Abstract:
There are many situations where organizations want to protect
information with robust access control, either for implementation of
intellectual property right protections, enforcement of contractual
confidentiality agreements or because of legal regulations. The
Enhanced Security Services (ESS) for S/MIME defines an access control
mechanism for email which is enforced by the recipient's client after
decryption of the message. The ESS mechanism therefore is dependent
on the correct access policy configuration of every recipient's
client. This mechanism also provides full access to the data to all
recipients prior to the access control check, which is considered to
be inadequate for robust access control due to the difficulty in
demonstrating policy compliance.
This document lays out the deficiencies of the current ESS security
label, and presents requirements for a new model for providing access
control to messages where the access check is performed prior to
message content decryption. This new model also does not require
policy configuration on the client thereby simplifying deployment and
compliance verification.
The proposed model additionally provides a method where non-X.509
certificate credentials can be used for encryption/decryption of
S/MIME messages.
The name Plasma was assigned to this effort as part of the IETF
process. It is derived from PoLicy enhAnced Secure eMAil.
