USER AUTHENTICATION METHOD USING SELF-SIGNED CERTIFICATE OF WEB SERVER, CLIENT DEVICE AND ELECTRONIC DEVICE INCLUDING WEB SERVER PERFORMING THE SAME

摘要

A user authentication method using a self-signed certificate of a web server includes: receiving a log-in message generated by using a public key registered to the self-signed certificate of the web server from a client device; generating a response message by using the log-in message and a secret key corresponding to the public key; transmitting the generated response message to the client device; receiving a verification value from the client device via a secure socket layer (SSL) channel connected by using the self-signed certificate of the web server from the client device when a reliability of the response message is verified at the client device; verifying a reliability of the log-in message by using the received verification value; and confirming completion of user authentication if the reliability of the log-in message is verified.
