An Enhanced Implementation of Elliptic Curve Digital Signature Algorithm

Abstract

In the current modern era, there are a lot of activities that require the presence of human beings, are replaced with a digital data which represent him/her at anytime and anywhere. This digital information is called “Digital Signature”. Digital signatures are very useful for signing important documents, confirming decisions and even banking transactions. The digital world is facilitating our life by making us able to accomplish difficult tasks which is quite a distance from us using such techniques. But there is some trouble we are being faced which is “Security Breach”. This can be done through performing malicious activity against any two parties who are communicating with each other across a certain communication link. The old fashion of attacks against cryptographic scheme is performing a brute force attack until the attacker successfully gets the private key which is associated with a public key. This kind of attack takes more time to break the security, but the problem is that, the attackers have developed new types of attack which are indirect and more efficient called “Side-Channel Attacks”, in which the attacking time is reduced to be some minutes.
