Cloud based key management

Abstract:

Embodiments are directed to managing cryptographic keys in a multi-tenant cloud based system. Embodiments receive from a client a request for a wrapped data encryption key ("DEK"). Embodiments generate a random key and fetch encryption context that corresponds to the client. Embodiments generate the wrapped DEK including the random key and the encryption context encoded in the wrapped DEK. Embodiments then return the wrapped DEK to the client.
