الملخص EN

The use of Cryptography of text Authentication has become a standard approach in many applications, particularly in Internet Security Protocols.

This research describes a new approach of authentication text and can be applied to text chatting system.

This work presents simple and practical constructions Message Authentication Code (MAC) based on a cryptographic hash function.

The proposed MAC Code provides security and authenticity for any length of messages, furthermore it is fast and easy to implement.
