Security Mechanisms

May be incorporated into the appropriate protocol layer in order to provide some of the OSI security services.

Encipherment The use of mathematical algorithms to transform data into a form that is not readily intelligible. The transformation and subsequent recovery of the data depend on an algorithm and zero or more encryption keys.
Digital Signature Data appended to, or a cryptographic transformation of, a data unit that allows a recipient of the data unit to prove the source and integrity of the data unit and protect against forgery (e.g., by the recipient).
Access Control A variety of mechanisms that enforce access rights to resources.
Data Integrity A variety of mechanisms used to assure the integrity of a data unit or stream of data units.
Authentication Exchange A mechanism intended to ensure the identity of an entity by means of information exchange.
Traffic Padding The insertion of bits into gaps in a data stream to frustrate traffic analysis attempts.
Routing Control Enables selection of particular physically secure routes for certain data and allows routing changes, especially when a breach of security is suspected.
Notarization The use of a trusted third party to assure certain properties of a data exchange.Encipherment The use of mathematical algorithms to transform data into a form that is not readily intelligible. The transformation and subsequent recovery of the data depend on an algorithm and zero or more encryption keys.
