Merge this article
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)
- I disagree. Name few clear distinctions between HSMs and cryptoprocessors as presented in this article. From HSM "A Hardware Security Module (often abbreviated to HSM) is a physical device in form of a plug-in card or an external security device that can be attached to general purpose computer and servers." Hardware Security Module *is* a cryptoprocessor, they both perform *only* cryptographic calculations, they both have various levels of tamper resistance. You need to ether expand (with references) on these differences or consider merging articles.
