Electronic Certificate Expiration Control by Algorithm Imperilment Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic certificates issued with expiration dates exceeding the imperilment time of their encryption algorithms increase the risk of falsification, compromising secure network communication.
Innovation Solution
An information processing apparatus generates a key pair, creates an issue request for an electronic certificate, and controls the expiration date to prevent it from exceeding the imperilment time of the algorithm used, thereby ensuring secure network communication.

Engineering Contradiction Analysis
1Duration of action of stationary object
If the expiration date of an electronic certificate is set to a long period, then the certificate can be used for a longer time without reissuance, but the certificate may exceed the imperilment time of the encryption algorithm increasing the risk of falsification
Solution Approach 1:
The system performs preliminary determination of the imperilment time for the encryption algorithm before issuing the electronic certificate. The control unit calculates or retrieves the imperilment time based on the algorithm type and key length, then uses this information to set an appropriate expiration date that does not exceed the security threshold, preventing future security risks
Solution Approach 2:
The system dynamically adjusts the expiration date parameter of the electronic certificate based on the imperilment time parameter of the encryption algorithm. By changing the expiration date from a fixed long period to a dynamically determined value based on algorithm security characteristics, the system balances certificate usability with security requirements
2Ease of operation
If the expiration date is set by user designation without algorithm imperilment consideration, then the user has flexibility in setting the date, but the certificate may be issued with excessive expiration date exceeding algorithm security limits
Solution Approach 1:
The control unit provides feedback to the user when the designated expiration date exceeds the imperilment time of the encryption algorithm. The system compares the user-designated expiration date with the calculated imperilment time and either automatically adjusts the date or notifies the user, ensuring security requirements are met while maintaining user involvement in the process
Solution Approach 2:
The system takes preliminary anti-action by preventing the issuance of certificates with expiration dates that would exceed algorithm imperilment time. Before the certificate is issued, the control unit validates that the expiration date is within secure limits, thereby preventing potential security issues before they can occur

AI summary
An apparatus capable of preventing from setting an expiration date of an electronic certificate exceeding an imperilment time of an algorithm used for an electronic certificate issuing process. The apparatus including a memory device that stores a set of instructions, and at least one processor that executes the set of instructions to generate a key pair, generate an issue request for an electronic certificate that certifies legitimacy of the apparatus according to an instruction by a user, the issue request including a certificate signing request generated based on a public key included in the key pair, perform control to prevent a date exceeding an imperilment time of an algorithm used for an issue process for an electronic certificate from being included in the issue request as an expiration date of the electronic certificate, and obtain an electronic certificate generated according to the issue request.
