Title

Security Services

Control

Cryptography may be used to perform or support several basic security services: confidentiality, integrity authentication, source authentication, authorization and non- repudiation. These services may also be required to protect cryptographic keying material. In addition, there are other cryptographic and non-cryptographic mechanisms that are used to support these security services. In general, a single cryptographic mechanism may provide more than one service (e.g., the use of digital signatures can provide integrity authentication, and source authentication), but not all services.
