Comparison Between Two Group Signature Schemes, Hao Yang May 2019

Comparison Between Two Group Signature Schemes, Hao Yang

Rose-Hulman Undergraduate Research Publications

Zerocoin is a cryptographic extension to Bitcoin. During its development, the developers decided to make use of group signature schemes to store and verify the coins. In order to compare the performance of Simple Authentication Scheme and the Dynamic Signature Scheme and figure out which one is the optimal choice for the Zerocoin scheme, I implemented them in Java and analyzed them theoretically. This paper will discuss the performance difference between two schemes, the Java implementation of them and the analysis.

The purpose of this research is to design a new tracking system for solar panels using the idea of discrete-position tracking. Compared with the traditional fixed solar panel, discrete-position trackers have a higher gain of harvesting solar radiation with smaller misalignment angles. Also, since we are trying to design the a passive tracker with solely mechanical structure to do the kinetics, a discrete-position tracker can decrease the cost of the maintenance to a huge extent in contrast to both one-axis and two-axis continuous tracking systems. The majority of the cost of maintaining a continuous tracker is the motor or hydraulic …
