryptographic microservice application on the application server. In response, the server instantiates the cryptographic microservice application. The cryptographic microservice application builds a secure enclave on the application server and, within the secure enclave, a cryptogram that represents a virtual fingerprint of the cryptographic microservice application. The server transmits the cryptogram to an authentication computing system. The server receives a digitally signed certificate from the authentication computing system and a data encryption key encrypted with a master tenant key from the custodian application. The server transmits a request to the authentication computing system. The request includes the digitally signed certificate, the data encryption key, and a request to decrypt the data encryption key. The server then receives the decrypted data encryption key from the authentication computing system.
