Elliptic curve cryptography is a public key cryptosystem based on the elliptic curve discrete logarithm problem. The reason for the attractiveness of ECC is that there is no sub-exponential algorithm known to solve the elliptic curve discrete logarithm problem. This leads to lower memory requirements, lower computation requirements and higher security than other public key cryptosystems. This project...
The transport layer security (TLS) protocol is currently the predominant method of implementing Internet security. This paper proposes an FPGA-based embedded system integrating hardware that accelerates the cryptographic algorithms used in the SSL/TLS protocol. OpenSSL, an open source implementation of the SLL v3 and TLS v1 protocol, is deployed in the proposed embedded system powered with a Nios-2...
Identity-based cryptography has been gradually accepted as a more effective way of implementing asymmetric cryptography. The calculation of cryptographically-suitable pairings is crucial for the performance of pairing based protocols. In this paper we present a comparative study of hardware implementation techniques for computing the ??T pairing over the finite field F3{su97|}. Our hardware-software...
In this paper, a generic elliptic curve (EC) arithmetic unit with high flexibility and small chip covered area is proposed. This EC arithmetic unit is based on the one dimensional systolic architectural realization of a proposed modified multiplication - inversion algorithm that through appropriate initialization uses the algorithmic structure of inversion to also perform multiplication. The proposed...
This paper presents SPA (simple power analysis) attacks against public-key cryptosystems implemented on an FPGA platform. The SPA attack investigates a power waveform generated by a cryptographic module, and reveals a secret key in the module. We focus on chosen-message SPA attacks, which enhances the differences of operating waveforms between multiplication and squaring correlated to the secret key...
