| (I) A Internet protocol for providing client-server security
services for HTTP communications. (See: https.)
(C) S-HTTP was originally specified by CommerceNet, a coalition of
businesses interested in developing the Internet for commercial
uses. Several message formats may be incorporated into S-HTTP
clients and servers, particularly CMS and MOSS. S-HTTP supports
choice of security policies, key management mechanisms, and
cryptographic algorithms through option negotiation between
parties for each transaction. S-HTTP supports both asymmetric and
symmetric key operation modes. S-HTTP attempts to avoid presuming
a particular trust model, but it attempts to facilitate multiply-
rooted hierarchical trust and anticipates that principals may have
many public key certificates.
