TERMINAL AUTHENTICATION SYSTEM AND TERMINAL AUTHENTICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a terminal authentication system capable of using implementation means over a wide range as device physical information generation means and suppressing a frequency of implementation of a registration phase.SOLUTION: A terminal 160 includes: device physical information generation means 480 for generating physical information relating to components of the terminal 160 as device physical information; public key encryption means 411 for encrypting the device physical information and transmitting it to a server 150; terminal-side key generation means 433 for generating terminal-side random information using the device physical information; and terminal-side key verification means 473. The server 150 includes: public key decryption means 410 for decrypting the encrypted device physical information; physical information storage means 450 for storing the device physical information; server-side key generation means 432 for generating server-side random information using the device physical information; collation means 460 for collating the terminal 160; and server-side key verification means 472.
