Computer Security Resource Center
The Computer Security Resource Center is one of eight divisions within the Information Technology Laboratory of the National Institute of Standards and Technology (NIST), a US federal technology agency that develops and promotes measurement, standards, and technology. The Computer Security Division is involved with many different projects and CSRC provides Webpages based on these projects.
The site provides access to documents concerned with the development of the US government's computer security policy, including definitions of encryption, cryptography and authorisation procedures. There is an up-to-date news section as well as publications available in HTML and PDF format, and links to other computer security pages.
