  "definition" : "Indicator of basic digital quality or reliability of the digital reliability of the verification and validation process used to verify the claimed identity of an entity by securely associating an identifier and its authenticator. \\\\[Based on ISO 7498-2\\\\]\\r\\n\\r\\nThe degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. \\\\[OMB M-04-04 E-Authentication Guidance for Federal Agencies\\\\]\\r\\n\\r\\nBasic authentication level of assurance indicates that the relying party may have some confidence in the asserted identity's validity. Level 2 requires confidence that the asserted identity is accurate. Level 2 provides for single-factor remote network authentication, including identity-proofing requirements for presentation of identifying materials or information. A wide range of available authentication technologies can be employed, including any of the token methods of Levels 3 or 4, as well as passwords. Successful authentication requires that the claimant prove through a secure authentication protocol that the claimant controls the token. Eavesdropper, replay, and online guessing attacks are prevented. Long-term shared authentication secrets, if used, are never revealed to any party except the claimant and verifiers operated by the CSP; however, session (temporary) shared secrets may be provided to independent verifiers by the CSP. Approved cryptographic techniques are required. Assertions issued about claimants as a result of a successful authentication are either cryptographically authenticated by relying parties (using approved methods) or are obtained directly from a trusted party via a secure authentication protocol. \\\\[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.\\\\]",
