Method and system for allowing for the secure transmission and reception of data in a processing system

摘要

A method and system for allowing for the secure transmission and reception of data in a processing system is disclosed. The method and system includes providing at least one crypto algorithm in a region of a system memory in the processing system; and assigning a cryptographic function of the at least one crypto algorithm to the region. A system and method in accordance with the present invention ties the encryption/decryption algorithm to specific DMA regions and the encryption key to the particular DMA transfer. This allows the system processors to offload the encryption and enable all network (and non-network) adapters to take advantage of this offload without hardware changes to the adapters.
