Private Information Leakage from Polygenic Risk Scores

Polygenic Risk Scores (PRSs) predict the likelihood of individuals to develop certain diseases based on their genetic variations. However, the privacy implications of publicly sharing PRS values are often underestimated. In this work, we demonstrate …

Reducing metadata leakage from encrypted files and communication with PURBs

Most encrypted data formats leak metadata via their plaintext headers, such as format version, encryption schemes used, number of recipients who can decrypt the data, and even the recipients’ identities. This leakage can …

Axiom - DTLS-based secure IoT group communication

This paper presents Axiom, a DTLS-based approach to efficiently secure multicast group communication among IoT constrained devices. Axiom provides an adaptation of the DTLS record layer, relies on key material commonly shared among the group members, …
