4.2.3 Credential Technology | These InCommon IAPs are based on use of “shared Authentication Secret” forms of identity Credentials. If other Credentials are used to authenticate the Subject to the IdP, they must meet or exceed the effect of these requirements. | ||
Criteria | Management Assertion | ||
.1 Credential unique identifier | 1. The institution's personal digital certificate (PDC) is issued with a Subject Distinguished Name (DN) and a serial number.The serial number is a unique number in the serial number field. The DN of the PDC contains a UID. The UID is a uniquely assigned attribute of a person in the institution's Enterprise Directory. See the {link to cetificate profile} for a complete description of the certificate DN. The serial number and the UID distinguish the PDC from all other Credentials issued by the IdPO. | ||
.2 Resistance to guessing Authentication Secret | See 4.2.3.3, Strong Resistance | ||
.3 Strong resistance to guessing Authentication | 1. The institution's PDC on the MF device provides cryptographic strength mechanisms described in NIST [SP 800-63] for Level 3 and 4 assurance, protecting the private key against compromise by on-line guessing. The device is a multi-factor "hard" cryptographic token, requiring the user to unlock the device with a password in order to access the private key. | ]]></ac:plain-text-body></ac:structured-macro> | |

The private key cannot be exported off the device; thus it is not escrowed. The MF hardware cryptographic module for the token used by the institution is certified at FIPS 140-2 Level 2, with physical security at FIPS 140-2 level 32. {insert link to FIPS 140 Certificate here}. This credential protects stored secrets at NIST [SP 800-6] assurance Level 43, thus meeting the criteria for method 3 in section 4.2.3.4 of the IAP. | ]]></ac:plain-text-body></ac:structured-macro> |
.5 Protected Authentication Secrets | 1. When issuing personal digital certificate credentials, the MF cryptogrpahic device generates and stores the user’s RSA key pair inside the protected environment of the smart chip in the device. The user’s private key component is never transmitted to another Credential Store and is permanently kept on the device. Access to the private key component on the device is password protected and implements a lockout threshold of 10 consecutive invalid password attempts. |
