“…This study is constructed of security chameleon hash function, and further proof is in [10,11]. For example, if nodes and require mutual authentication, will first compare the preloaded chameleon hash value of the base station, CH BS , with the chameleon hash value of node , CH BS , obtained by using (1).…”

Wireless sensor networks (WSNs) contain a large number of resource-constrained and energy-limited sensor nodes that are generally deployed in an open environment. Those sensor nodes communicate with each other or with a base station via wireless channels. Therefore, secure access control is an important issue in WSNs because sensor nodes are susceptible to various malicious attacks during the authentication and key establishment phase and the new node addition phase. In this study, we propose a new access control method based on elliptic curve cryptography and the chameleon hash function. This method addresses the security problems in the existing research. It also has additional advantages since it does not require time synchronization between communication nodes, nor does it require node verification tables. In addition to our proposal, the correctness, security, resistance to possible attacks, and the performance of the proposed method are analyzed and evaluated. The results of our study demonstrate that the proposed method has an outstanding performance and fulfills all the requirements for secure communication in WSNs.

“…They mentioned that this phenomena is undesirable in applications in which the pair of collisions will be released eventually and introduced identity-based chameleon hash [37] to solve the problem. Subsequently, many novel chameleon hash schemes without the key-exposure problem were proposed such as in [38,37,39,40].…”

Secure Delegation of Signing Power from Factorization

Delegation of signing is a working way common in oce automation work, and is also an important approach to establish trust. Proxy signature is an important cryptographic primitive for delegating the signing powers and it has found many real world applications. The existing proxy signature schemes from factorization assumption are either insecure or inecient. In this paper, we propose a novel, ecient and provably secure proxy signature scheme from factorization. Our construction makes use of a factorization based key-exposure free chameleon hash function in the delegation phase and the proxy signer needs only to nd a collision to a chameleon hash value to generate a valid proxy signature. As a result, our scheme is highly ecient in terms of the computation of a proxy signature. We also provide a formal security proof by classifying the adversaries into three categories. Comparisons demonstrate that the new scheme outperforms the known ones in terms of security, computational eciency and the length of the public key.

“…Meanwhile, it disallows the creation of a valid signature if fewer than t parties participate in the protocol [3,13]. Based on the secret sharing schemes and threshold cryptosystems, Zhang [17] and Kim et al [8] proposed threshold proxy signature schemes, respectively.…”
