Abstract :

The Rapid Expansion Of Internet Of Things (IoT) Devices Within Home Automation Environments Has Created Substantial Security Concerns, Especially For Devices With Limited Resources That Must Operate Within Tight Energy And Processing Constraints. This Paper Introduces NexCrypt, An Innovative Symmetric Encryption Scheme Specifically Tailored For Energy-efficient Smart Home IoT Applications. The Proposed Approach Addresses The Essential Requirement For Secure Yet Lightweight Encryption That Delivers Satisfactory Performance While Reducing Power Usage. Through Extensive Evaluation, We Show That NexCrypt Achieves A 34% Decrease In Gate Equivalence (GE) Relative To Current Lightweight Ciphers, Operates With Just 1.2KB Of Memory, And Reduces Power Consumption By 23% While Sustaining Data Throughput Of 156 Mbps. The Cipher Utilizes A Combined Architecture Integrating Substitution-permutation Networks With Adaptive Key Scheduling To Provide Strong Protection Against Prevalent Cryptographic Threats. Implementation Testing On ARM CortexM0+ Microcontrollers Reveals Notable Enhancements In Power Efficiency And Processing Overhead When Compared To AES128, PRESENT, And Other Leading Lightweight Cryptographic Methods. Our Results Suggest That NexCrypt Offers An Ideal Tradeoff Between Cryptographic Robustness And Resource Conservation, Making It Especially Well-suited For Battery-operated Smart Home Devices Including Wireless Sensors, Smart Locks, And Environmental Monitoring Systems. Keywords: IoT Security, Lightweight Cryptography, Symmetric Encryption, Smart Home Devices, Low-power Computing, Resourceconstrained Systems.
