A PERFORMANCE AND SECURITY COMPARISON OF HYBRID CHAOS-AES WITH OTHER LIGHTWEIGHT IMAGE ENCRYPTION ALGORITHMS IN RESOURCE-CONSTRAINED PLATFORMS

Abstract

The paper uses the comparative analogy of hybrid Chaos-Advanced Encryption Standard (AES) image encryption algorithms, suitable applications in resource-limited set-ups such as the Internet of Things (IoT) and mobile endpoints. Standard AES algorithms are secure, but were made with more powerful systems in mind and therefore are too intensive to work on these low-powered devices. Many alternatives, such as lightweight AES algorithms, are considered too insecure. The research examines hybrid Chaos-AES, which takes characteristics of chaotic systems and mixes them with AES security to produce a hybrid between performance and security. The chaotic systems boost diffusion and encryption, ensuring the improved invulnerability of the algorithms to attacks. The paper compares such methods concerning their cryptographic strength, computational overhead, memory needs, energy consumption, and parameters such as NPCR, UACI, and encryption time. The most important conclusion is that hybrid Chaos-AES schemes provide a stronger level of security against statistical and differential attacks in terms of high NPCR (more than 99.6%) and UACI (almost 33.4) values. Such schemes have 1525 percent improved safety measures compared to lightweight-only algorithms without sacrificing encryption speeds reciprocally adequate to IoT use. The paper finishes by determining that hybrid Chaos-AES is a strong solution to secure and efficient image processing in resource-constrained technological environments.
