(2026-03) Two Decades of Identity-Based Identification Schemes- A Survey on Challenges and Advances
2026-03-23
Identity-based Identification (IBI) schemes have gained significant popularity in the field of cryptography due to their superior efficiency and scalability. However, the increasing number of proposed IBI schemes in recent years has made it challenging to compare and evaluate them effectively. To address this issue, this survey presents a comprehensive literature review and analysis of IBI schemes that offer security under various hardness assumptions. Employing a rigorous survey methodology, we introduce the first general taxonomy of IBI schemes, allowing for a systematic classification and evaluation of these schemes based on their security assumptions. Furthermore, we assess the computational and communication costs associated with the deployment of IBI schemes, considering the various challenges and limitations involved. For each class of schemes, we calculate and compare their security, efficiency, benefits, and drawbacks. Researchers and developers are actively involved in implementing and analysing the runtime of IBI, particularly in diverse applications such as mobile and IoT devices. We present implementations and provide essential insights for guiding future advancements in this dynamic field. The survey concludes by identifying current research gaps and proposing future directions for IBI schemes, providing researchers and practitioners with an in-depth understanding of the state-of-the-art in this rapidly evolving field.
