Technical Perspective: Cleaning Up Flaws in TLS Implementations
One unfortunate fact about protocols is that as they get older and applied to more scenarios — and TLS is used basically everywhere — they tend to gain weight....

A Messy State of the Union: Taming the Composite State Machines of TLS
We systematically test popular TLS implementations and find unexpected transitions in many of their state machines that have stayed hidden for years. We show how...

Technical Perspective: The Chemistry of Software-Defined Batteries
A time-tested principle in computer systems design is to use an interface to separate an abstraction from its implementation. "Software-Defined Batteries" represents...
