Modified Rabbit Encryption Algorithm With Novel 4-D Chaotic System

Abstract

In recent years, the use of Wireless Sensor Networks (WSN) has become increasingly prevalent across various fields. This has led to a growing need for secure data communication to protect sensitive information. To overcome the limitations of WSNs, lightweight algorithms have gained popularity due to their speed and efficiency.

This paper presents a novel solution for securing sensing data transmitted over WSNs. The proposed modified Rabbit encryption algorithm utilizes a 4-D chaotic system as a key generator to encrypt and decrypt data, providing a robust and efficient solution. The expanded key space generated by the 4-D chaotic system made brute force attacks practically impossible, ensuring data confidentiality and integrity. The use of a strong encryption algorithm and chaotic key generator enhances the system's security and efficiency. The modified Rabbit cipher algorithm encryption execution duration was less than the original Rabbit algorithm, and the chaos increased the randomness and complexity of the cipher. Overall, the proposed encryption algorithm provides a trustworthy solution for securing sensitive data in WSNs.

The results of the NIST and data quality tests suggest that the modified cryptographic Rabbit algorithm is more robust than the original Rabbit algorithm.
