Testing of the equipment is very essential before being put into service. The testing has to be done by the latest technique. This paper describes a generic built-in self-test strategy for crypto-devices with sub pipelining architecture by implementing symmetric encryption algorithms. Taking advantage of the inner iterative structures of crypto-cores, test facilities are easily set-up for self-test of the crypto-cores, built-in pseudorandom test generation. Main advantages of the proposed test implementation are high throughput and no visible scan chain, this testing provides crypto-cores with 100% fault coverage with a notable speed has been achieved in the range of 3.22Gbps for 128-bit AES algorithm.
