Secure blockchain technologies
In the recent years, blockchain technologies have shown promise as infrastructure for decentralized trustless anonymous digital asset exchange. The technology promises to transform how the data is shared in many areas including financial sector, insurance and gaming industries. Yet several obstacles prevent mainstream adoption of this technology - one of these challenges is security. To facilitate trustworthy data collection, and management in blockchain, ensuring secure communication is essential.
The blockchain’s underlying cryptographic theory makes it difficult for an adversary to modify the data provenance. Yet, the technology is not immune to unauthorized access, modifications, and repudiation of origin. This research aims to address these security problems and develop methodologies to predict, track and analyze suspicious users, their behaviour, and corresponding threats in blockchain.
