Intellectual Property India Publishes Patent Application for 'Pairwise Key Establishment Between Two Measurement States' Filed by Qualcomm Incorporated

MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202547068075 A) filed by Qualcomm Incorporated, San Diego, on July 16, for 'pairwise key establishment between two measurement states.'

Inventor(s) include Kannisto Joona Verneri; and Brahma Aseem.

The application for the patent was published on July 25, under issue no. 30/2025.

According to the abstract released by the Intellectual Property India: "Systems and techniques are described for key establishment. For instance, a process can, during a first cryptographic key derivation, store a first trusted measurement value of a first entity in a first storage location, store an expected measurement value of a second entity in a second storage location, and generate a first instance of a cryptographic key using the first trusted measurement value, the expected measurement value, and a key derivation function (KDF). The process can, during a second cryptographic key derivation, obtain the expected measurement value as a second trusted measurement value of the second entity and store it in the second storage location, obtain the first trusted measurement value as a second expected measurement value and store it in the first storage location, and generate a second instance of the cryptographic key using the second expected measurement value, the second trusted measurement value, and the key derivation function."

The patent application was internationally filed on Mar. 12, 2024, under International application No.PCT/US2024/019542.
