Scope and Field of Application |
This work item updates the Quantum-Safe Hierarchical Identity-Based Encryption scheme ("LATTE") described in ETSI TR 103 618 V1.1.1. The work item will incorporate improvements and implementation optimisations for the scheme, such as those made in [i.1]. It will also consider mitigations for floating point related side-channel attacks and attacks enabled by the use of a derandomised Falcon-based sampler, as described in [i.2] [i.1] Zhao, R., McCarthy, S., Steinfeld, R., Sakzad, A., & O'Neill, M. (2023). Quantum-safe HIBE: does it cost a LATTE? IEEE Transactions on Information Forensics and Security. Advance online publication. [i.2] Xiuhan Lin, Mehdi Tibouchi, Yang Yu, Shiduo Zhang. (2025).
