Elliptic Curve PKI: An Exploration of the Benefits and Challenges of a PKI Based on Elliptic Curve Cryptography

Public-key cryptography has achieved enormous success in protecting users from identity theft resulting from transactions on the Web, e-mail correspondence and VPN sessions. But, it is well accepted in information security circles that cryptographic algorithm strength erodes with time, as the computing power available to cryptanalysts increases and the cryptanalytic...

Fast Elliptic Curve Cryptographic Processor Architecture Based on Three Parallel GF(2k) Bit Level Pipelined Digit Serial Multipliers

Unusual processor architecture for elliptic curve encryption is proposed in this paper. The architecture exploits projective coordinates (x=X/Z, y=Y/Z) to convert GF(2k) division needed in elliptic point operations into several multiplication steps. The processor has three GF(2k) multipliers implemented using bit-level pipelined digit serial computation. It is shown that this...

A Parallel Processing Hardware Architecture for Elliptic Curve Cryptosystems

This paper proposes a parallel processing crypto-processor for Elliptic Curve Cryptography ECC to speed up EC point multiplication. The processor consists of a controller that dynamically checks Instruction-Level Parallelism ILP and multiple sets of modular arithmetic logic units accelerating modular operations. A case study of HW design with the proposed...

Energy Analysis of Public-Key Cryptography for Wireless Sensor Networks

In this paper, the energy cost of authentication and key exchange are quantified based on public-key cryptography on an 8-bit microcontroller platform. The paper presents a comparison of two public-key algorithms, RSA and Elliptic Curve Cryptography ECC, and considers mutual authentication and key exchange between two untrusted parties such as...

Comparing Elliptic Curve Cryptography and RSA on 8-Bit CPUs

Strong public-key cryptography is often considered to be too computationally expensive for small devices if not accelerated by cryptographic hardware. The authors revisited this statement and implemented elliptic curve point multiplication for 160-bit, 192-bit, and 224-bit NIST/SECG curves over GFp and RSA-1024 and RSA-2048 on two 8-bit microcontrollers. To accelerate...

A Public-Key Cryptographic Processor for RSA and ECC

This paper describes an extension to a general-purpose processor for accelerating public-key cryptosystems. Supported are the legacy cryptosystems RSA and DH as well as the newly emerging Elliptic Curve Cryptography ECC system. As this paper will show, minimal extensions suffice to efficiently support these public-key cryptosystems. Due to its computational...
