On the Security of Huang-Chang Multi-signature Schemes

Recently, based on RSA and discrete logarithm with composite modulus, Huang and Chang proposed two multisignature schemes with distinguished signing authority and claimed that their scheme can resist forgery attack. Unfortunately, in this works, we show that their schemes have forgery attack by security analysis of Huang-Chang multi-signature schemes. Given a multisignature of certain a documen...

Endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) have been shown to communicate with each other via cytokine signaling during neovascularization. In this study, we investigated the effect of platelet-derived growth factor (PDGF), a cytokine released from tumors and ECs, on vascular endothelial growth factor (VEGF) expression in human VSMCs and underlying signal transduction path...

Service composition enables customizable services to be provided to the service consumers. Since the capabilities and the performances of mobile devices (e.g., smart phone, PDA, handheld media player) have improved, a mobile device can be utilized to interact with external mobile service providers towards providing composite Web service to remote clients. Existing approaches on mobile-hosted se...

Fred Chang

Fred grew up in California and studied biology and played the violin at Princeton as an undergraduate. He obtained an M.D. Ph.D. at UCSF, studying under the wise tutelage of the late Ira Herskowitz. As a graduate student, he played with budding yeast ‘shmoos’ and studied how yeast pheromones arrest the cell cycle. He then went to do postdoctoral stints with Paul Nurse in Oxford and London, and ...
