Researchers at the Technology Innovation Institute (TII) in Abu Dhabi, UAE, have updated six digital signature schemes for Round 2 of NIST’s Post-Quantum Cryptography Standardization process.
This initiative aims to develop cryptographic algorithms resistant to quantum computing threats. In October 2024, TII researchers collaborated with international partners. They were involved in six out of 14 selected schemes. These were chosen from an initial pool of 40 candidates. Updates submitted in February 2025 focused on design refinements that reduced signature sizes. These updates maintained security. Further optimization efforts are planned.
Updates to Digital Signature Schemes in February 2025
In February 2025, TII researchers submitted updates to six digital signature schemes under NIST‘s Post-Quantum Cryptography Standardization process. These updates focused on design refinements that reduced signature sizes while maintaining security levels. The modifications aimed to enhance performance and resilience, ensuring robust protection against potential quantum computing threats.
Dr. Najwa Aaraj, CEO of TII, emphasized the importance of this work, stating that NIST’s standardization process is a critical step in addressing future quantum computing impacts on digital security, for further details on TII’s involvement in PQC standardization.
Dr. Najwa Aaraj, CEO of TII, said: “The NIST standardization process is an important step in
addressing the future impact of quantum computing on digital security. Our research team is
actively contributing to the development of cryptographic solutions that aim to strengthen
resilience against emerging computational threats.”
