Abstract

LED is a lightweight block cipher specifically designed for resource-constrained devices, characterized by low power consumption, minimal memory usage, and high efficiency. These features make it highly suitable for applications in Internet of Things(IoT) devices, Radio Frequency Identification(RFID) tags, and embedded systems. However, as performance demands continue to rise, optimizing the encryption implementation efficiency of the LED block cipher has become a prominent research focus. This study proposes a generalized bit-slicing method for AES-like block ciphers and optimizes its implementation using Single Instruction Multiple Data(SIMD) technology. The method applies to the LED encryption algorithm to enhance its parallel data processing capabilities. Additionally, the study explores S-box optimization schemes for the LED algorithm, reducing the number of logic gates required for S-box implementation. The tests demonstrate that the encryption implementation efficiency of the LED-64 and LED-128 algorithms improved by 2.26 times and 2.14 times, respectively. The experimental results indicate that the proposed method provides significant reference value for the software optimization of AES-like block cipher implementations based on bit-slicing technology.
