Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cryptographic techniques, such as those relying on asymmetric mathematical problems, may become vulnerable to advances in technology, necessitating the development of stronger cryptographic methods to maintain data security, especially in protecting sensitive information like financial and medical data.
Innovation Solution
The implementation of implicit certificates using Ring Learning With Errors (RLWE) public keys, which are resistant to quantum-based computing attacks, enables secure communication by generating and verifying cryptographic key pairs through a Certificate Authority (CA), ensuring the authenticity of public keys and verifying access to private keys during key usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional asymmetric cryptographic techniques are used, then current data security requirements are met, but the system becomes vulnerable to quantum-based computing attacks
Solution Approach 1:
The patent changes the fundamental mathematical parameters of the cryptographic system by transitioning from traditional asymmetric cryptography to Ring Learning With Errors (RLWE) based implicit certificates. This parameter change enables resistance to quantum attacks while maintaining certificate functionality through a different mathematical foundation (lattice-based cryptography instead of factoring or discrete logarithm problems).
Solution Approach 2:
The patent substitutes the mechanical/mathematical system of traditional certificate verification with an implicit certificate system based on RLWE. Instead of explicit digital signatures and certificate chains, the system uses implicit cryptographic relationships where the certificate is embedded in the key generation process itself, reducing verification complexity while enhancing quantum resistance.
2Reliability
If traditional digital certificates are used, then identity verification is achieved, but computational resources are consumed
Solution Approach 1:
The patent extracts the certificate verification process from the traditional explicit model and embeds it implicitly in the key generation and authentication process. The implicit certificate contains the verification information within the cryptographic keys themselves, eliminating the need for separate certificate transmission and verification operations, thus reducing computational overhead while maintaining identity verification reliability.
3Reliability
If stronger cryptographic techniques are developed, then resistance to quantum attacks is achieved, but implementation complexity increases
Solution Approach 1:
The patent creates a universal implicit certificate system based on RLWE that serves multiple functions: it provides quantum-resistant cryptography, enables identity verification, and simplifies key management. The RLWE-based implicit certificate framework is designed to be broadly applicable across different cryptographic operations and systems, making implementation easier through standardization and multi-functionality rather than requiring separate specialized components for each cryptographic need.

AI summary
An implicit certificate is based on a ring learning with errors (“RLWE”) public keys that are, in some examples, resistant to quantum-based computing attacks. Various methods are described that request, generate, verify, and use the implicit certificates. In some examples, the system provides an implicit certificate that enables communication between two parties that are identified at the time of certificate generation. In another example, the system provides a certificate that may be used to communicate with a variety of different parties. The implicit certificate generation algorithm yields a public key purportedly bound to U. Confirmation that the public key is bound to U is obtained after use of the corresponding private key. Binding of an entity to its associated public key and accessibility to the private key, are verified as a result of successful key use.
