Secure/Multipurpose Internet Mail Extensions

S/MIME uses Cryptographic Message Syntax (CMS) to secure and authenticate each individual message. Since each message is secured seperately each message can have different level or type of security depending on the need. CMS also accommodates multiple layers of security being applied on top of each other.
