文中利用椭圆曲线密码体制密钥短,安全性高的特点,并结合改进的LSB算法,将加密通信和信息隐藏相结合,提出基于椭圆曲线密码体制与改进的LSB算法的秘密信息隐藏方案。文中对方案的秘密信息嵌入和提取过程都进行了详细阐述。可以根据BMP图像的特点实现是否有秘密信息嵌入的检测,并给出了方案实现的信息隐藏的效果图。

By making use of the characteristics for shorter key and higher security of elliptic curve cryptosystem and improved LSB, a solution for combing the elliptic curve cryptosystem and information hiding is presented. This paper describes a secret information hiding scheme based on elliptic curve cryptosystem and improved LSB. And the processes of embedding and extracting secret information in the scheme are discussed in detail. The detection on whether there exists secret information embedding could he implemented according to the characteristics of BMP images. And the results of information hiding achieved by this scheme are also given.
