ENCRYPTION PROCESSING APPARATUS FOR HIGH SPEED RADIO NETWORK SWITCH

摘要

PURPOSE: An encryption processing apparatus for a high speed radio network switch is provided to process much data at a time with high throughput and little response time and to process little data rapidly with a little delay time. CONSTITUTION: According to the encryption processing apparatus for a high speed radio network switch performing security processing and integrity verification encryption algorithm processing in the high speed radio network switch, a memory memorizing device part(101) stores input/output protocol packet or data and command and control signals extracted from the packet. A shared memory memorizing device part(102) stores a packet and a control signal and command and data extracted from the packet. A memory control part(105) performs input/output control and synchronization of the memory memorizing device part and the shared memory memorizing device part. An encryption processing device part(107) processes security and integrity verification encryption algorithm. An external input/output control part(108) controls external input/output. An external network interface block(109) performs packet analysis operation as to a packet received from an external network connection network, and transmits the analyzed packet to the encryption processing device part or the memory memorizing device part or the shared memory memorizing device part. And a central processing part(100) performs basic protocol analysis and packet processing, memory management, shared memory management and encryption processor control.
