In essence, the recipient signs the entire originaI message plus originaI (sender"s) signature and appends the new signature to form a new S/MIME message.

Security labels: A security Iabel may be included in the authenticated attributes of a SignedData object. A security Iabel is a set of security information regarding the sensitivity of the content that is protected by S/MIME encapsuIation. The Iabeis may be used for access controI, by indicating which users are permitted access to an object.

Other uses include priority (secret, confidentiaI, restricted, and so on) or role based, describing which kind of people can see the information (e.g., patient"s health-care team, medicaI billing agents, etc.

). Secure mailing lists: When a user sends a message to multiple recipients, a certain amount of per-recipient processing is required, including the use of each.
