Dynamic Encryption Level Adjustment for Communication Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication and data access systems lack dynamic encryption and authentication levels, making them vulnerable to security breaches, as they often maintain a single encryption level and authentication process throughout a session regardless of content or user changes.
Innovation Solution
Implement a system that uses graded authentication levels and dynamically changes encryption levels based on user authentication and content sensitivity, allowing access to encrypted data using multiple encryption types such as AES 64 and AES 128, and enabling users to change encryption levels during communication sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single encryption level is maintained throughout a communication session, then device complexity is reduced and ease of operation is improved, but security reliability deteriorates when content sensitivity changes
Solution Approach 1:
The system dynamically adjusts encryption levels during communication sessions based on content sensitivity analysis. The encryption level transitions from static to adaptive, automatically increasing when sensitive content is detected and decreasing when content becomes less sensitive, thereby maintaining high security without manual intervention.
Solution Approach 2:
The system changes the encryption parameter (encryption level) based on the sensitivity of the communication content. By analyzing content characteristics and adjusting the encryption level accordingly, the system achieves adaptive security where the encryption strength matches the content sensitivity, resolving the contradiction between security and complexity.
2Reliability
If graded authentication levels are implemented, then security reliability is improved, but device complexity and authentication process complexity increase
Solution Approach 1:
The authentication process is segmented into multiple graded levels (e.g., Level 1: basic authentication, Level 2: enhanced authentication). Each level provides progressively stronger security, allowing the system to match authentication strength to content sensitivity without requiring maximum security for all interactions, thus reducing overall complexity while maintaining high security when needed.
Solution Approach 2:
The authentication level is dynamically adjusted based on content sensitivity. The system starts with lower-level authentication for non-sensitive content and automatically escalates to higher-level authentication when sensitive content is detected, providing adaptive security that reduces complexity for routine operations while maintaining high security for sensitive operations.
3Reliability
If encryption levels are dynamically changed during communication sessions, then security is improved to match content sensitivity, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary analysis of communication content to predict sensitivity levels before full encryption/decryption operations begin. By pre-identifying sensitive content segments, the system can prepare appropriate encryption levels in advance, reducing the time penalty associated with dynamic encryption level changes.
Solution Approach 2:
The system rapidly transitions between encryption levels by skipping intermediate analysis steps when content sensitivity is clearly identifiable. For obviously sensitive content (e.g., keywords, file types), the system immediately applies appropriate encryption without exhaustive analysis, reducing processing time while maintaining security.
Data Source
AI summary
Results of an authentication process are received. The authentication process allows for a graded level of authentication using a plurality of authentication types (e.g., a username/password and a fingerprint scan). Encrypted data is then accessed. The encrypted data has been encrypted using a plurality of encryption levels. The data is unencrypted based on the graded level of authentication.In a second embodiment, a system and method are provided that establish a communication session (e.g., a voice or email communication session). The communication session is between a plurality of users. During the communication session, an indication is received to change an encryption level for the communication session. In response to receiving the indication to change the encryption level for the communication session, an encryption level of the first communication session is dynamically changed from a first level of encryption to a second level of encryption.
