“…is scheme proposed a secure method against A I and A I I in the random oracle model [23]. At the end of 2014, several researchers have proposed CLS scheme without utilizing any pairing to increase the efficiency, but the signature length is very large which cannot constraint the unlimited bandwidth and storage devices in VANET [122,123]. In the year 2015, a new scheme of V2I communication based on certificateless signature is introduced.…”

Recently, vehicular ad hoc networks (VANETs) embark a great deal of attention in the area of wireless and communication technology and are becoming one of the prominent research areas in the intelligent transportation system (ITS) because they provide safety and precautionary measures to the drivers and passengers, respectively. VANETs are quite different from the mobile ad hoc networks (MANETs) in terms of characteristics, challenges, system architecture, and their application. In this paper, we summarize the recent state-of-the-art methods of VANETs by discussing their architecture, security, and challenges. Secondly, we discuss the detailed analysis of security schemes and the possible measures to provide secure communication in VANETs. Then, we comprehensively cover the authentication schemes, which is able to protect the vehicular network from malicious nodes and fake messages. Thus, it provides security in VANETs. Thirdly, we cover the mobility and network simulators, as well as other simulation tools, followed by the performance of authentication schemes. Finally, we discuss the comfort and safety applications of VANETs. In sum, this paper comprehensively covers the entire VANET system and its applications by filling the gaps of existing surveys and incorporating the latest trends in VANETs.

“…While the elimination of pairing operations [10] hasn't been fully realized in ABS yet, however, in identity based cryptography and certificateless public cryptography, some researchers have successfully construct their schemes [13][14][15][16] without pairings. Ibrahim Elashry et al in [13] proposed an efficient identity based encryption scheme independent of pairings.…”

Abstract. Attribute based signature (ABS) is a significant cryptographic notion providing secure authentication during data sharing. A signer can sign a message using the private keys he processes. However, user's private key exposure may happen from time to time and this will bring potential threat to the whole system. Thus, key evolving mechanism should be introduced into ABS schemes. Besides, the efficiency of existing ABS schemes can be further improved since the process of signing and verification require massive bilinear pairings, which occupies costly computing resources on mobile terminal devices. To better tackle the above problems and provides a more secure data authentication method in mobile communication systems, in this paper, we firstly propose a key insulated attribute based signature scheme without pairings (KI-ABS-WP). Then we give the formalized definition as well as the concreted constructions of our scheme. In our KI-ABS-WP, uses needn't run any bilinear pairings, thus the total computation cost has been reduced to a large extent. If key exposure occurs, key insulation mechanism guarantees system's both backward and forward security. Finally, by performance analysis, our KI-ABS-WP is shown to be suitable for data authentication in wireless communications.

“…Gong and Li [24] pointed out the new scheme is insecure against the super adversary in the random oracle model, and they proposed a real CLS scheme and demonstrated that their scheme is secure against the supper adversary. Yeh et al [25] proposed a secure certificateless signature scheme without pairings in 2014. In this paper, we propose a new CLS scheme without bilinear pairings, and is provable secure in the random oracle model (ROM) under the discrete logarithm assumption.…”

Since certificateless public key cryptosystem can solve the complex certificate management problem in the traditional public key cryptosystem and the key escrow problem in identity-based cryptosystem and the pairing computation is slower than scalar multiplication over the elliptic curve, how to design certificateless signature (CLS) scheme without bilinear pairings is a challenge. In this paper, we first propose a new pairing-free CLS scheme, and then the security proof is presented in the random oracle model (ROM) under the discrete logarithm assumption. The proposed scheme is more efficient than the previous CLS schemes in terms of computation and communication costs and is more suitable for the applications of low-bandwidth environments.
