Social Network with Dynamic Identity-based Broadcast Encryption using Security Tree
In this paper, we suggest the security tree scheme using dynamic identity-based broadcast encryption, using this scheme, it is possible to parted a message to many linked nodes and represent these nodes as security tree and give every receiver permission to read special linked nodes from security tree. General Terms Online Social Website is stretched over worldwide such as Facebook, Linked In; ...
متن کاملOn the Security of An Identity Based Broadcast Encryption Scheme
Recently, Ren and Gu proposed a new identity-based broadcast encryption scheme, and claimed that their scheme is secure against chosen-ciphertext attack in the standard model. However, by giving a concrete attack, we indicate that Ren and Gu’s scheme is even not secure against chosen-plaintext attack. Keywordsidentity based broadcast encryption, chosen-ciphertext attack, chosen-plaintext attack...
متن کاملLattice-based Identity-Based Broadcast Encryption
Motivated by the lattice basis delegation technique due to [8], we propose an adaptively secure identity-based broadcast encryption(IBBE) scheme based on the hard worst-case lattice problems. Our construction can be generalized to a hierarchical IBBE (HIBBE) easily. Using the method in [1], we also modify our basic construction to obtain an IBBE in the standard model. To the best of the authors...
متن کاملAugmented Broadcaster Identity-based Broadcast Encryption
Identity-based Broadcast Encryption (IBBE) has the inherent key escrow problem that Private Key Generator (PKG) can fully determine the user’s private key, which is an obstacle of the application of IBBE. The existing approaches to solving key escrow problem need the user to submit identity to multiple PKGs or interactions between PKG and the user in the private key extraction phase. For Point-...
متن کاملGeneralized Identity Based and Broadcast Encryption Schemes
We provide a general framework for constructing identitybased and broadcast encryption systems. In particular, we construct a general encryption system called spatial encryption from which many systems with a variety of properties follow. The ciphertext size in all these systems is independent of the number of users involved and is just three group elements. Private key size grows with the comp...
