Hi Sir,
My customer has been complaining of slow performance of remote-access VPN over wireless broadband network. They should be using Cisco VPN clients and PIX/VPN Concentrator, though I'm not very certain.
When they change the encryption from 3DES to AES, performance seems to improve.
Can you show me any whitepaper that discusses 3DES vs. AES? I'm interested to understand the comparison between the two algorithms in terms of performance and security.
Thank you.
B.Rgds,
Lim TS
