Resarch of digital seal signature system on ECDSA
Qishan Zhang · Jisuanji gongcheng yu sheji · 2005
Compared ECC (elliptic curve cryptosystems) with RSA (a kind of public key cryptosystems) which is used widely at the present time, ECC has small key and shorter signature length in the same secure intensity, and is great fit to the watermark areas. Combined the technique of ECDSA , watermark and mobile USBkey, the digital seal signature system is researched in detail, and a new method about the combination between digital signature and watermark is put forward, and thesystem will have a significance in practical application.
