First, is authentication service, which defines as the assurance that the communicator is legitimate and is the one that it claims to be. It can either be peer entity or data origin authentication.

Data confifentiality: the protection of data from unauthorized disclosure. Data integrity: the assurance that data received are exactly as sent by an authorized entity (e.t.c, contain no modificafion, insertion, deletion, or replay).
