In this paper, we propose a Directed threshold multisignature scheme without SDC. This signature scheme is applicable when the message is sensitive to the signature receiver; and the signatures are generated by the cooperation of a number... more
Identity-based systems have the property that a user’s public key can be easily calculated from his identity by a publicly available function. The bilinear pairings, especially Tate pairings, have high performance in cryptography. With... more
We propose a robust proactive threshold signature scheme, a multisignature scheme and a blind signature scheme which work in any Gap Diffie-Hellman (GDH) group (where the Computational Diffie-Hellman problem is hard but the Decisional... more
We introduce in this paper a new identity-based threshold signature (IBTHS) technique, which is based on a pair of intractable problems, residuosity and discrete logarithm. This technique relies on two difficult problems and offers an... more
Multipath routing in Wireless Sensors Networks (WSNs) is used in order to tolerate node failures and improve the reliability of data routing. To make a multipath routing algorithm adaptive to the sensitivity of the used application,... more
It has been demonstrated by Bellare, Neven, and Namprempre (Eurocrypt 2004) that identity-based signature schemes can be constructed from any PKI-based signature scheme. In this paper we consider the following natural extension: is there... more
In this paper, we propose a Directed Threshold Multi-Signature Scheme. In this threshold signature scheme, any malicious set of signers cannot impersonate any other set of signers to forge the signatures. In case of forgery, it is... more
In a threshold RSA signature scheme, dishonest participants can disrupt signature generation by submitting junk instead of their partial signatures. A threshold signature system is robust if it allows generation of correct signatures for... more
Mobile Ad Hoc Networks (MANET), due to their lack of physical infrastructures or centralized authorities, pose a number of security challenges to a protocol designer. In particular, several typical application scenarios demand the design... more
In this paper we propose a new designated verifier signature scheme based on the threshold signature scheme presented (8) by Ghodosi and Pieprzyk. The advan- tages of the new scheme compared with previously proposed solutions are its... more
This paper develops an authentication framework for heterogeneous wireless sensor networks. We Introduce a novel concept, called k-security, in order to thwart the impact of false alerts emanating from malicious sensor nodes. The proposed... more
