Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peer-to-peer authentication systems require mobile devices to register with a third-party platform, lacking a standardized authentication system.
Innovation Solution
A system and method enabling peer-to-peer authentication between mobile devices associated with wireless telecommunication networks without requiring registration with a third-party platform, using cryptographic key exchange and international mobile subscriber identity (IMSI) validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices register with a third-party platform for authentication, then authentication can be performed, but device complexity and dependency on external services increase
Solution Approach 1:
The patent implements self-service authentication by enabling mobile devices to authenticate directly with each other using their own cryptographic credentials (public keys and IMSI) without requiring registration or intervention from third-party platforms. Each device serves its own authentication needs through peer-to-peer verification.
Solution Approach 2:
The patent extracts the authentication function from third-party platforms and implements it directly within the mobile devices themselves. By removing the external authentication service dependency, the system achieves standalone authentication capability using built-in cryptographic modules and cellular network credentials.
2Reliability
If third-party platforms are used for authentication, then authentication is enabled, but verification time increases
Solution Approach 1:
The patent skips the time-consuming registration and intermediary verification steps by implementing direct peer-to-peer authentication. Devices exchange cryptographic credentials and verify each other immediately through cellular network authentication mechanisms, rushing through the authentication process without intermediate delays.
Solution Approach 2:
The patent utilizes preliminary action by leveraging pre-existing cryptographic credentials (public keys and IMSI) that are already configured in each mobile device before authentication is needed. These credentials are prepared in advance through device provisioning and cellular network registration, enabling immediate authentication without real-time setup.
3Adaptability or versatility
If standardized authentication system is implemented, then peer-to-peer authentication is enabled, but network coverage is limited
Solution Approach 1:
The patent achieves universality by implementing an authentication mechanism that works across different cellular networks and wireless standards. The peer-to-peer authentication using cryptographic credentials and IMSI verification is network-agnostic, allowing devices to authenticate regardless of which cellular network they are connected to, thereby extending coverage beyond single-network limitations.
Solution Approach 2:
The patent uses the cellular network as an intermediary for credential verification rather than requiring direct device-to-device communication for authentication. The cellular network acts as a trusted mediator that verifies IMSI credentials, enabling authentication even when devices are not in direct range, thus extending the effective coverage area.

AI summary
A first UE can receive a request to communicate from a second UE. The first UE and the second UE can exchange a first cryptographic key and a second cryptographic key associated with the first and the second UE, respectively. The first UE can receive an encrypted unique identifier associated with the second UE, where the unique identifier identifies a second wireless telecommunication network serving the second UE. The first UE can authenticate the second UE by sending the encrypted unique identifier to a first wireless telecommunication network and sending a request to confirm that the unique identifier is valid. The first UE can receive, from the first wireless telecommunication network, a confirmation that the unique identifier is valid. Upon receiving the confirmation, the first UE can engage in a communication with the second UE.
