IKE algorithms are computationally expensive, particularly in the Phase 1 exchange. Systems that handle a large number of exchanges can use a Sun Crypto Accelerator 1000 board to handle the public key operations. The Sun Crypto Accelerator 6000 and Sun Crypto Accelerator 4000 boards can also be used to handle expensive Phase 1 computations.
For information on how to configure IKE to offload its computations to the accelerator board, see How to Configure IKE to Find the Sun Crypto Accelerator 1000 Board. For information on how to store keys, see How to Configure IKE to Find the Sun Crypto Accelerator 4000 Board, and the cryptoadm(1M) man page.
