Method and corresponding apparatus for processing a data stream received by a wireless communication device and at least partially requiring cryptographic processing operations

摘要

Wireless communication apparatus (WAP) which comprises means of receiving data streams such as Access Stratum User Plane (AS UP), Access Stratum Control Plane (AS CP), and Non-Access Stratum Control Plane (NAS CP), each at least partly requiring a cryptographic processing operation, a cryptographic module comprising a cryptoprocessor, and management means configured to deliver at least some of the data streams to the crypto-processor according to an order of priority defined from the data types and cryptographic processing types assigned to each data stream.
