We study the problem of maintaining sketches of recent elements of a data stream. Motivated by applications involving network data, we consider streams that are asynchronous, in w...
The amount of data handled by real-time and embedded applications is increasing. Also, applications normally have constraints with respect to freshness and timeliness of the data ...
Security-critical systems are an important application area for formal methods. However, such systems often contain cryptographic subsystems. The natural definitions of these subsy...
A well-known concern in the setting of identity based encryption is that the PKG is all powerful and has to be completely trusted. To mitigate this problem, the notion of Accounta...
The Virtual Black Box (VBB) property for program obfuscators provides a strong guarantee: Anything computable by an efficient adversary given the obfuscated program can also be co...
