We propose an efficient Key-policy Attribute-based Encryption (KP-ABE) scheme for general (monotone) Boolean circuits based on secret sharing and on a very particular and simple form of leveled multilinear maps, called chained multilinear maps. The number of decryption key components is substantially reduced in comparison with the scheme in [6], and the size of the multilinear map (in terms of ...

Abstract. External barrier options are two-asset options with stochastic variables where the payoff depends on one underlying asset and the barrier depends on another state variable. The barrier state variable determines whether the option is knocked in or out when the value of the variable is above or below some prescribed barrier level. This paper derives the explicit analytic solution of the...

In this Letter, a strategy for more secure communication using chaotic signals is presented. In this approach, the transmitter is composed by a chain of chaotic oscillator where the input to the first oscillator is modulated by the information signal and the transmitted signal is the output of the last oscillator. The receiver is a linear asymptotic approximation to the inverse of the transmitt...

Networks of classifiers are capturing the attention of system and algorithmic researchers because they offer improved accuracy over single model classifiers, can be distributed over a network of servers for improved scalability, and can be adapted to available system resources. However, resource management for a network of classifiers, each with a range of operating points, is challenging becau...
