Crypto Co-Processor Board

The unit serves as a crypto co-processor for securing TM/TC links. It provides authentication between Satellite and Ground Station and establishes a highly secured communication channel for key exchange. On the packet level, encryption/decryption of TM/TC packets is performed.
