ID-CEPPA: Identity-based Computationally Efficient Privacy-Preserving Authentication scheme for vehicle-to-vehicle communications

An Efficient Authentication Protocol Based on Chebyshev Chaotic Map for Intelligent Transportation

“…However, it is found that the protocol is mainly depended on the advanced encryption standard (AES), which increases the system complexity and limits the ability of VANET to meet its high mobility demands. The proposed protocol in [13] achieves the vehicle anonymity feature without using bilinear pairing processes, but it mainly relies on elliptic curve cryptography (EEC) that has a negative effect on the system implementation.…”

“…More specifically, it is found that the schemes [9], [12], and [14] rely on complex bilinear operations. Despite a fuzzy extractor technique is used to protect biometric templates in the schemes [10] and [11], the elliptic curve cryptography (EEC) adds a complexity in the implementation of the scheme [13]. Although lightweight operations such as the Chebyshev chaotic maps are used in the scheme [15], excessive authentication procedures are performed to accomplish the authentication between the vehicle and the RSU due to the complete reliance on the central TA.…”

“…Let the term x be the sum result. With the help of the Chebyshev chaotic map, the formula of 𝑆 𝑗 can be constructed using x, the RSU private key 𝑢 𝑗 , and the security parameter SP 3 as shown in (13).…”

“…𝑆 𝑗 = T 𝑔 𝑥 + 𝑢 𝑗 − SP 3 (𝜂) mod 𝑃 (13) Accordingly, the RSU broadcasts the message 𝑀 1 = {OID j , 𝑡 1 , 𝐿 𝑗 , 𝑈 𝑗 , 𝐶 𝑗 , 𝑆 𝑗 } over a wireless channel.…”

“…As shown in Fig. 4, although the scheme [13] has the fewest number of tools, it is heavily based on cryptographic hash functions. Also, the scheme [9] has the highest tools.…”
