—This paper proposes an FPGA-based application-specific elliptic curve processor over a prime field. This research targets applications for which compactness is more important than speed. To obtain a small datapath, the FPGA's dedicated multipliers and carry-chain logic are used and no parallellism is introduced. A small control unit is obtained by(More)
—In the online world, service providers allow users to upload data to be stored or processed. In some cases, privacy will become an essential feature. Sensitive content can be the data provided to or the services used at the service provider. Logging of the actions of the service providers can therefore also generate privacy-sensitive content. However, to(More)
—Bernstein and Lange recently proposed to use Ed-wards coordinates for ECC (Elliptic Curve Cryptography). They claimed them to be more efficient, not only in terms of operation count but also in terms of side-channel security. The latter is thanks to unified point addition and doubling. This work takes on this claim about improved side-channel security of(More)
With the widespread availability of broadband Internet, Field-Programmable Gate Arrays (FPGAs) can get remote updates in the field. This provides hardware and software updates, and enables issue solving and upgrade ability without device modification. In order to prevent an attacker from eavesdropping or manipulating the configuration data, security is a(More)
In earlier published work, Maes et al. present a pay-per-use licensing scheme for hardware Intellectual Property (IP) cores. This scheme focuses on the use of IP cores on static random access memory-based field programmable gate arrays (FPGAs) and is mainly based on the partial reconfigurability property of this type of FPGA. Our work evaluates the(More)
