[Based on NIST SP 800-63-2]\\r\\n\\n                        Basic authentication process level of assurance indicates that long-term shared authentication secrets are never revealed to any other party except Credential Service Provider (CSP).  Sessions (temporary) shared secrets may be provided to independent verifiers by CSP. Long-term shared authentication secrets, if used, are never revealed to any other party except Verifiers operated by the Credential Service Provider (CSP); however, session (temporary) shared secrets may be provided to independent Verifiers by the CSP. In addition to Level 1 requirements, assertions are resistant to disclosure, redirection, capture and substitution attacks. Approved cryptographic techniques are required.  [Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.]",
