A note on ‘An efficient certificateless aggregate signature with constant pairing computations’
Debiao He, Jianhua Chen, Miaomiao Tian
Abstract
Recently, Xiong et al. [H. Xiong, Z. Guan, Z. Chen, F. Li, An efficient certificateless aggregate signature with constant pairing computations, Information Science, 219, pp. 225–235, 2013] proposed an efficient certificateless signature (CLS) scheme and used it to construct a certificateless aggregate signature (CLAS) scheme with constant pairing computations. They also demonstrated that both of the two schemes are provably secure in the random oracle model under the computational Diffie-Hellman assumption. Unfortunately, by giving concrete attacks, we point out that Xiong et al.’s schemes are not secure in their security model.
