MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202521047630 A) filed by Dr. Dattatray Nabajirao Shinde; Dr. Machchhindra Tolaji Gophane; and Mr. Yogesh Nabaji Shinde, Satara, Maharashtra, on May 17, 2025, for 'method and system for generating public and private keys using semigroups.'
Inventor(s) include Dr. Dattatray Nabajirao Shinde; Dr. Machchhindra Tolaji Gophane; and Mr. Yogesh Nabaji Shinde.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a novel cryptographic method for generating public key 3 and private key 4 using semigroups 1, specifically ternary and partially ordered ternary semigroups. Traditional cryptographic systems rely on number theory, which is vulnerable to quantum attacks. This system leverages the algebraic properties of semigroups 1 such as non-commutativity, non-invertibility, and associativity to ensure strong security and computational irreversibility. The private key 4 is selected from a complex semigroup 1 structure, while the public key 3 is generated using semigroup 1 operations with public elements. The resulting public key 3 is safe to distribute and cannot be reverse-engineered to reveal the private key 4. This method supports ternary operations, pseudo-symmetric ideals, and bi-ideals for enhanced cryptographic strength. It is suitable for a range of applications, including secure communications, digital signatures, and post-quantum cryptographic systems."
