This paper presents a secure constant-round password-based group key exchange protocol in the common reference string model. Our protocol is based on the group key exchange protoco...
We present a hash-based signature scheme customized for wireless sensor networks. For message lengths required by instructions or queries from the base station or single measuremen...
The goal of a Public-Key-Infrastructure (PKI) is to prove whether a cryptographic public key is authentic for a certain user. This information is crucial for the reliability of as...
Abstract. Anti-spoofing protection of biometric systems is always a serious issue in real-life applications of an automatic personal verification system. Despite the fact that face...
Abstract. Signcryption is a public-key cryptographic primitive introduced by Zheng, which achieves both message confidentiality and nonrepudiatable origin authenticity, at a lower ...
