摘要： A dual cryptographic keying system. In particular implementations, a method includes responsive to an initial session key negotiation, storing security association information for a tunnel in a security association memory; responsive to a session key renegotiation, storing security association information for the tunnel in a cache; decrypting received packets associated with the tunnel conditionally using the security association information in the cache or the security association information in the security association memory; and upon an expiration condition, overwriting the security association information, for the tunnel, in the security association memory with the security association information, for the tunnel, copied from the cache.

摘要： A method and apparatus for testing a digital integrated circuit (IC) for faults wherein the IC includes a memory, a microprocessor, an operand register, and a random data generator which is responsive to integrated circuit data indicative of the instantaneous IC state. A short test code including operational code instructions in the memory is performed by the microprocessor which manipulates data in the operand register. Periodically, the random data generator provides seed data to the microprocessor which changes the test code in a random manner and modifies the data stored in the operand register. At the end of a prescribed number of passes through the test code, the data generator produces an IC signature which can be compared to a known correct signature to identify IC faults.
