Abstract
In this article, we propose a two-phase encryption algorithm for data base systems. The system, a record-oriented cryptosystem, allows the e ncryption and decryption of fields within a record by means of writing and reading subkeys of fields. In addition, we develop two algorithms for cryptographic relational algebra in data base systems. Two simple methods of solving the key management problem in the subkey scheme ar e presented.
