Abstract: Cryptography is used in almost in every application to provide strong security to sensitive data during the communication across the public network. In this study, a performance analysis is conducted to find the optimal encryption cipher to provide a better performance during encryption process in the IPSec tunnel mode. The analysis is based on the comparison of number of delay and jitter between block cipher (DES-56 bits, 3DES-168 bits and AES-256 bits) and stream cipher (SEAL) used in IPSec encryption security payload. The result shows that 160 bits SEAL cipher has the least latency in encrypting the TCP and UDP traffic in both single and multi uses compared to other ciphers.
