Broadcast Encryption Scheme π ?
We propose a new broadcast encryption scheme π based on the idea of ‘one key per each punctured interval’. Let N and r be the numbers of total users and revoked users, respectively. In our scheme with p-punctured c-intervals, the transmission overhead is asymptotically r p+1 as r grows. We also introduce two variants of our scheme to improve the efficiency for small r. Our scheme is very flexib...
متن کاملThe LSD Broadcast Encryption Scheme
Broadcast Encryption schemes enable a center to broadcast encrypted programs so that only designated subsets of users can decrypt each program. The stateless variant of this problem provides each user with a fixed set of keys which is never updated. The best scheme published so far for this problem is the “subset difference” (SD) technique of Naor Naor and Lotspiech, in which each one of the n ...
متن کاملA Tunable Broadcast Encryption Scheme
In this paper, we describe yet another broadcast encryption scheme for stateless receivers. The main difference between our scheme and the classical schemes derived from the complete subtree and its subsequent improvements is that in our scheme the group management is based upon a more adaptable data structure. In these classical schemes, users must be spread on a tree structure where each leve...
متن کامل2-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 کاملCiphertext-Policy Attribute-Based Broadcast Encryption Scheme
In this work, we design a new attribute-based encryption scheme with the revocation capability. In the proposed schemes, the user (broadcaster) encrypts the data according to an access policy over the set of attributes, and a list of the identities of revoked users. Only recipients who have attributes which satisfy the access policy and whose identity is not in the list of revoked users will be...
