In this paper, the authors propose a new structured multisignature scheme that considers the signing order among co-signers. The proposed scheme can resolve signing structures of serial, parallel, and the mix of them. Moreover, the size and the verification of a structured multisignature is the same as those of an individual signature generated by any(More)
Proxy signatures are very useful tools when one needs to delegate his/her signing capability to other party. After Mambo et al.'s first scheme was announced, many proxy signature schemes and various types of proxy signature schemes have been proposed. Due to the various applications of the bilinear pairings in cryptography, there are many ID-based signature(More)
At the conference Asiacrypt 2001, Rivest, Shamir and Tauman firstly addressed the concept of ring signature. We propose an identity-based ring signature scheme from bilinear pairings. As compared with the Zhang-Kim scheme (presented at the conference Asiacrypt 2002), our scheme is more efficient in computation and requires fewer pairing operations.

Control of ribosome biogenesis is a potential mechanism for the regulation of cell size during growth, and a key step in regulating ribosome production is ribosomal RNA synthesis by RNA polymerase I (Pol I). In humans, Pol I transcription requires the upstream binding factor UBF and the selectivity factor SL1 to assemble coordinately on the promoter. UBF is(More)
In this paper, we will propose two identity-based society oriented signature schemes that allow a group of co-signers to collaboratively generate a single signature for a message. The first proposed scheme is designated with known signers and the second scheme is with anonymous signers. Both schemes make use of pairings on elliptic curves in construction(More)
High levels of rRNA synthesis by RNA polymerase I are important for cell growth and proliferation. In vitro studies have indicated that the formation of a stable complex between the HMG box factor [Upstream binding factor (UBF)] and SL1 at the rRNA gene promoter is necessary to direct multiple rounds of Pol I transcription initiation. The recruitment of SL1(More)
