Facilitating Security and Trust among Multiple Parties through Blockchain Techniques
A blockchain consists of a list of blocks that are linked based on cryptography hash and maintained by distributed network nodes, so that the information recorded in these blocks is non-repudiated. After its first conceptualization by Nakamoto in 2008, blockchain has attracted broad attention and been considered as a promising solution to establish a decentralized architecture with security. In this talk, we will discuss some key characteristics of blockchain and a few promising applications of blockchain that can facilitate security and trust among multiple parties. Some examples include applying blockchain to secure software updates for resource-constrained IoT networks; designing a secure and efficient multi-signature scheme to facilitate multi-party approval process on Fabric, an enterprise blockchain platform; and facilitating fair trading of digital-goods via a blockchain based proxy re-encryption scheme.
Trust and Privacy Vulnerabilities of Today’s Online Social Networks
As we move further into the big data era, people are motivated in numerous ways to proactively generate, share and exchange diverse digital contents online every day. While the increasing amount of information greatly facilitates people’s decision makings, it also brings great challenges. For example, driven by the huge profits behind the big data economy, malicious attacks are emerging rapidly to mislead normal users’ decision-making process by providing carefully crafted false information. In addition, retrieving tremendous amount of user private information has become a popular attack target. This talk will discuss the security, trust and privacy issues in online social networks, the trend and challenges, particularly focusing on several sample attacks.
