- CADETS Causal, Adaptive, Distributed, and Efficient Tracing System (CADETS), will address flaws in current audit and information-flow systems through fundamental improvements in dynamic instrumentation, scalable distributed tracing, and programming-language support. CADETS has three major components: Event Query (EQ) is a new query language, loosely based on DTrace’s D, that will drive in-application, whole-system, and distributed tracing using temporal expressions and information flow. Watchman is a host-based tracing framework that dynamically introduces variable-granularity instrumentation within and between executing programs. DEQUE distributes EQ expressions over many hosts to track inter-node information flows and temporal sequences, implementing post-hoc trace aggregation, or as needed, tagging of TCP/IP packets, filesystem RPCs, and application-layer protocols with temporal and information-flow labels.
- Pico without public keys Pico is an existing research project seeking to replace passwords with physical tokens. In its existing embodiment, the Pico device authenticates the user to remote services using a public key based security protocol called SIGMA-I.
- Pico Passwords are a pain. Pico is a more usable and more secure replacement that does not require you to memorize any secrets.
- Practical authentication to everyday objects
This project will replace SIGMA-I with a symmetric key based alternative. The advantages of this approach include: minimizing changes required for service providers to adopt Pico, lower energy/computing requirements for wearable platforms and future proofing for attacks against public key cryptography.
