COMPUTER UTILIZATION SYSTEM AND COMPUTER UTILIZATION METHOD FOR SECURE SESSION ESTABLISHMENT AND ENCRYPTED DATA EXCHANGE

摘要

PROBLEM TO BE SOLVED: To provide a system and method for secure session establishment and secure encrypted data exchange.SOLUTION: In the system, the session establishment is implemented in a light high-order layer such as an application layer on the basis of a cross-layer approach. Further, a session establishment result parameter including a session key is delivered to a low-order layer. The low-order layer such as a transport layer is used by the system for executing channel encryption and the encrypted data exchange can be performed based on the cross-layer approach and via a secure session.EFFECT: The system satisfies an authentication requirement of a general networking/communication system and can be easily integrated with a system which already uses a scheme such as DTLS-PSK. The low-order layer such as the transport layer is in charge of the data exchange and a transport layer recording encryption mechanism provides protection measures, such that data are protected from reflection attacks.SELECTED DRAWING: Figure 2
