  "definition" : "Indicator of the medium digital quality or reliability of a defined sequence of messages between a Claimant and a Verifier that demonstrates that the Claimant has possession and control of a valid token to establish his/her identity, and optionally, demonstrates to the Claimant that he or she is communicating with the intended Verifier. [Based on NIST SP 800-63-2]\\r\\n\\n                        Medium authentication process level of assurance indicates that the token can be unlocked with password, biometric, or uses a secure multi-token authentication protocol to establish two-factor authentication.  Long-term shared authentication secrets are never revealed to any party except the Claimant and Credential Service Provider (CSP).\\r\\n\\n                        Authentication requires that the Claimant prove, through a secure authentication protocol, that he or she controls the token. The Claimant unlocks the token with a password or biometric, or uses a secure multi-token authentication protocol to establish two-factor authentication (through proof of possession of a physical or software token in combination with some memorized secret knowledge). Long-term shared authentication secrets, if used, are never revealed to any party except the Claimant and Verifiers operated directly by the CSP; however, session (temporary) shared secrets may be provided to independent Verifiers by the CSP. In addition to Level 2 requirements, assertions are protected against repudiation by the Verifier.",
