Secure Unlock Password Distribution via Segmented Trust Entities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating and distributing unlock passwords for communication devices are insecure, as they are not adequately protected, leading to unauthorized access by attackers.
Innovation Solution
A process is implemented where exclusive responsibilities are assigned to different entities for random generation, encryption, digital signing, and verification of unlock passwords, ensuring secure distribution and authentication, including a trusted authority, security agent, and password processing center, with each entity having specific and separate responsibilities to prevent compromise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unlock passwords are generated, stored, and distributed using current methods, then the process is simple and fast, but the security is insufficient allowing unauthorized access
Solution Approach 1:
The patent segments the password management system into three distinct entities with exclusive responsibilities: a trusted authority that generates and encrypts passwords, a security agent that signs and distributes passwords to devices, and a password processing center that stores and verifies passwords. This segmentation isolates security-critical functions across multiple trusted components, preventing single-point compromise and enhancing overall system security despite increased architectural complexity.
2Reliability
If a single entity manages the entire password process, then the process is simple, but a compromise of that entity leads to complete security failure
Solution Approach 1:
The system divides password management responsibilities among three separate entities: trusted authority (generation and encryption), security agent (signing and distribution), and password processing center (storage and verification). This segmentation ensures that compromise of any single entity does not result in complete system failure, as each entity has limited exclusive responsibilities that cannot be fulfilled alone.
Solution Approach 2:
The patent implements beforehand cushioning by requiring multiple layers of cryptographic protection (encryption by trusted authority, digital signing by security agent, and verification by password processing center) before passwords are distributed. This pre-established multi-layer security architecture cushions against potential compromises at any single point in the system.

AI summary
A process may be utilized for securing unlock password generation and distribution. A first set of exclusive responsibilities, assigned to a trusted authority, includes random generation and encryption of an unlock password to compose a randomly generated encrypted unlock password. Further, a second set of exclusive responsibilities, assigned to a security agent, includes sending information associated with the unlock password and a digital signature of information associated with the unlock password to a communication device configured for a network in order to mate the unlock password to the communication device, and sending the randomly generated and encrypted unlock password along with mating data to a password processing center. In addition, a third set of exclusive responsibilities, assigned to a password processing center, includes decrypting the randomly generated and encrypted unlock password.
