Secure Wireless Communication Session ID Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure wireless communication systems face challenges in maintaining data security, particularly when user inputs like PINs are stored temporarily, leading to potential unauthorized use if devices are lost or stolen.
Innovation Solution
Implementing a secure verification approach using master and slave circuit modules that generate and validate unique session IDs for each communication session, ensuring that only matching IDs facilitate wireless communication, and invalidating IDs after a predetermined time or power event to prevent unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user input data (PIN) is stored temporarily in the portable device to facilitate communication, then communication authorization is enabled, but security risk increases due to potential unauthorized use if device is lost or stolen
Solution Approach 1:
The system generates a session ID in advance before actual communication occurs. This session ID is stored temporarily and used to authorize subsequent communications. By preparing the authorization mechanism beforehand through session ID generation, the system enables easy communication while the session ID acts as a temporary credential that doesn't expose the actual PIN
Solution Approach 2:
The session ID serves as an intermediary between the stored PIN and the communication process. Instead of using the PIN directly for communication authorization, the system introduces a session ID as a intermediate credential. This mediator allows communication to proceed without exposing the actual PIN, thereby reducing security risks while maintaining operational ease
2Reliability
If session ID is stored in memory to verify communication validity, then unauthorized use is prevented, but memory wear increases due to repeated read operations
Solution Approach 1:
The system implements periodic regeneration of session IDs based on timer events or power events. Instead of continuously reading the same session ID from memory, the system periodically updates it by generating new session IDs. This periodic action reduces repeated read operations on the same memory location, thereby reducing memory wear while maintaining security through regular credential updates
3Reliability
If session ID validation is performed for each communication attempt, then data security is maintained, but communication process complexity increases
Solution Approach 1:
The system extracts the security validation logic into a separate, dedicated session ID validation module. This extracted component handles all session ID verification operations independently from the main communication process. By separating the validation function, the system maintains data security through rigorous checking while reducing the complexity burden on the overall communication process

AI summary
Aspects of various embodiments are directed to the communication of wireless data. In a particular embodiment, an apparatus includes a master/wireless communication circuit and a slave circuit that carries out a secure function. The master generates session initiation commands, and the slave is responsive to these commands by generating and storing a session ID. In response to the receipt and validation of user-input data, the slave accesses and locally stores the session ID. Upon the initiation of and/or during a wireless communication process, the slave again accesses the session ID and compares the accessed session ID with the locally stored session ID, and facilitates communication based on the comparison (e.g., communication is not permitted if the comparison does not indicate a match).
