Performance Comparison of Digital Signature Based on ECC and RSA
Feng Siquan · Modern Electronics Technique · 2006
The digital signature is the powerful safeguard of the developing of electronic commerce and electronic government.It plays an important role in realizing the functions of identification authentication,data integrity and denying the disavowal.Its realization foundation is encryption algorithm which using publickey encryption algorithm and hash function.At present the main digital signature algorithms are RSA,ELGamal and the Elliptic Curve Cryptography(ECC).This article introduces the general model which is based on ECC and RSA digital signature algorithms.The article also produces the performance comparison of two digital signatures under C~(++).According to the result of comparison,the article analysis the application scope of these two digital signature algorithms.
