Post-Quantum Resilience Gathers Pace

Post-quantum cryptography (PQC) is moving into practical identity programmes, with advances being reported on several fronts. PQC applications now range from secure element prototypes and government ID cards to federal identity credentials and national migration timetables. For identity authorities, the common issue is that credentials and trust infrastructures may remain in service for many years, making cryptographic transition a lifecycle problem rather than simply a response to the eventual arrival of a cryptographically relevant quantum computer.

Quantum-safe physical identity

Giesecke+Devrient (G+D) is developing technology for a new generation of physical identity cards under the European uPQComing project, formally 'Enhancing Cyber-Resilience for the upcoming Post-Quantum era'.

The company is working to integrate quantum-resistant cryptography into secure chips used in identity cards. The programme includes new cryptographic protocols, modifications to existing authentication mechanisms and crypto-agile architectures able to accommodate algorithm changes as standards evolve.
