Sun Plans Security Coprocessor For New Ultrasparc 59
angry tapir writes "At the Hot Chips conference at Stanford University, Sun presented plans for a security accelerator chip that it said would reduce encryption costs for applications such as VoIP calls and online banking Web sites. The coprocessor will be included on the same silicon as Rainbow Falls, the code name for the follow-on to Sun's multi-threaded Ultrasparc T2 processor."

Again, the people that understand the difference don't need it explained to them. Those that don't -- the ones that sign the checks -- will just be confused. Now, even more so if you bring up trusted execution.
Sun's been doing encryption offload since well before Via added it on their chips. This is just a new revision of their crypto accelerator board. Personally, I've been using these [soekris.com] for years. Cheap and effective.

The T1 and T2 have different cryptographic capabilities. See page 5 of "Using the Cryptographic Accelerators" [sun.com] a description. I would imagine that they are including even more support.

Not much difference, it's just third iteration of in-CPU crypto accells. See details in presentation [sun.com].

The T1 only has hardware to help with the initial key exchange. SSL traffic starts with an RSA key exchange using a a huge public/private key and then uses a block cypher like DES or SHA or RC4 to encrypt the data using the key that was exchanged via the RSA encryption. The T1 can't do block cyphers quickly and only has the first part speeded up. I found that my amd based X2100 would catch up to the T1 based T1000 after about 3000 bytes of an SSL stream and then quickly pass it. I've been told that the T1 was supposed to have block cypher hardware but maybe it was buggy and was disabled. Anyway sun should kill the T1 since its slow and expensive. Maybe thats their intent with their new T3120 but few details have been released.
