Generic Trace and Revoke Scheme ∗
Broadcast encryption (BE) is a cryptographic primitive that allows a broadcaster to encrypt a content to a specific group of users called privileged users and prevent revoked users from decrypting the content even if they collude [6]. In BE schemes, a group of users, called traitors may collude and form a pirate decoder. In order to trace such actions, Traitor tracing (TT) schemes are proposed ...
متن کاملAn Efficient Public Key Trace and Revoke Scheme Secure against Adaptive Chosen Ciphertext Attack
We propose a new public key trace and revoke scheme secure against adaptive chosen ciphertext attack. Our scheme is more efficient than the DF scheme suggested by Y. Dodis and N. Fazio[9]. Our scheme reduces the length of enabling block of the DF scheme by (about) half. Additionally, the computational overhead of the user is lower than that of the DF scheme; instead, the computational overhead ...
متن کاملAttribute-Based Broadcast Encryption Scheme Made Efficient
In this paper, we describe a new broadcast encryption scheme for stateless receivers. The main difference between our scheme and the classical ones derived from the complete subtree paradigm is that the group of privileged users is described by attributes. Actually, some real applications have been described where the use of a more adaptable access structure brings more efficiency and ease of d...
متن کاملEfficient Semi-static Secure Broadcast Encryption Scheme
In this paper, we propose a semi-static secure broadcast encryption scheme with constant-sized private keys and ciphertexts. Our result improves the semi-static secure broadcast encryption scheme introduced by Gentry and Waters. Specifically, we reduce the private key and ciphertext size by half. By applying the generic transformation proposed by Gentry and Waters, our scheme also achieves adap...
متن کاملA Generic View on Trace-and-Revoke Broadcast Encryption Schemes
At Eurocrypt 2011, Wee presented a generalization of threshold public key encryption, threshold signatures, and revocation schemes arising from threshold extractable hash proof systems. In particular, he gave instances of his generic revocation scheme from the DDH assumption (which led to the Naor-Pinkas revocation scheme), and from the factoring assumption (which led to a new revocation scheme...
