                        Basic 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.

                        Medium authentication level of assurance indicates that the relying party may have high confidence in the asserted identity's validity.  Level 3 is appropriate for transactions that need high confidence in the accuracy of the asserted identity. Level 3 provides multifactor remote network authentication. At this level, identity-proofing procedures require verification of identifying materials and information. Authentication is based on proof of possession of a key or password through a cryptographic protocol. Cryptographic strength mechanisms should protect the primary authentication token (a cryptographic key) against compromise by the protocol threats, including eavesdropper, replay, online guessing, verifier impersonation, and man-in-the-middle attacks. A minimum of two authentication factors is required. Three kinds of tokens may be used:

                        
                           "soft" cryptographic token, which has the key stored on a general-purpose computer, 
                           "hard" cryptographic token, which has the key stored on a special hardware device, and 
                           "one-time password" device token, which has symmetric key stored on a personal hardware device that is a cryptographic module validated at FIPS 140-2 Level 1 or higher. Validation testing of cryptographic modules and algorithms for conformance to Federal Information Processing Standard (FIPS) 140-2, Security Requirements for Cryptographic Modules, is managed by NIST.
                        
                        Authentication requires that the claimant prove control of the token through a secure authentication protocol. The token must be unlocked with a password or biometric representation, or a password must be used in a secure authentication protocol, to establish two-factor authentication. 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.

                        High authentication level of assurance indicates that the relying party may have very high confidence in the asserted identity's validity. Level 4 is for transactions that need very high confidence in the accuracy of the asserted identity. Level 4 provides the highest practical assurance of remote network authentication. Authentication is based on proof of possession of a key through a cryptographic protocol. This level is similar to Level 3 except that only “hard� cryptographic tokens are allowed, cryptographic module validation requirements are strengthened, and subsequent critical data transfers must be authenticated via a key that is bound to the authentication process. The token should be a hardware cryptographic module validated at FIPS 140-2 Level 2 or higher overall with at least FIPS 140-2 Level 3 physical security. This level requires a physical token, which cannot readily be copied, and operator authentication at Level 2 and higher, and ensures good, two-factor remote authentication.

                        Level 4 requires strong cryptographic authentication of all parties and all sensitive data transfers between the parties. Either public key or symmetric key technology may be used. Authentication requires that the claimant prove through a secure authentication protocol that the claimant controls the token. Eavesdropper, replay, online guessing, verifier impersonation, and man-in-the-middle attacks are prevented. 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. Strong approved cryptographic techniques are used for all operations. All sensitive data transfers are cryptographically authenticated using keys bound to the authentication process.

A minimum of two authentication factors is required. Three kinds of tokens may be used:\r\n\n                        \n                           \"soft\" cryptographic token, which has the key stored on a general-purpose computer, \n                           \"hard\" cryptographic token, which has the key stored on a special hardware device, and \n                           \"one-time password\" device token, which has symmetric key stored on a personal hardware device that is a cryptographic module validated at FIPS 140-2 Level 1 or higher. Validation testing of cryptographic modules and algorithms for conformance to Federal Information Processing Standard (FIPS) 140-2, Security Requirements for Cryptographic Modules, is managed by NIST.\n                        \n                        Authentication requires that the claimant prove control of the token through a secure authentication protocol. The token must be unlocked with a password or biometric representation, or a password must be used in a secure authentication protocol, to establish two-factor authentication. 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. Approved cryptographic techniques are used for all operations.  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.

Level 4 is for transactions that need very high confidence in the accuracy of the asserted identity. Level 4 provides the highest practical assurance of remote network authentication. Authentication is based on proof of possession of a key through a cryptographic protocol. This level is similar to Level 3 except that only “hard� cryptographic tokens are allowed, cryptographic module validation requirements are strengthened, and subsequent critical data transfers must be authenticated via a key that is bound to the authentication process. The token should be a hardware cryptographic module validated at FIPS 140-2 Level 2 or higher overall with at least FIPS 140-2 Level 3 physical security. This level requires a physical token, which cannot readily be copied, and operator authentication at Level 2 and higher, and ensures good, two-factor remote authentication.\r\n\n                        Level 4 requires strong cryptographic authentication of all parties and all sensitive data transfers between the parties. Either public key or symmetric key technology may be used. Authentication requires that the claimant prove through a secure authentication protocol that the claimant controls the token. Eavesdropper, replay, online guessing, verifier impersonation, and man-in-the-middle attacks are prevented. 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.
