Mobile Payment Encryption Using Quantum Random OTP and SHA-3 Hashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile payment systems using public key cryptography are vulnerable to quantum computers and lack integrity protection against data tampering, as traditional One-Time Pad cryptography does not ensure data integrity during transmission.
Innovation Solution
A processor-implemented method using a one-time pad (OTP) key generated from true random numbers, where payment data is encrypted and a hash value is generated and concatenated with the data, then encrypted using the OTP key, ensuring both integrity and validity verification through Secure Hash Algorithm-3 (SHA-3) and OTP encryption, preventing tampering and replay attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If public key cryptography is used for mobile payment encryption, then security against classical computers is improved, but vulnerability to quantum computer attacks increases
Solution Approach 1:
The patent changes the fundamental parameter of cryptographic security from computational hardness (public key cryptography) to information-theoretic security (one-time pad). By transitioning to true random number generation and single-use encryption keys, the system achieves security that is independent of computational power, making it resistant to quantum computer attacks while maintaining security against classical computers.
2Reliability
If traditional One-Time Pad cryptography is used for encryption, then perfect secrecy against eavesdropping is improved, but protection against data tampering worsens
Solution Approach 1:
The patent merges two previously separate cryptographic functions into a unified system: one-time pad encryption for confidentiality and hash function verification for integrity. By concatenating the original message with its hash value and encrypting the combined data with OTP, the system simultaneously achieves perfect secrecy and tamper detection, resolving the contradiction between eavesdropping protection and data integrity.
