Programmable Device Secure Access via Session Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for restoring access to programmable devices when users forget or lose their authentication credentials are insecure, as they often rely on factory resets, backdoor passwords, or other methods that compromise device security.
Innovation Solution
A system and method that uses a programmable device with a processor to decode authentication credentials, generate session identifiers, and grant access only if the identifier matches a stored authentication session, while implementing timers and access failure thresholds to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If factory reset or backdoor password methods are used to restore access, then users can regain access to their devices, but device security is compromised
Solution Approach 1:
The system performs preliminary actions by generating time-limited authentication credentials before the user loses access. These credentials are generated with embedded expiration timers and session identifiers that validate the credential's temporal validity, allowing users to regain access without compromising device security through traditional backdoor methods
Solution Approach 2:
The invention changes the parameter of authentication credentials from static (permanent passwords) to dynamic (time-limited credentials with expiration timestamps). The credential includes a session identifier and timing information that the processor validates to determine whether the credential is within its valid time window, thus providing secure temporary access
2Reliability
If time-limited authentication credentials are implemented, then device security is maintained, but system complexity increases
Solution Approach 1:
The authentication credential is segmented into distinct components: a session identifier, a timestamp indicating validity period, and an encrypted authentication token. The processor separately validates each component - checking session match, verifying time window validity, and decrypting the token - which distributes the complexity across multiple simple validation steps rather than one complex verification process

AI summary
According to various aspects and embodiments, a system including a programmable device is provided. The programmable device includes a memory storing an identifier of an authentication session and at least one processor coupled to the memory. The at least one processor is configured to receive an authentication credential, decode the authentication credential to access a session identifier and information associated with a requestor of the authentication credential, determine whether the session identifier matches the identifier of the authentication session, and grant the requestor access to protected functionality of the programmable device if the session identifier matches the identifier of the authentication session.
