摘要

This paper presents a performance study and analysis of two popular public-key cryptosystems: RSA with its two variants, and ECC (Elliptic Curve Cryptography). RSA is considered as the first generation public-key cryptography, which is very popular since its inception while ECC is gaining its popularity recently. Besides studying and analyzing the paper also suggests the supremacy among these cryptosystems based on the experimentation. The paper shows the result of the experimentation performed using these cryptosystems with the different modulus/key sizes recommended by the NIST. The modulus/key sizes are used such as 1024/2048/3072-bit for RSA and 160/224/256-bit for ECC. After experimentation and execution of these cryptosystems, the paper concludes that an ECC-based cryptosystem is better than an RSA or its variants-based cryptosystem, and an ECC based cryptosystem best suits for memory-constrained devices, as an ECC-based cryptosystem requires fewer resources than an RSA-based cryptosystem.
