Abstract

Elliptic Curve Cryptography (ECC) is a promising cryptosystem as it presents the ideal choice for implementing public-key cryptography in resource-limited devices, such as those found in envisioned Internet of Things applications, e.g. wireless sensors. Elliptic Curve ElGamal (ECEG) is a renowned member of the ECC family. However, it requires encoding the message before encryption and decoding it after decryption. To better improve the processing time and to avoid sharing a lookup table, we propose, in this document, a new method that exchanges encoding parameters and authenticates endpoints at the same time. So, our new protocol ensures the authentication of communication parties and integrity of ephemeral encoding parameters. The robustness of our solution is proven by the Scyther tool. Experimental tests have been carried out, and the performance of the new methods is provided and compared with RSA and related work. Security and performance analysis show that our new scheme has achieved improved functionality and higher security while maintaining low computational.
基于椭圆曲线El - Gamal的轻量级认证方案
椭圆曲线加密(ECC)是一种很有前途的加密系统,因为它为在资源有限的设备中实现公钥加密提供了理想的选择,例如在设想的物联网应用中发现的设备,例如无线传感器。椭圆曲线ElGamal (ECEG)是ECC家族中著名的成员。但是,它要求在加密之前对消息进行编码,在解密之后对消息进行解码。为了更好地改进处理时间并避免共享查找表,本文提出了一种同时交换编码参数和验证端点的新方法。因此,我们的协议保证了通信双方的身份验证和临时编码参数的完整性。Scyther工具证明了我们的解决方案的健壮性。进行了实验测试,给出了新方法的性能,并与RSA及相关工作进行了比较。安全性和性能分析表明,新方案在保持较低的计算量的同时,实现了更强的功能和更高的安全性。
