A security circuit using at least two finite state machine units for storing data to and reading data from a multiport memory in a pipelined manner and an intermediate memory, for facilitating transfer of data between the at least two finite state machines. The security circuit may be used to perform key setup and/or data ciphering faster. The security circuit may operate in any environment where the key is changed every frame, for example, a wireless LAN application and the security circuit may operate in conjunction with, or as part of, a MAC controller. |
