An Optimized Method of Hardware Implementation for LHash in the Embedded System

The security1 of embedded systems has received much attention due to its widespread use and open application environment. Hash function is a commonly used solution to protect embedded system security. Due to the influence of area and power consumption, traditional hash encryption algorithms cannot be directly applied to embedded system because they consume too many resources. Therefore, lightweight encryption algorithms are receiving more and more attention. This paper proposes a method of applying LHash in embedded systems. The experimental results show that the method can correctly implement the LHash algorithm, and can simultaneously consider the area, power consumption and encryption speed, and has good applicability and security.

A multi-level collaboration low-power design based on embedded system

This essay provides a multi-level collaboration low-power design based on embedded processor, builds SoC (System-on-Chip) and designs a low-power SoC by register level, system level and gate level. The designed clock gating module, power management module and system program coordination can be used to realize the sleep and wake up functions on SoC. In order to realize a multi-level collaboration low-power designing, gating clock circuit can be used in circuit designing.

A new ECC scalar multiplication algorithm with randomized power consumption

Scalar multiplication algorithm is the core of the elliptic curve cryptosystem, and it plays a crucial role of the efficiency and security in the process operation of the encryption and decryption. Based on comprehensive analysis of NAF scalar multiplication algorithm and power analysis, this paper proposes a new NAF scalar multiplication algorithm, ensuring the same Hamming-weight with the NAF code and introducing the M-sequence into the random replacement process to achieve power randomization. It not only enhances the ability to work against SPA and DPA attacks, but also improves the storage efficiency, speed and security.
