摘要：
This paper presents the results of a master thesis were a digital signature generation device (SGD) for RFID tags was developed. The design parameters were a low energy consumption, small chip area, flexibility and the use of Elliptic Curve Cryptography (ECC) over a prime field (GF(p)). Robustness against side channel attacks like simple power analysis (SPA) should be reached. The signature generation device was designed to work as digital coprocessor of an RFID tag without the need for an external calculation unit. Authentication is provided with digital signatures using the Elliptic Curve Digital Signature Algorithm (ECDSA). The ECDSA was implemented using ane coordinates. The goal was to meet the security requirements and to minimize the product of chip area and cycle count, which is related to the energy consumption. The VLSI implementation for a 192-bit word length in 0.35 m standard cells needs a die size of 1.3 mm2 and 500k clock cycles. The signature is generated in 7.5 ms using an energy of 0.556 mWs.
