Electronic Device Authentication Reuse for Faster Service Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face inefficiencies in communication due to the need for multiple identity authentications and key negotiations when initiating multiple services, leading to prolonged communication times and reduced efficiency.
Innovation Solution
Implementing a communication method that allows electronic devices to establish a trusted relationship, enabling different authentication manners based on previous authentication status, thereby reducing the need for repeated identity authentications and key negotiations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identity authentication and key negotiation are performed for each service communication, then communication security is ensured, but communication time increases and efficiency decreases
Solution Approach 1:
The patent performs identity authentication and key negotiation in advance before actual service communication. The authentication result and session key are cached and reused for multiple services within the same communication session, avoiding repeated authentication processes. This preliminary action resolves the contradiction by ensuring security through upfront authentication while reducing communication time through key reuse.
Solution Approach 2:
The patent creates a universal authentication result that can be applied across multiple different services. Once authentication is completed, the same authentication result and session key serve multiple communication purposes (messaging, file transfer, video calls, etc.), eliminating the need for service-specific authentication and reducing overall communication time while maintaining security.
2Reliability
If identity authentication and key negotiation are performed multiple times for multiple services, then each service communication is secure, but communication efficiency decreases
Solution Approach 1:
The patent merges multiple service communications into a single authentication context. By combining multiple services under one authenticated session with a shared session key, the system ensures that each service communication remains secure while dramatically improving efficiency by eliminating redundant authentication operations across different services.
3Measurement precision
If repeated identity authentication is performed, then authentication accuracy is maintained, but time consumption increases
Solution Approach 1:
The patent creates a copy of the authentication result (session key and authentication status) that can be reused across multiple services. Instead of performing the complete authentication process repeatedly, the system copies the validated authentication data and uses it for subsequent services, maintaining authentication accuracy while reducing authentication time significantly.

AI summary
Example communication methods and apparatus are described. One example method includes determining, by a first electronic device when communicating with a second electronic device through a first application installed on the first electronic device, whether the second electronic device is authenticated by the first electronic device. If the second electronic device is not authenticated by the first electronic device, the first electronic device authenticates the second electronic device in a first authentication manner. If the second electronic device has been authenticated by the first electronic device, the first electronic device authenticates the second electronic device in a second authentication manner.
