Graph Homomorphisms and Long Range Actions

by Graham R. Brightwell, Peter Winkler , 2001
"... We show that if a graph H is k-colorable, then (k−1)-branching walks on H exhibit long range action, in the sense that the position of a token at time 0 constrains the configuration of its descendents arbitrarily far into the future. This long range action property is one of several investigated her ..."

Delegatable homomorphic encryption with applications to secure outsourcing of computation

by M. Barbosa, P. Farshim - In CT-RSA , 2012
"... Abstract. In this work we propose a new cryptographic primitive called Delegatable Homomorphic Encryption (DHE). This allows a Trusted Authority to control/delegate the capability to evaluate circuits over encrypted data to untrusted workers/evaluators by issuing tokens. This primitive can be both s ..."

Developing Third Party Auditing Scheme for Secure Cloud Storage Service

by Manasi Doshi, Swapnaja Hiray
"... Cloud computing is the use of computing of sources that are delivered as a service over a network. Cloud enables users to store their data, but data is stored at remote location. A major characteristic of the cloud services is that user’s data are usually processed remotely in unknown machines that ..."

Toward Secure and Dependable Storage Services in Cloud Computing

by Cong Wang, Qian Wang, Kui Ren, Ning Cao, Wenjing Lou , 2012
"... Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications without the burden of local hardware and software management. Though the benefits are clear, such a service is also relinquishing users’ physical possession of their outsourced data, whi ..."
