Algebraic Geometry Codes for Special Broadcast Encryption Schemes in Telecommunication Nets

摘要

Broadcast encryption is a data distribution protocol which can prevent unauthorized parties from accessing the distributed data. It is widely used in distributed storage and network data protection. To prevent the so-called coalition attacks on the protocol, classes of error-correcting codes with special properties are used. In the paper the problem of evaluating the lower and the upper boundaries on coalition power, within which the algebraic geometry codes can be used for broadcast encryption, is considering.
