Attack on an Improved Algorithm of ECDSA
Hu Hui · Computer and Modernization · 2011
Elliptic Curve Digital Signature Algorithm(ECDSA) is used more and more widely in many applications.By analyzing an improved algorithm of ECDSA,the paper points out its security risk,analyzes its root causes for insecurity,and puts forward an attack method.Such an attack method has the opportunity to obtain a signer's private key with little calculated amount and without the computation of discrete logarithm.
