Cryptanalysis of a certificateless aggregate signature scheme [PDF]
IACR Cryptol. ePrint Arch., 2016 Recently, Nie et al. proposed a certificateless aggregate signature scheme. In the standard security model considered in certificateless cryptography, we are dealing with two types of adversaries. In this paper, we show that Nie et al.'s scheme is insecure against the adversary of the first type. In other words, although they claimed that their ...

Identity-based key-insulated aggregate signature scheme
Journal of King Saud University: Computer and Information Sciences, 2017 Private key exposure can be the most devastating attack on cryptographic schemes; as such exposure leads to the breakage of security of the scheme as a whole. In the real world scenario, this problem is perhaps the biggest threat to cryptography.
