Issue Description
In MDM v3.0, FIA_X509_EXT.1.1 requires that any PP compliance using CRLs requires compliance to RFC 5759 (bullet #4) which is specifically written around Suite B cryptography and requires the use of ECDSA. RFC 5280 defines the use of CRLs, their signatures, etc. without mandating ECDSA. Resolution
FIA_X509_EXT.1.1, Bullet #4 is replaced as follows to allow compliance to RFC 5280 for CRLs: · The TSF shall validate the revocation status of the certificate using [selection: the Online Certificate Status Protocol (OCSP) as specified in RFC 2560, a Certificate Revocation List (CRL) as specified in RFC 5280 Section 6.3, a Certificate Revocation List (CRL) as specified in RFC 5759 Section 5]. Justification
The MDM PP does not require elliptic curve; it is optional. Therefore, mandating EC for CRL signing is inconsistent. This aligns with TD0217 & TD0169. |
