Title: Santosh Kumar Mishra and 5G Subscriber Identity Protection
Introduction
Santosh Kumar Mishra is an inventor based in Pune, India. His patent work addresses secure identity handling in 5G mobile communication networks.
Latest Patents
Mishra is associated with 1 patent, titled “5G Key Generation / ECC Key Generation and SUCI Calculation.” The invention describes a method for generating a 5G subscriber concealed identifier (SUCI) within a universal integrated circuit card (UICC).
The method generates a public/private key pair, including an elliptic-curve cryptography (ECC) key pair, and derives an ephemeral shared key using Diffie–Hellman or ECDH. It then derives a symmetric encryption key and uses it to conceal at least part of the subscriber permanent identifier (SUPI), producing the SUCI. A deterministic event triggers key-pair and shared-key generation and storage in the UICC. Afterward, receipt of a GET IDENTITY command triggers derivation of the symmetric key and calculation of the SUCI.
Career Highlights
Mishra’s listed company affiliations include Giesecke+Devrient Mobile Security Germany GmbH. His patent reflects work on cryptographic key generation and subscriber-identity protection for 5G systems.
Collaborations
His listed coworkers include Ankit Pandey and Albert López.
Conclusion
Santosh Kumar Mishra’s patent describes a UICC-based approach to generating SUCIs that combines key derivation and identifier concealment to support privacy in 5G networks.
