Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic messaging systems face risks of interception and exposure due to the numerous intermediary devices messages pass through, compromising security and privacy.
Innovation Solution
A secure communication kit utilizing a set of tangible security tokens, each storing cryptographic keys and a group identifier, which can form symmetric or asymmetric key pairs, and a client device to encrypt and decrypt messages using these keys, ensuring secure communication across a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If messages pass through numerous intermediary devices (servers, gateways, switches, routers) to enable long-distance electronic messaging, then communication reach and connectivity are improved, but security and privacy are compromised due to increased risk of interception and exposure
Solution Approach 1:
The patent introduces security tokens as intermediary devices that mediate between the message and the communication channels. These tokens contain cryptographic keys and group identifiers that enable secure encryption and decryption at each intermediary stage, transforming the harmful effect of multiple intermediaries into a protective mechanism where each intermediary can verify authenticity without compromising security.
Solution Approach 2:
The patent applies preliminary action by pre-distributing security tokens to authorized participants before communication begins. Each token is pre-configured with cryptographic keys and group identifiers, allowing participants to immediately encrypt messages upon receiving them without requiring real-time key exchange or authentication protocols during the actual communication.
2Reliability
If security tokens store cryptographic keys and group identifiers to enable secure message encryption and decryption, then message security is improved, but device complexity increases due to the need for key management and cryptographic operations
Solution Approach 1:
The patent segments the security system into distributed security tokens, with each token containing a portion of the cryptographic infrastructure (specific keys and group identifiers). This segmentation eliminates the need for centralized key management, as each participant independently manages their own token without requiring coordination with other participants or a central authority.
Solution Approach 2:
The security tokens are designed to be self-sufficient, containing all necessary cryptographic material (cryptographic keys and group identifiers) required for encryption and decryption operations. Each token autonomously performs cryptographic operations without requiring external key management infrastructure, reducing overall system complexity while maintaining high security.
Data Source
AI summary
A secure communication kit is disclosed. The secure communication kit may include a plurality of tangible security tokens; each security token storing one or more cryptographic keys and a group identifier. A first cryptographic key stored on each security token may correspond to one of the cryptographic key(s) stored on every of the other security tokens. The group identifier stored on each security token may correspond to each group identifier stored on every of the other security tokens. A client device for securely communicating using the secure communication kit is also disclosed.
