Multi-service Oriented Broadcast Encryptiona threshold, a rekeying algorithm is proposed to update the user’s service memberships .. We formalize and prove the framework is dynamically secure under the random oracle model. We realize our framework with a scheme based on complete subtree method.

Analysis of a Conference Scheme Under Active and Passive Attackss in the way that a colluding group of attackers can still obtain the conference key even after they all leave the conference. The passive attack does not need any attacker to ever participate in the conference. The conference key can be compromised with a large probability as long as the number of conferees is large.

Multi-service Oriented Broadcast Encryptionhis paper, we suggest a framework called . framework from the subset cover method using RSA exponentiation technique. In this framework, each user’s secret storage is independent of the number of services. Service subscriptions and service providing can be efficiently processed. The service uns

Linear Code Implies Public-Key Traitor Tracing with ,urosawa–Desmedt scheme, can be derived from an [.,.,.]-linear code such that . ≥ 2.+1. In this paper, we show that the linear-coded Kurosawa–Desmedt scheme can be modified to allow revocation of users, that is to show a revocation scheme can be derived from a linear code. The overhead of the modifie

Single Database Private Information Retrieval with Logarithmic Communicationty and a solution with only logarithmic user-side communication complexity. Previously the best result could only achieve polylogarithmic communication on each side, and was based on certain less well-studied assumptions in number theory . On the contrary, our schemes are based on Paillier’s cryp

Information Theoretically Secure Oblivious Polynomial Evaluation: Model, Bounds, and Constructionson the size of the predistributed data, as well as the size of the communications in any (one-round) protocol. We then show that these bounds are tight by exhibiting a scheme for oblivious polynomial evaluation achieveing all the lower bounds simultaneously. We also present a natural generalisation
