KEY AGREEMENT PROTOCOL FOR DISTRIBUTED SECURE MULTICAST FOR eASSESSMENTKey Agreement • February 13th, 2018
Abstract: eAssessment is typical for online and distance learning, but nowadays it is also applicable in institutions with blended-learning delivery mode, because of advantages that proposes to teachers and learners: performance of online examination in time suitable for learners and from any geolocation, immediate feedback and exam results. In several learning scenarios, the eAssessment could occur in groups where the multicast communication from type one-to-many or man-to-many could be performed. In this case, the arising problem concerns security in collaborative and synchronous environment. It is important to protect all participants from false messaging and illegal behavior. One solution of this problem is implementation of multicast security which main benefits are related to: high scalable, fast re-key operation, decreased network load. The aim of the paper is to present a key exchange protocol for distributed multicast security. The advantage of the protocol is that it offers m
