基于椭圆曲线数字签名的软件加壳保护技术的实现

The Implementation of Software Shelling Protection Scheme Based on ECDSA

结合软件加壳、脱壳技术,提出了一种基于椭圆曲线数字签名算法的软件保护方案,并用JBuilder语言实现其基本功能。该方案的安全性不寓于算法本身,只要密钥不被泄漏,破解者无法根据算法和公钥生成新的私钥,因此具有很好的安全性和有效性。

According to the software shelling technology, the authors put forward a software protection scheme based on Digital Signature Algorithm of ECC by means of JBuilder language. Because the security of this scheme is determined by private key instead of the algorithm itself, users can＇t construct new cryptography by given algorithm and the public key as long as the private key is kept safe. The analysis shows that the scheme is very secure and effective.
