Efficient Wireless Transport Layer Security Handshake Protocol

The existing Wireless Transport Layer Security(WTLS) handshake protocol requires to exchange certificates between the client and the server,thus causes considerable communication load.And it allows client to avoid verifying the revocation state of the server certificate,which is a security flaw.In order to solve these problems,this paper proposes an improved WTLS handshake protocol based on Trusted Certificate Verification Proxy(TCVP).It only exchanges certificate identifier between the client and the server,which reduces the message payload.Moreover,TCVP is introduced to verify the online status of server certificate and seals it in a security ticket.By checking the ticket,the client is able to determine if the server certificate is valid without verifying it by itself.
