In this paper, we propose a new cryptosystem based on matrix translation and Elliptic curve cryptography for developing a secure routing algorithm to provide energy efficient and secured data communications in Wireless Sensor Networks. Moreover, the newly proposed techniques are implemented by decomposing the process into the key generation phase, encryption phase, cluster based secure routing phase and decryption phase. For this purpose, we introduce two new tables namely space reference table and String Position based ASCII value and Prime number generation Table. Here, the Space reference table is used to assign the values for the spaces that are occurring in the sentence before the encryption and decryption process. Next, it uses the String Position based ASCII value and Prime number generation Table developed in this work to convert the strings into numerical digits and to allocate the nearest prime number for the generated numerical digits. In addition, we propose two new algorithms namely ASCII AND PRIME NUMBER based Encryption/Decryption Algorithm and a Secure Routing Algorithm using cipher text conversion and distance vectors called Matrix Translation and Elliptic Curve based Cryptosystem for Secure Routing Algorithm for performing cluster based and energy efficient secure routing. The major advantages of the proposed secure routing system include the increase in security, packet delivery ratio and overall network performance and also decrease in energy consumption and delay. This work has been implemented using NS2 simulator and Java.

在本文中，我们提出了一种基于矩阵转换和椭圆曲线密码学的新型密码系统，用于开发一种安全的路由算法，以在无线传感器网络中提供节能高效的数据通信。此外，通过将过程分解为密钥生成阶段，加密阶段，基于集群的安全路由阶段和解密阶段来实现新提出的技术。为此，我们引入了两个新表，即空间参考表和基于字符串位置的ASCII值和素数生成表。在此，空格参考表用于为加密和解密过程之前的句子中出现的空格分配值。下一个，它使用在此工作中开发的基于字符串位置的ASCII值和质数生成表将字符串转换为数字，并为生成的数字分配最接近的质数。此外，我们提出了两种新算法，即基于ASCII和PRIME NUMBER的加密/解密算法，以及一种使用密文转换和距离矢量的安全路由算法，称为矩阵平移和基于椭圆曲线的密码系统，用于安全路由算法，以执行基于集群和节能高效的安全路由。所提出的安全路由系统的主要优点包括安全性，分组传送率和整体网络性能的提高，以及能耗和延迟的减少。这项工作已经使用NS2模拟器和Java来实现。
