The PKIX and S/MIME Working Groups have been closed for some time. Some updates have been proposed to the X.509 certificate documents produced by the PKIX Working Group and the electronic mail security documents produced by the S/MIME Working Group. The LAMPS (Limited Additional Mechanisms for PKIX and SMIME) Working Group is chartered to make updates where there is a known constituency interested in real deployment and there is at least one sufficiently well specified approach to the update so that the working group can sensibly evaluate whether to adopt a proposal. The LAMPS WG is now tackling these topics: 1. Specify the use of short-lived X.509 certificates for which no revocation information is made available by the Certification Authority. Short-lived certificates have a lifespan that is shorter than the time needed to detect, report, and distribute revocation information. As a result, revoking short-lived certificates is unnecessary and pointless. 2. Update the specification for the cryptographic protection of email headers -- both for signatures and encryption -- to improve the implementation situation with respect to privacy, security, usability and interoperability in cryptographically-protected electronic mail. Most current implementations of cryptographically-protected electronic mail protect only the body of the message, which leaves significant room for attacks against otherwise-protected messages. 3. The Certificate Management Protocol (CMP) is specified in RFC 4210, and it offers a vast range of certificate management options. CMP is currently being used in many different industrial environments, but it needs to be tailored to the specific needs of such machine-to-machine scenarios and communication among PKI management entities. The LAMPS WG will develop a "lightweight" profile of CMP to more efficiently support of these environments and better facilitate interoperable implementation, while preserving cryptographic algorithm agility. In addition, necessary updates and clarifications to CMP will be specified in a separate document. This work will be coordinated with the LWIG WG. In addition, the LAMPS WG may investigate other updates to documents produced by the PKIX and S/MIME WG. The LAMPS WG may produce clarifications where needed, but the LAMPS WG shall not adopt anything beyond clarifications without rechartering.
