Proposal on a secure communications service element (SCSE) in the OSI application layer
Kouji Nakao, Kenji Suzuki · IEEE Journal on Selected Areas in Communications · 1989
Under the increasing demand for secure communications, the existing security techniques cannot fulfil the requirements for security satisfactorily. A number of study items are identified in this area; however, one of the major targets is to realize security services in the open systems interconnection (OSI) communication environment. In response to this need, the secure communication service element (SCSE) is proposed in the OSI application layer as a new type of common application service element to provide the security services of peer-entity authentication, data confidentiality, and data integrity. As for the peer-entity authentication service, the overall authentication protocol between the peer SCSEs is proposed by using the underlying association control service element authentication procedure. Regarding the data integrity and confidentiality, the SCSE transfer service is introduced to cover all the requirements for these services to the extent of the selective field services and the recovery for integrity errors.>
