2-Subset Difference Scheme for Broadcast Encryption
Abstract. Broadcast Encryption allows a center to broadcast encrypted messages to a set of users so that only privileged users can decrypt them. In this paper, we propose an efficient broadcast encryption scheme based on the “Subset Difference” (SD) scheme. It reduces the transmission overhead by 50 percent while the storage overhead remains the same but the computational overhead somewhat incr...
متن کاملOptimal subset-difference broadcast encryption with free riders
Broadcast encryption (BE) deals with secure transmission of a message to a group of receivers such that only an authorized subset of receivers can decrypt the message. The transmission cost of a BE system can be reduced considerably if a limited number of free riders can be tolerated in the system. In this paper, we study the problem of how to optimally place a given number of free riders in a ...
متن کاملEnhanced Outsider-anonymous Broadcast Encryption with Subset Difference Revocation
This paper puts forward an efficient broadcast encryption in public key setting employing ternary tree subset difference method for revocation. It provides outsider anonymity disabling the revoked users from getting any information of message and concealing the set of subscribed users from the revoked users. Our approach utilizes composite order bilinear group setting and exhibits significant i...
متن کاملComplete tree subset difference broadcast encryption scheme and its analysis
The Subset Difference (SD) method proposed by Naor-Naor-Lotspeich is the most popular broadcast encryption (BE) scheme. It is suitable for real-time applications like Pay-TV. It has been suggested for use by the AACS standard for digital rights management in Blu-Ray and DVD discs. The SD method assumes the number of users to be a power of two. (1) We propose the Complete Tree Subset Difference ...
متن کاملRational Secret Sharing without Broadcast
We use the concept of rational secret sharing, which was initially introduced by Halpern and Teague [2], where players’ preferences are that they prefer to learn the secret than not, and moreover they prefer that as few others learn the secret as possible. This paper is an attempt to introduce a rational secret sharing scheme which defers from previous RSS schemes in that this scheme does not r...
