Emerging Privacy-Preserving Technologies in the Data-driven Economy
Prof. Lam Kwok Yan | June 4, 2020
Emerging privacy-preserving technologies are game changing. Privacy has become a hot topic recently in the fight against COVID-19. For example, new contact tracing technologies that are deployed to curb the spread of COVID-19 have increasingly offer large benefits to the society. However, these technologies are constantly tracking and analysing our personal data. High profile privacy scandals have been dominating headlines.
In this talk, Prof. Lam Kwok Yan, director of Strategic Centre for Research in Privacy-Preserving Technologies and Systems (SCRIPTS) at NTU will share his insight to the emerging privacy-preserving technologies that will address these needs. Please refer to this link for the video of the talk.
Concurrent Encryption and Authentication
Prof. Josef Pieprzyk | February 28, 2020
Signcryption aims to provide both confidentiality and authentication of messages more efficiently than the independent application of encryption and signature.
In the talk, we consider a generic and efficient signcryption scheme featuring parallel encryption and signature on top of a sponge-based message-padding underlying structure.
Unlike other existing schemes, the proposed scheme also supports arbitrary long messages.
We prove the construction secure when instantiated from weakly secure asymmetric primitives such as a trapdoor one-way encryption and a universal unforgeable signature.
