Abstract The authors have proposed a secure communications service element (SCSE) which can provide such security functions as authentification, information confidentiality, and data integrity (prevention of data modification), as application service elements (ASE) in the open‐type system interconnection(OSI) application layer. The proposal is evaluated highly from the viewpoint of OSI protocol design technique to realize the security function. This paper attempts to verify the realizability of the proposed SCSE and the applicability to OSI communication. Further, it reports on the design of the SCSE software package and the implementation/evaluation. In the implementation/evaluation of the proposed package, especially, it is intended to demonstrate the applicability to OSI communication applications. As typical examples of SCSE applications, file transfer access and management (FTAM) assuming the totally duplicate communication function in the session layer, as well as document transfer and manipulation (DTAM) assuming the use of the semiduplicate communication function are adopted. Through the verification experiment such as the measurement of the processing load, the practical usefulness and the applicability of SCSE are evaluated. As a result, it is shown that the efficient OSI security communication system can be realized by SCSE. Since the proposed approach can be applied to the totally duplicate and the semiduplicate communications, it is shown that the method is applicable to all OSI communication applications.
