A generalized approach for the fuzzy commitment scheme
Sonam Chauhan, Ajay Kumar Sharma · Journal of Cyber Security Technology · 2019
Commitment Scheme is the way to hide the information and that information is revealed to the receiver in the later stage. The commitment scheme uses witness value to open the commitment. The role of witness value differentiates the fuzzy commitment scheme from a commitment scheme. Fuzzy commitment scheme allows the use of corrupted witness. In this paper, a generalized fuzzy commitment scheme is introduced that has the capability to reconstruct the secret from corrupted committed message and corrupted witness. The paper presents the fuzzy commitment scheme with the codes and analyzes the scheme with BCH and RS codes.
