This page should be merged with Hardware Security Modules, as this is just an example of embedded HSM application, rather than different technology. References should be cleaned up, most of them are just direct links to commercial websites. 12.43.237.215 ( talk) 21:39, 22 September 2008 (UTC)
Don't merge - Secure cryptoprocessor is a distinct subcategory of HSM, just as automobile is a distinct subcategory of vehicle, and horse is a distinct subcategory of mammal, and Hardware Security Module is a distinct subcategory of computer. You wouldn't think of merging those would you? Just because a processor does crypto in a locked box does not make it a secure cryptoprocessor. "Secure" is in the narrow sense that it cannot reveal its secrets to anybody, not even to its owner, which implies a single chip. The owner of a computer module in a locked box such as an ATM, who has the combination to the ATM, can access the keys and plaintext on the bus, unless the ATM module or motherboard has a secure cryptoprocessor in it. The secure cryptoprocessor is then a component in the HSM along with other components such as a graphics chip and ROM. Components such as graphics chips and ROMs are distinct from computers and Hardware Security Modules and therefore have separate Wiki articles. 4.235.81.173 ( talk) 01:14, 23 September 2008 (UTC)
References need to be cleaned up. Following:
* IBMs homepage for its cryptoprocessors * Extracting a 3DES key from an IBM 4758 * SafeNet security processors

The article attempts to distinguish between secure cryptoprocessors and cryptoprocessors (albeit cryptoprocessors redirects to secure cryptoprocessors). In particular, it is claimed that "cryptographic processors [may] output decrypted data onto a bus in a secure environment, [whereas] a secure cryptoprocessor [may never] output decrypted data [...] in an [insecure] environment." This is clearly not a distinction, since secure cryptoprocessors may output decrypted data onto a bus in a secure environment, just like a cryptoprocessor.
A number of companies make actual cryptoprocessor chips for their various use cases. For example, NXP (Formerly Phillips) makes some CryptoProcessors that they sell to companies making SmartCards, car keys etc. Gemalto/Thales may or may not be making their own Cryptoprocessor chips used in their smartcards and HSM products. Generic CPUs with cryptographic abilities typically are not cryptoprocessors, although some modern CPU chips include embedded CryptoProcessors as supporting hardware (such as the separate core running the trusted chip management code in Intel and AMD CPUs or the separate core acting as an Embedded eSim smartcard in some modern Smartphone CPU chips).
