A Forward-Secrecy WTLS Handshake Protocol Based on XTR

摘要

Because of the lack of the forward secrecy and the indefensibility from intermediator attacks and DOS attacks in WTLS, the security of current WTLS handshake protocol is far from satisfactory. In this paper we propose a new WTLS handshake protocol to solve these problems. Forward secrecy attribute has been added in the scheme, and a practicable WTLS handshake protocol has been designed on XTR system. Experiments have been taken on MSM6280 platform and the result turns out that the above security problems were efficiently solved and achieve a good performance on popular embedded platform. The conclusion can be drawn that the security and practicability of WTLS protocol has been greatly improved.
