Abstract

In an increasingly connected world, security is a top concern for Internet of Things (IoT). These IoT devices have to be inexpensive implying that they will be constrained in storage and computing resources. In order to secure such devices, highly efficient public key cryptosystems (PKC) are critical. Elliptic Curve Cryptography (ECC) is the most commonly implemented PKC in use today. In this paper, an alternate and a more efficient PKC, called the PEC (Pells Equation Cryptography) has been proposed based on Pells equation: x−D ∗y ≡ 1 (mod p). It is shown that scalar multiplication in PEC is significantly more efficient compared to ECC. It is also shown that the Discrete Logarithm Problem computing the private key from the public key in PEC is at least as hard as that of ECC.

PEC——一个替代的和更有效的公钥密码系统

在一个日益互联的世界中，安全是物联网(IoT)的首要关注点。这些物联网设备必须价格低廉，这意味着它们将受到存储和计算资源的限制。为了确保这些设备的安全，高效的公钥密码系统(PKC)至关重要。椭圆曲线加密(ECC)是目前使用的最常见的PKC实现。在本文中，基于Pells方程:x−D∗y≡1 (mod p)，提出了一种替代且更有效的PKC，称为PEC (Pells Equation Cryptography)。结果表明，PEC中的标量乘法比ECC更有效。研究还表明，PEC中从公钥计算私钥的离散对数问题至少与ECC一样困难。

期刊介绍： The paradigm for the next generation of information systems (ISs) will involve large numbers of ISs distributed over large, complex computer/communication networks. Such ISs will manage or have access to large amounts of information and computing services and will interoperate as required. These support individual or collaborative human work. Communication among component systems will be done using protocols that range from conventional ones to those based on distributed AI. We call such next generation ISs Cooperative Information Systems (CIS). The International Journal of Cooperative Information Systems (IJCIS) addresses the intricacies of cooperative work in the framework of distributed interoperable information systems. It provides a forum for the presentation and dissemination of research covering all aspects of CIS design, requirements, functionality, implementation, deployment, and evolution.
