“…However, now scholars are embracing it in wireless system promptly. In 2017, Wei, Yang, and Mu presented the idea of a proxy re‐signature plan for wireless networks where the proxy can be reformed into the appointed affirmer whenever required [16]. This idea was beneficial for anonymous authentication.…”

“…The concept of SDVS was first introduced by Jakobsson et al [7], and formalized by Saeednia et al [21]. Since then, some efficient SDVS schemes were proposed [22][23][24][25][26][27], but the security of those schemes is based on the ideal random oracle. To deal with this problem, Hung et al [17] designed a SDVS scheme in the standard model.…”

Strong designated verifier signature can provide an efficient way to protect the identity privacy of the signer and the integrity of the data transmitted over the public channel. These characteristics make it very useful in outsourcing computing, electronic voting, electronic bidding, electronic auction and other fields. However, most strong designated verifier signature schemes are unable to identify the real signature generator when the signer and the designated verifier dispute a signature. In addition, the existing strong designated verifier signature schemes in the standard model rarely satisfy strong unforgeability, and thus cannot prevent the attacker from forging a valid signature on any previously signed message. Therefore, designing a strong designated verifier signature scheme without random oracles that satisfies strong unforgeability and undeniability is very attractive in both practice and theory. Motivated by these concerns, we design the first undeniable strong designated verifier signature scheme without random oracles, in which the arbiter can independently perform the judgment procedure to prove whether a controversial signature is generated by the signer or the designated verifier. Under standard assumptions, the scheme is proved to be strongly unforgeable in standard model. Furthermore, it not only achieves non-transferability and privacy of the signer’s identity but also satisfies the undeniable property of traditional digital signature schemes. Performance analysis results show that the length of the signer’s private key, the designated verifier’s private key and signature length are 40 bits, 40 bits and 384 bits, respectively. Compared with he related schemes, the proposed scheme has higher performance in signature length, private key size and computational overhead. Finally, we show how to apply it to implement outsourcing computation in cloud computing.

“…The researchers also proposed some variants of DVS such as universal DVS [50,51] and multi-verifier DVS [52,53]. Until now, the only DVPRS scheme was that proposed by Wei et al [14], but its security was dependent on ideal random oracles.…”

“…However, anyone can use the signer's public key to verify the validity of the signature, so with concrete hash functions [18]. In fact, Wei et al's proposal [14] is an SDVPRS scheme since the verification of the signature requires the designated verifier's secret key. Therefore, constructing a secure (S)DVPRS scheme without random oracles in the standard model is an unsolved problem.…”

A Strong Designated Verifier Proxy Re-Signature Scheme for IoT Environments

et al. 2018

With the rapid popularization of the Internet of Things (IoT) in our daily lives, the communication security and identity privacy of IoT devices must be ensured. However, traditional authentication mechanisms utilized in IoT cannot completely ensure a user’s privacy when his/her messages are routed via an untrusted intermediate device. Strong designated-verifier proxy re-signature (SDVPRS) is a new cryptographic technology that combines the advantages of strong designated verifier signature and proxy re-signature. Therefore, SDVPRS is considered to be a better approach to maintain data integrity and protect the identity privacy of the signer in a resource-limited IoT device. Nevertheless, designing a secure SDVPRS scheme without random oracles is still a challenging task. In this paper, we mainly focus on such a construction by providing a new method. We first provide the formal definition of SDVPRS and its security model. Then, we present the first SDVPRS scheme, which is bidirectional, multi-use and non-transferable, and we prove its security under the standard complexity assumptions in the standard model. The analysis results show that our SDVPRS scheme can not only protect the privacy of the signer’s identity, but also provide non-delegatability for signature verification. We present an example of potential application to environmental monitoring systems using our SDVPRS scheme.
