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 five of the most common encryption algorithms namely: AES (Rijndael), DES, 3DES, RC2 and RC6. A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as different sizes of data blocks, battery power consumption, different key size and finally encryption/decryption speed.

This paper presents a performance evaluation of selected symmetric encryption algorithms. The selected algorithms are AES, DES, 3DES, RC6 and RC2. Several points can be concluded from the simulation results. First; there is no significant difference when the results are displayed for encryption or decryption. Secondly; in the case of changing packet size, it was concluded that RC6 has better performance than other common encryption algorithms used. Third; in the case of changing key size – it can be seen that higher key size leads to clear change in the battery and time consumption. Also, we find that 3DES still has low performance compared to algorithm DES.
