The fuzzy vault scheme aims to secure user's critical data (secret encryption key) with the fingerprint data in a way that only the legitimate user is able to access the key by providing his fingerprint. The existing fuzzy vaults constructions are mainly based on techniques which require a pre-alignment phase of template biometric sample and the query one.(More)
Oblivious transfer protocol is an important cryptographic primitive having numerous applications and particularly playing an essential role in secure multiparty computation protocols. On the other hand existing oblivious transfer protocols are based on computational-ly expensive public-key operations which remains the main obstacle for employing such(More)
We discuss the protection of Gaussian biometric templates. We first introduce the Juels-Wattenberg for binary biometrics, where the binary biometrics are a result of hard-quantized Gaussian biometrics. The Juels-Wattenberg scheme adds a random binary code word to the biometric for privacy reasons and to allow errors in the biometric at authentication. We(More)
The contribution of this paper is twofold. First we present a new simple electronic voting scheme having standard re-encryption mix net back-end, which allows to cast a ballot and verify its correctness in a new way. Then we extend the proposed scheme to represent a new very efficient mix network construction. We called our mix network to be self-proving(More)
In this paper we describe an efficient protocol for oblivious evaluation of a binary alphabet Deterministic Finite Automata (DFA) between the DFA owner (client) and the input text owner (server). The protocol requires only a single round of client-server communication. The number of server-side computations is linear to the text length and does not depend(More)
