Abstract : A simple enciphering technique that can be used to encode sensitive data in computer systems is described. This cipher has properties that make it possible to do editing on data within the computer without decoding. Thus, the key need not be available to the computer nor anyone who has access to the computer system since the deciphered at its origin or its destination by use of a very simple ciphering procedure. Requirements for computational cryptography are also discussed along with a short review of cryptographic techniques that have already been used for computer systems. Finally, some problems that still remain unsolved will be illustrated. (Author)
