Secure and Fast Encryption Routine+: Evaluation by Software Application

Abstract

Nowadays, the Internet era and its components are based on the collection, exchange, and storage of information which represent a sever security concern. Many cipher algorithms have been developed, evaluated, and implemented to increase the protection of data for various applications. The most known strategy of data securing has been the implementation of symmetrical key encryption standards. Secrecy, robustness, reliability, and software/ hardware implementation, are among the most important properties of good cipher standard. In this work, text, data and image encryption/decryption are performed by a MATLAB software implementation of the symmetric key block standard realized using the Secure and Fast Encryption Routine (SAFER+) algorithm with 128 key length option. The results show good performances in encryption/ decryption speed through a set of original procedures to simplify the achievement of nonlinear functions adopted by SAFER+ structure.
