Abstract Internet and networks applications are growing very fast, so the needs to protect
such applications are increased. Encryption algorithms play a main role in information
security systems. On the other side, those algorithms consume a significant amount of
computing resources such as CPU time, memory, and battery power. This paper provides
evaluation of six of the most common encryption algorithms namely: AES (Rijndael), DES,
3DES, RC2, Blowfish, and RC6. A comparison has been conducted for those encryption ...
