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 ...

Cryptanalysis on Two Certificateless Signature Schemes
International Journal of Computers Communications & Control, 2010 Certificateless cryptography has attracted a lot of attention from the research community, due to its applicability in information security. In this paper, we analyze two recently proposed certificateless signature schemes and point out their security flaws.

Efficient and Short Certificateless Signature
, 2008 A certificateless signature (CLS) scheme with short signature size is proposed in this paper. Our scheme is as efficient as BLS short signature scheme in both communication and computation, and therefore turns out to be more efficient than other CLS schemes proposed so far.

Certificateless Proxy Signature from RSA [PDF]
Mathematical Problems in Engineering, 2014 Although some good results were achieved in speeding up the computation of pairing function in recent years, it is still interesting to design efficient cryptosystems with less bilinear pairing operation. A proxy signature scheme allows a proxy signer to sign messages on behalf of an original signer within a given context.

Insecurity of a Certificateless Aggregate Signature Scheme [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2016 AbstractAs an important kind of digital signature, the aggregate signature could aggregate n signatures into a signature and verify those signatures simultaneously. It is suitable for the constrained environment with limited ability of computation and communication. Recently, Chen et al.
