A secure cryptoprocessor is a dedicated computer or microprocessor for carrying out cryptograpic operations, embedded in a packaging with multiple physical security measures, which give it a degree of tamper resistance. Cryptoprocessors input program instructions in encrypted form, decrypt the instructions to plain instructions which are then executed within the same cryptoprocessor chip where the decrypted instructions are inaccessibly stored. By never revealing the decrypted program instructions, the cryptoprocessor prevents tampering of programs by technicians who may have legitimate access to the sub-system data bus.

  • 15. A secure cryptoprocessor is a dedicated computer or microprocessor for carrying out cryptograpic operations, embedded in a packaging with multiple physical security measures, which give it a degree of tamper resistance. Cryptoprocessors input program instructions in encrypted form, decrypt the instructions to plain instructions which are then executed within the same cryptoprocessor chip where the decrypted instructions are inaccessibly stored. By never revealing the decrypted program instructions, the cryptoprocessor prevents tampering of programs by technicians who may have legitimate access to the sub-system data bus.
