During these years, the research field of certificateless signature (CLS) scheme is promptly investigated as the key escrow problem in identity-based cryptography can be solved via CLS concept. However, due to the bandwidth limitation of mobile communication and the resource-constraint property of handheld mobile devices, most CLS schemes cannot fulfill the(More)
On behalf of all the ICACT2016 international conference committees, we would like to welcome all of you to ICACT2016. It is a great pleasure for us to host The ICACT is annual international conference in the communications field, where all experts from home and abroad come together to present their work, and share new ideas and visions for achieving the(More)
During these years, the research field of certificateless signature (CLS) scheme without bilinear pairings is promptly investigated as the key escrow problem in identity-based cryptography can be solved via this concept. In this paper, we demonstrate that a certificateless signature scheme proposed by Gong and Li cannot fulfil its security claims. The(More)
