What is the CESG Assisted Products Scheme (CAPS)?
The UK Government’s Communications-Electronic Security Group (CESG) Assisted Products Scheme (CAPS) is an effort to help commercial product vendors produce cryptographic products suitable for use by the British Government for all but the most sensitive applications. CAPS has a similar purpose for the UK Government as FIPS 140 does for the US and Canadian Governments, and as the Cryptographic Advisory Note (CAN) does for the Australian and New Zealand Governments.
