Offshored Service Cost Model as a Key Post-Transition Challenge

Key Management as a Service

In this paper we consider the security issues related to the key management in cloud computing. We focus on the difficulty of managing cryptographic keys necessary to maintain for example the confidentiality of information stored in the clouds. In this framework, we present a threshold cryptosystem as well as three protocols, based on cooperation between cloud providers and a random number gene...

A Low Cost Private Key Reissuing Model

Post-Challenge Leakage Resilient Public-Key Cryptosystem in Split State Model

Leakage resilient cryptography is often considered in the presence of a very strong leakage oracle: An adversary may submit arbitrary efficiently computable function f to the leakage oracle to receive f (x), where x denotes the entire secret that a party possesses. This model is somewhat too strong in the setting of public-key encryption (PKE). It is known that no secret-key leakage resilient P...

Model Identification: A Key Challenge is Computational Systems Biology

The primary goal of computational systems biology is the integration of biological data into mathematical models. Due to rapid advances in biological techniques, these data consist more and more of cellular responses in the form of time series measurements of gene expression, protein abundances, or metabolite concentrations following some stimulus. Time series data contain enormous information,...

Unbundled Reactive Support Service: Key Characteristics and Dominant Cost Component

In this paper, we present a systematic exposition of generator-provided reactive support as an unbundled ancillary service under open access transmission. We discuss the nature and salient physical characteristics of reactive support and analyze their implications in acquiring VAr support as one of the ancillary services. The paper provides an analysis of the dominant component in the cost stru...
