We have produced a practical software library which supports variable length implementation of the elliptic curve digital signature algorithm ECDSA . We implemented the ECDSA and a recently proposed ECC-based wireless authentication protocol using the library. Our timing results show that the 160-bit ECDSA signature generation and verification operations take around 46 ms and 94 ms respectively. With these timings the execution of the ECC-based wireless authentication protocol takes around 140 ms on the ARM7TDMI processor which is a widely used low-power core processor for wireless applications. 1 Introduction The rapid progress in wireless communication systems personal communication systems and smartcard technologies has brought new opportunities and challenges to be met by engineers and researchers working on the security aspects of the new communication technologies. Public-key cryptography offers robust solutions to many of the existing problems in communication systems however excessive computational demands on-line memory code size and speed have made the use of public key cryptography limited particularly on wireless communication systems. The implementation of public-key cryptography on server and client platforms rarely brings problems due to the availability of high-speed processors and extensive memory space. However in restricted hardware environments with limited computational power and small memory . smartcards and cellular phones we meet more challenges. The integration of the public-key .
