Memristor-Based AES Key Generation for Low Power IoT Hardware Security Modules

Security of Internet of Things (IoT) needs devices and algorithms that offer ultra-low power consumption and a long lifespan, alongside strong immunity against attacks, lower chip area, and acceptable throughput. Hardware security using nanoelectronic technologies shows promise for the area and energy-efficient implementations in IoT. Owing to the recent advances in Memristor as a potential building block for future hardware, it becomes a vital issue to study the role that Memristor will play in hardware security. This work presents a hardware security module for low power IoT security implementations. The proposed module depends on Memristor-based AES key generation relying mainly on the uniqueness of Memristor devices due to fabrication process variations. In addition to taking into consideration the strength properties and great features of Time-based ADC and AES cryptographic algorithm, the proposed hardware security module could meet the needs of modern technology such as secure communication between IoT embedded devices.
