Research project: Enhanced Zero Knowledge Proof to Preserve Privacy in Blockchain Technology (collaborateion with A*STAR)

Currently Active: 

Although blockchain technology offers a lot of benefits for Internet of Things (IoT) network in terms of security, there are a number of barriers to its widespread adoption. One of these barriers is its pseudo-anonymous feature and it is susceptible to linking attack.  The aim of this project is to analyze the existing zero knowledge proof (ZKP) algorithms in blockchain technology and to redesign ZKP algorithm in order to improve blockchain scalability and cost. ZKP algorithms can be used to verify a transaction without the need to expose their private inputs. However, the work involved in generating a ZKP is computationally intensive. The focus of this project will be on designing an efficient zero knowledge proof algorithm that can be supported by resource constrained IoT devices.
