Problems solved by technology

However, this protocol has many flaws when used in the above scheme
For example, the protocol needs to involve a trusted third party tasked with providing some target layer of trust between two parties; likewise, messages generated under the protocol always require some form of digital signatures and / or zero-knowledge proofs, which are computationally expensive; moreover, the protocol requires the use of asymmetric (public) keys provided to the endpoints

Abstract

An authentication system is disclosed. The authentication system includes a content provider configured to distribute encrypted content, wherein the encrypted content is generated using a content key, and a client having a symmetric key and configured to store the encrypted content received from the content provider and issue a request to the content provider, wherein the request includes a cryptographic function configured to have the symmetric key and the encrypted content as input, wherein the content provider is further configured to verify the client via the request to ensure that the client has received the encrypted content.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 60 / 607,024, filed September 2, 2004, which is hereby incorporated by reference in its entirety. field of invention [0003] The present invention relates generally to broadcast material and, in particular, to methods and systems for managing authentication and payment for use of broadcast material. technical background [0004] In a wireless broadcast environment, it is advantageous to use spare broadcast capacity to distribute unsolicited material or content to terminals for storage, even though users may or may not care about the content at the time of distribution. A terminal may be mobile, including, for example, a mobile phone. Content may include a variety of information including, for example, textual information, audiovisual material, games, and the like. Typically, the broadcast service provider who distributes the content can restrict its...
