New Definitions and Separations for Circular Security

Traditional definitions of encryption security guarantee secrecy for any plaintext that can be computed by an outside adversary. In some settings, such as anonymous credential or disk encryption systems, this is not enough, because these applications encrypt messages that depend on the secret key. A natural question to ask is do standard definitions capture these scenarios? One area of interest...

New Definitions and Designs for Anonymous Signatures

There is a fundamental tension in society between authenticity and privacy, and finding balancesbetween them is an important line of research. In this paper we investigate a tool called anonymoussignatures [12, 21] that is useful in applications like secure auctions. We provide a new formalizationand definition of this primitive that lends the primitive more easily and naturally...

Ten-Kilogram Vehicle Autonomous Operations

A low-cost unmanned ground vehicle designed to benchmark high-speed performance is presented. The E-Maxx four-wheel-drive radio-controlled vehicle equipped with a Robostix controller is proposed as a low-cost, high-speed robotic platform useful for military operations. The vehicle weighs less than ten kilograms making it easily portable by one person. Keeping cost low is a major consideration i...
