AUTHENTICATION SYSTEM AND AUTHENTICATION APPARATUS FOR AUTHENTICATING AUTHENTICATION-TARGET APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18340683 Titled 'AUTHENTICATION SYSTEM AND AUTHENTICATION APPARATUS FOR AUTHENTICATING AUTHENTICATION-TARGET APPARATUS'
Simplified Explanation
The abstract describes an authentication system that verifies the identity of a target. The system works by sending a code and a challenge to the target, which then generates a password through repetitive computation using the code as input. The target then compares this password with a pre-stored password for authentication. If the authentication is successful, the target retrieves an authentication seed based on the number of times the computation was executed. Using this seed and the challenge, the target generates a response and sends it back to the authentication system.
Original Abstract Submitted
An authentication apparatus transmits code and challenge to a target, receives a response, and authenticates the target based on the response. The target receives the code and the challenge, generates a password for comparison by executing n times of repetitive computation by a recurrence relation or a recursive function using the code as an initial input, executes password authentication using a pre-stored password and the password for comparison. If the password authentication has succeeded, the target reads out an authentication seed corresponding to the number n that is the number of times of execution of the repetitive computation with which the password for comparison that matches a password has been obtained, and generates the response using the read-out authentication seed and the challenge received from the authentication apparatus, and transmits the response.
