Editing Secure cryptoprocessor (section)

==Features==
Security measures used in secure cryptoprocessors:
* Tamper-detecting and [[tamper-evident]] containment.
* Conductive shield layers in the chip that prevent reading of internal signals.
* Controlled execution to prevent timing delays from revealing any secret information.
* Automatic [[zeroisation|zeroization]] of secrets in the event of tampering.
* [[Chain of trust]] boot-loader which authenticates the operating system before loading it.
* Chain of trust operating system which authenticates application software before loading it.
* Hardware-based [[Capability-based security|capability]] registers, implementing a one-way [[privilege separation]] model.
