Abstract

Conference Key Management (CKM) is one of the primary issues inSecure Dynamic Conferencing (SDC). In this paper, we propose anovel CKM scheme for SDC based on the secret sharing principle andthe novel concept/introduction of randomised access polynomial. Ourscheme is simple, efficient, scalable, practical, dynamic andoutperforms existing CKM schemes in overall comparison.Furthermore, if t or less users collude, the new scheme isunconditionally secure and able to defend against their collusions.The storage (O(1) at user end), computation and communicationefficiency of the new scheme makes it well suited for the networkswith low power devices.
