Consider a system where a data files (F_i, and i denotes the file ID) is distributed over a cloud. A data file is generated by an author (AU_k, and k, denotes the author ID) and stored on a distribution server (DS). Only authorized users (US_1, and denotes the user ID) previously registered on the system using their private keys (KPR_1) are allowed to download the data. Users' public certificates (KPU_1) and revocation lists (CRL) are available on a trusted Certificate...
Linear Algebra Graph and Matricies Introduction One of the most interesting applications of linear algebra is to the problem on network analysis. The system of highways or city roads constitutes a network, as does a telephone communication network, or even the World Wide Web. In order to analyze highly complex networks, it is necessary to use fast computers and advanced methods, but the journey must begin somewhere and I hope that for you it starts here today, by analyzing some...
