As a result, securing group communications i.e., providing confidentiality, integrity, and authenticity of messages delivered between group members will become a critical networking issue. In this paper, we present a novel solution to the scalability problem of group multicast key management. We formalize the notion of a secure group as a triple U; K; R where U denotes a set of users, K a set of keys held by the users, and R a user-key relation. We then introduce key graphs to specify secure groups. For a special class of key graphs, we present three strategies for securely distributing rekey messages after a join leave, and specify protocols for joining and leaving a secure group. The re keying strategies and join leave protocols are implemented in a prototype group key server we have built.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783848483679\"\u003e\u003ch3\u003eProviding better security in group communication\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783848483679","offer_id":39487818039389,"sku":"9783848483679","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/8cccc379-3060-425b-b20a-a8ebd18afa8f.jpg?v=1773384064","url":"https:\/\/shop.autorenwelt.de\/products\/secure-group-communication-von-prathap-jonnadula-und-naga-mani-darajula","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
