嵌入式系统中的椭圆曲线密码技术研究进展

A Review on Elliptic Curve Cryptography for Embedded Systems

Rahat Afreen, S. C. Mehrotra

摘要:

1985年,Neal Koblitz和Victor Miller分别提出了椭圆曲线在密码学中的重要性,此后,椭圆曲线密码学(ECC)逐渐发展成为公钥密码学(PKC)的一个重要研究领域。在PKC系统中,我们使用单独的密钥来编码和解码数据。由于公钥密码体制中的一个密钥是公开分发的,因此其安全性依赖于较大的密钥大小。素因子分解和离散对数的数学问题是以前在PKC系统中使用。ECC已经证明可以用相对较小的密钥大小提供相同级别的安全性。ECC领域的研究主要集中在其在特定应用系统上的实现。这样的系统具有有限的资源,如存储、处理速度和特定于域的CPU架构。

英文摘要:

Importance of Elliptic Curves in Cryptography was independently proposed by Neal Koblitz and Victor Miller in 1985.Since then, Elliptic curve cryptography or ECC has evolved as a vast field for public key cryptography (PKC) systems. In PKC system, we use separate keys to encode and decode the data. Since one of the keys is distributed publicly in PKC systems, the strength of security depends on large key size. The mathematical problems of prime factorization and discrete logarithm are previously used in PKC systems. ECC has proved to provide same level of security with relatively small key sizes. The research in the field of ECC is mostly focused on its implementation on application specific systems. Such systems have restricted resources like storage, processing speed and domain specific CPU architecture.
