摘要
In a wireless communication system, a method and system for hardware accelerator for implementing the f8 confidentiality algorithm in WCDMA compliant handsets are provided. Input variables may be initialized in a keystream generator and an intermediate value may be generated with a confidentiality key parameter and a key modifier. The number of processing blocks of output bits may be based on the length of the input bitstream. The processing blocks of output bits may be generated utilizing a KASUMI operation and may be based on an immediately previous processing block of output bits, the intermediate value, and an indication of the current processing block of output bits. The processing blocks of output bits may be generated after an indication that an immediately previous processing block of output bits is available. The keystream generator may indicate when a first and any additional processing blocks of output bits have been determined.
