1) Add/revise the following definitions:
Issuance Time: The time at which a Certificate’s digital signature is calculated.
Short-Lived Certificate: A Certificate with a Validity Period less than 96 hours and a notBefore time no earlier than 24 hours before the Issuance Time and a notAfter time no later than 72 hours after the Issuance Time.
Validity Period: The period of time measured from notBefore through notAfter, inclusive. the date when the Certificate is issued until the Expiry Date.
2) Modify Section 4.9.10 as follows:
4.9.10. On‐line Revocation Checking Requirements
Effective 1 January 2013, the CA SHALL support an OCSP capability using the GET method for Certificates issued in accordance with these Requirements.
For the status of Subscriber Certificates other than a Short-Lived Certificate containing a cRLDistributionPoints extension: The CA SHALL update information provided via an Online Certificate Status Protocol at least every four days. OCSP responses from this service MUST have a maximum expiration time of ten days.
3) Modify Section 126.96.36.199 as follows:
188.8.131.52. Subscriber Certificate …
b. cRLDistributionPoints This extension MUST be present for Short-Lived Certificates that lack an authorityInformationAccess extension and MAY be present for all other certificates. If present, it MUST NOT be marked critical, and it MUST contain the HTTP URL of the CA’s CRL service. See Section 13.2.1 for details.
c. authorityInformationAccess With the exception of stapling and Short-Lived Certificates, which is noted below, this extension MUST be present. It MUST NOT be marked critical, and it MUST contain the HTTP URL of the Issuing CA’s OCSP responder (accessMethod = 184.108.40.206.220.127.116.11.1). It SHOULD also contain the HTTP URL of the Issuing CA’s certificate (accessMethod = 18.104.22.168.22.214.171.124.2).
The HTTP URL of the Issuing CA’s OCSP responder MAY be omitted for Short-Lived Certificates containing a cRLDistributionPoints extension or if Subscriber “staples” OCSP responses for the Certificate in its TLS handshakes [RFC4366].
