Architecture Optimization of Group Signature Circuits for Cloud Computing Environment
Sumio Morioka, Jun Furukawa, Yuichi Nakamura, Kazue Sako · 2012
Group signature is one of the main theme in recent digital signature studies. The sig- nature algorithm is a combination of more than 30 elliptic curve (ECC), modular (RSA), long-bit inte- ger (INT) and hash arithmetic operations. Low-power and fast H/W accelerators are strongly desired in cloud computing environment where a lot of client de- vices (mobile devices, embedded systems, sensor de- vices and etc.) are connected to servers in data cen- ter via network. In this paper, we propose a H/W macro-architecture for servers in data center, and will compare it with the architecture for client devices. While these architectures are completely different, we can use the same H/W design methodology where the architectures are explored automatically by a custom- made HLS (High Level Synthesis) tool.
