JIGSAW KEY ENCRYPTION/DECRYPTION

Abstract:

A computer-implemented method for generating a symmetric key for data encryption includes receiving a first request from an entity to generate a first symmetric key for data encryption. The computer-implemented method further includes retrieving a first secret data element and a second secret data element from one or more secret data servers. The computer-implemented method further includes dividing each of the first secret data element and the second secret data element into a number of secret data element byte strings. The computer-implemented method further includes generating the first symmetric key for data encryption based, at least in part, on combining a first secret data element byte string from the first secret data element and a second secret data element byte string from the second secret data element.
