Kompletný popis

Consider a pay TV provider serving countless users, §who concurrently want to watch a live §transmission of a soccer world championship. How §can the provider restrict access to authorized §users? Conventional access control systems, where §users are supposed to log in and authenticate §themselves, will likely be overloaded. §This book introduces Electronic Subscriptions as a §practicable solution for addressing the mentioned §problem by using cryptographic primitives. It §provides a solid theoretical background and gives §practical solutions for such scenarios. Several §questions are investigated, among others: How to §ensure that only legitimate users are addressed? How §to limit the validity of authorizations (e.g. year, §month etc.)? How to revoke authorized users?
