MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202421101331 A) filed by Tata Consultancy Services Limited on December 20, 2024, for Estimation Of Efforts In Migrating Applications To Post Quantum Cryptography (pqc) State.
Inventors include Bhowmick, Amit; Vidhani, Kumar Mansukhlal; and Alasingara Bhattachar, Rajan Mindigal.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: ABSTRACT ESTIMATION OF EFFORTS IN MIGRATING APPLICATIONS TO POST QUANTUM CRYPTOGRAPHY (PQC) STATE The ability to accurately estimate the Lines of Codes (LoC) needed to complete migration of application has been a challenge over the past decades. Embodiments disclosed herein provide a method and system for estimation of efforts in migrating applications to post quantum cryptography (PQC) state. The system, based on a determined cyclomatic complexity for one or more components present in a refined slicing output and a refined coupling output is estimated. Further, an effort of migration is estimated using the cyclomatic complexity and number of LoC impacted by the one or more cryptographic APIs. [
