Design and formal verification of DZMBE+
In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...
متن کاملKey Preassigned Traceability Schemes for Broadcast Encryption
Traceability schemes for broadcast encryption are deened by Chor, Fiat and Naor in 6] to protect against a possible coalition of users producing an illegal decryption key. Their scheme was then generalized by Stinson and Wei in 17]. These schemes assume that every user can decrypt the secret value. In this paper we discuss key preassigned tra-cability schemes, in which only the users in a speci...
متن کاملAn Overview of Group Key Management Issues in IEEE 802.16e Networks
The computer industry has defined the IEEE 802.16 family of standards that will enable mobile devices to access a broadband network as an alternative to digital subscriber line technology. As the mobile devices join and leave a network, security measures must be taken to ensure the safety of the network against unauthorized usage by encryption and group key management. IEEE 802.16e uses Multica...
متن کاملArtemia: a family of provably secure authenticated encryption schemes
Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...
متن کاملFuzzy retrieval of encrypted data by multi-purpose data-structures
The growing amount of information that has arisen from emerging technologies has caused organizations to face challenges in maintaining and managing their information. Expanding hardware, human resources, outsourcing data management, and maintenance an external organization in the form of cloud storage services, are two common approaches to overcome these challenges; The first approach costs of...
