RECONFIGURABLE KEY SEARCH ENGINE |
摘要 |
A Reconfigurable Key Search Engine (RKSE) in a mobile communication unit is adapted to efficiently search a memory system storing a plurality of security keys related to multiple networks. One embodiment uses a hierarchical memory system comprising multiple memories each comprising an associative memory storing an index output and a memory storing a security key. The mobile communication unit roaming across a plurality of wireless networks identifies an incoming packet and derives index data to search a content addressable memory for an address. The address is used to obtain a security key from a memory. The key is used to decrypt the packet. The RKSE provides fast retrieval of the correct encryption key to decrypt the received packet. |
