Message Encryption With Integrated Public Key Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message transmission systems require separate servers for managing and updating public keys, leading to inefficiencies and performance deterioration in message transmission and reception.
Innovation Solution
Utilize a message server to manage and store security information, including public keys, eliminating the need for separate servers and enabling efficient encryption and decryption processes between electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate message server is used for storing and managing public keys, then security information management is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent combines the public key management function with the existing message server, eliminating the need for a separate key management server. The message server now handles both message transmission and public key storage, reducing system complexity while maintaining security.
Solution Approach 2:
The message server is extended to perform multiple functions: it serves as both a message transmission server and a public key management server. This multi-functionality reduces the number of separate components needed in the system.
2Reliability
If separate processing processes are implemented for acquiring and updating public keys, then key management is improved, but message transmission performance deteriorates
Solution Approach 1:
The patent merges the public key acquisition process with the message transmission process. When a user receives a message, the public key is automatically acquired from the message server in the same communication flow, eliminating separate processing steps and maintaining high transmission performance.
3Reliability
If public keys are stored and managed externally, then security is improved, but cost and system complexity increase
Solution Approach 1:
The patent integrates public key storage within the existing message server infrastructure, eliminating the need for external key management systems. This reduces both system complexity and deployment costs while maintaining secure key management.

AI summary
An electronic device is provided. The electronic device includes a communication module, a memory, and a server processor operably connected to the communication module and the memory. The server processor acquires, from the first electronic device, a first message encrypted based on first security information about the second electronic device, so as to transmit the first message to the second electronic device, acquires, from the second electronic device, a decryption failure signal for the first message so as to transmit the decryption failure signal to the first electronic device, acquires, from the second electronic device, second security information about the second electronic device so as to transmit same to the first electronic device, receives, from the first electronic device, a second message encrypted based on the second security information, and can transmit the received second message to the second electronic device.
