Wireless Terminal Key Management for Ad-Hoc Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing procedures for ensuring security in ad-hoc networks by verifying a connection destination's reliability are complex and require simplification.
Innovation Solution
An information processing device and wireless communication system that acquires and manages identification information and encryption keys through a network service, allowing secure communication by encrypting information with service-specific keys and decrypting them using managed decryption keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a procedure for checking whether a connection destination is a reliable partner is implemented, then security is ensured, but the procedure becomes complicated
Solution Approach 1:
The patent introduces a base station as an intermediary entity that manages encryption keys and assists in authentication. Instead of terminals directly performing complex reliability checks on each other, the base station mediates the authentication process by providing encrypted identification information and verification support, thereby ensuring security while simplifying the terminal devices' procedures
Solution Approach 2:
The patent implements preliminary key management and identification information encryption by the base station before terminal communication occurs. The base station pre-encrypts identification information with terminal-specific keys and stores them ready for authentication, so that when terminals need to verify reliability, they can use these pre-prepared encrypted identifiers without performing complex real-time encryption operations

AI summary
Security is simply and safely secured when communication is performed by an information processing device including: a communication unit configured to wirelessly communicate with another terminal; an identification information acquisition unit configured to acquire first identification information that is acquired through the communication unit and encrypted for specifying the other terminal, and that is decrypted with a first decryption key managed in a network service; and a key acquisition unit configured to acquire a first encryption key associated with the first identification information in the network service when second identification information for specifying an own terminal is associated with the first identification information in the network service. The communication unit transmits information encrypted with the acquired first encryption key to the other terminal.
