Abstract

The explosive growth in computer systems and their interconnections via networks has increased the dependence of both organizations and individuals on the information stored and communicated using these systems. This, in turn, has led to an awareness of the need to protect data and resources from disclosure by using different cryptographic techniques. This paper provides a modified polyalphabetic symmetrical auto-key encryption technique for Arabic letters using a modified polyalphabetic cipher block chaining
