Practical verifiable random function with RKA security

Research output: Chapter in Book/Report/Conference proceedingConference PaperResearchpeer-review

Abstract

A verifiable random function (VRF) allows the generation of a random number with publicly verifiable proof, showing that the random number is honestly generated. The practical VRF used in real-world applications considers the security of uniqueness, pseudorandomness, and unpredictability under malicious key generation. In this paper, we propose the security model of related-key attack to VRF for capturing attacks like tampering attacks. We propose a new construction of VRF that satisfies the RKA security together with the existing security requirements. We implement our VRF construction and demonstrate that our scheme is practical for real-world applications.
