Description
Summary:Secret sharing is an important encryption technique in the field of information security. It can ensure the security of secret information. Textured 3D (three-dimensional) mesh model is an information carrier with a large amount of non-integer data. Therefore it takes longer time and computation to share them compared to 2D (two-dimensional) digital images. In this paper, different circuit modules are designed to accelerate the generation of shares and reconstruction of secrets. The hardware architecture enables security while sharing less data. In the data preprocessing phase, the correlation of the edge points of the texture vertices is utilized to filter the texture vertices, which reduces the amount of data to be shared. In the share generation phase, random factors are added. It makes the shares more secure and does not require group reconstruction. Simulation results show that the structure is more than 70 times faster compared to the software implementation. The optimized resource utilization is reduced by more than 60 % . The feasibility of the hardware architecture is verified by conducting experiments on several models and analyzing the results.
