Improving the trade-off between storage and communication in broadcast encryption schemes

The most important point in the design of broadcast encryption schemes (BESs) is obtain a good trade-o between the amount of secret information that must be stored by every user and the length of the broadcast message, which are measured, respectively, by the information rate and the broadcast information rate B. In this paper we present a simple method to combine two given BESs in order to imp...

Secret-Public Storage Trade-Off for Broadcast Encryption Key Management

Trade-offs Between Communication and Storage in Unconditionally Secure Schemes for Broadcast Encryption and Interactive Key Distribution

In 1993, Beimel and Chor presented an unconditionally secure interactive protocol which allows a subset of users in a network to establish a common key. This scheme made use of a key predistribution scheme due to Blom. In this paper, we describe some variations and generalizations of the Beimel-Chor scheme, including broadcast encryption schemes as well as interactive key distribution schemes. ...

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...
