[VPN] AES and 3DES performance on Cisco routers

[Brian V. Minier]

Well, from the Cisco website on a PIX firewall

 

The compact desktop chassis of the Cisco PIX 506E provides two autosensing
Fast Ethernet (10/100) interfaces. Ideal for securing high-speed Internet
connections, the Cisco PIX 506E delivers up to 100 Mbps of firewall
throughput, 16 Mbps of Triple Data Encryption Standard VPN throughput, and
30 Mbps of Advanced Encryption Standard-128 VPN throughput in a
cost-effective, high-performance solution.

 

So, it looks like AES 128 is roughly 2x as fast as 3DES.  I would hazard a
guess and say AES256 would than be about as fast as 3DES.

Can someone on the group comment on the speeds that a Cisco router with HW
acceleration used for a VPN end point can reach using AES128, AES256 and
3DES?

 

TIA,
