New Cryptographic Method Based on Sudoku Puzzle Enhances Data Security
In recent years, cybersecurity has become an increasingly important aspect of life, and the latest progress in this area promises to increase data security. The International Information and Computer Security Journal discusses a new cryptographic method based on the Japanese puzzle of Sudoku. This method is suitable even in situations with limited computing power and can find application in devices such as RFID, medical equipment, remote networks, and smart cards.
A team of scientists from Jordan and Iraq has demonstrated how the dynamic nature of the Sudoku puzzle can serve as the foundation for a secret encryption key. This approach significantly enhances system security and, based on experimental results, surpasses other lightweight cryptography methods.
The newly developed algorithm, called “Message Encryption (Inspired by) Sudoku Puzzle” (Mesp), boasts an extensive key space and offers superior frequency analysis compared to alternative methods. The system allows for expansion of index tables to accommodate all possible characters in different languages, providing robust protection against security breaches.
The fusion of ideas from the Sudoku puzzle, pseudo-random number generation, and dynamic rearrangement enables the creation of a powerful security tool that will have applications in various fields. Researchers believe that their algorithm promises to usher in a new era in lightweight cryptography.
