论文摘要
在本文中，提出了基于公钥加密系统的新颖而有效的硬件实现。数字图像被用作通信渠道中发件人和接收方之间的秘密数据载体。拟议的公钥密码系统提供了一个可分开的框架，该框架允许独立地使用公私密钥对嵌入或提取秘密数据，加密或解密载体。 Paillier加密系统被用于加密和解密数字图像的像素。为了达到效率，设计和实施了提议的有效的平行蒙哥马利式核心核心，用于执行Paillier Cryptosystem中的基础现场操作。拟议的地理密码系统的硬件实现结果显示出面积（资源），性能（速度）和功耗方面的效率。我们的地理密码系统代表了一个小的占地面积，使其非常适合嵌入式系统和实时处理引擎，例如医疗扫描设备，自动驾驶汽车和无人机。
In this paper, a novel and efficient hardware implementation of steganographic cryptosystem based on a public-key cryptography is proposed. Digital images are utilized as carriers of secret data between sender and receiver parties in the communication channel. The proposed public-key cryptosystem offers a separable framework that allows to embed or extract secret data and encrypt or decrypt the carrier using the public-private key pair, independently. Paillier cryptographic system is adopted to encrypt and decrypt pixels of the digital image. To achieve efficiency, a proposed efficient parallel montgomery exponentiation core is designed and implemented for performing the underlying field operations in the Paillier cryptosystem. The hardware implementation results of the proposed steganographic cryptosystem show an efficiency in terms of area (resources), performance (speed) and power consumption. Our steganographic cryptosystem represents a small footprint making it well-suited for the embedded systems and real-time processing engines in applications such as medical scanning devices, autopilot cars and drones.
