This paper presents Elliptic Curve Digital Signature Algorithm (ECDSA) hardware implementation over Koblitz subfield curves with 163-bit key length. We designed ECDSA with the purpose to improve performance and security respectively by using elliptic curve point multiplication on Koblitz curves to compute the public key and a key stream generator “W7” to generate private key. Different blocs of ECDSA are implemented on a reconfigurable hardware platform (Xilinx xc6vlx760-2ff1760). We used the hardware description language VHDL (VHSIC Hardware Description Language) for compartmental validation. The design requires 0.2 ms, 0.8 ms and 0.4 ms with 7 %, 13 % and 5 % of the device resources on Slice LUT for respectively key generation, signature generation and signature verification. The proposed ECDSA implementation is suitable to the applications that need: low-bandwidth communication, low-storage and low-computation environments. In particular our implementation is suitable to smart cards and wireless devices.
