MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202547096644 A) filed by Mastercard International Incorporated, Purchase, U.S.A., on Oct. 7, for 'cryptographic service provision.'
Inventor(s) include Collinge, Mehdi.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "A method of providing a secure service at a computing node for a requesting party external to the computing node is described. This computing node is one of a plurality of computing nodes in a distributed computing system adapted to provide the secure service. The method comprises the following steps carried out at the computing node. A service request is received from a requesting party, wherein the service request comprises a request to generate a credential. The credential is then generated using a cryptographic key and an instance counter, wherein the cryptographic key is determined from a currently active key list of cryptographic keys for use by the computing node, wherein key lists are rotated to provide a new currently active key list at a predetermined rotation frequency, and wherein the instance counter is determined by a number of instances of performing the service within a predetermined time window. The credential is provided such that a key list reference and an instance counter value can be determined from the credential without decryption. However, the credential further comprises a key list enhancement, such that the key list enhancement is used to prevent clash between credentials having a common key list reference and a common instance counter value. A complementary method of validating such a credential is also described, together with computing apparatus adapted to perform such methods."
The patent application was internationally filed on Feb. 07, 2024, under International application No.PCT/US2024/014703.
