Secure Time-to-Live Message Access via External Master Clock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing approaches to securing electronic communications are cumbersome and susceptible to interception, eavesdropping, and forensic analysis, lacking in ease of use and effectiveness.
Innovation Solution
A digital security bubble (DSB) platform that encapsulates encryption information and message security controls, allowing secure communication across multiple recipients and platforms, using public/private keypairs and hardware binding for secure message transmission, with features like forward secret messaging and time-to-live controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital certificates or keys are used to secure communications, then security is improved, but ease of operation deteriorates due to tedious management
Solution Approach 1:
The system automatically performs certificate management, key generation, and security operations without requiring user intervention. The server handles certificate issuance, renewal, and revocation automatically, while clients automatically manage their key pairs and security credentials, eliminating the tedious manual management of digital certificates and keys.
2Reliability
If existing security approaches are used, then encryption is provided, but susceptibility to interception and eavesdropping worsens
Solution Approach 1:
The system performs preliminary security setup by establishing secure channels and exchanging cryptographic credentials before actual communication begins. The server pre-generates and distributes security credentials to clients, and secure sessions are established in advance, preventing interception and eavesdropping during the communication process.
3Reliability
If digital security measures are implemented, then message security is improved, but device complexity worsens
Solution Approach 1:
The server acts as an intermediary that centralizes security management functions. Instead of each device implementing complex security protocols independently, the server handles certificate issuance, key management, and security policy enforcement, simplifying the client devices while maintaining strong message security through centralized control.
Data Source
AI summary
Determining whether to allow access to a message is disclosed. A message is received from a sender. The message is associated with a first time-to-live (TTL) value. A determination is made that the first time-to-live value has not been exceeded. The determination is made at least in part by obtaining an external master clock time. In response to the determination, access is allowed to the message.
