....have been extended to the group setting. Some of these are extensions of the symmetric key distribution techniques used in virtual private networks, as in Enclaves [10] others are extensions of DiffieHellman, such as Group Diffie Hellman (GDH) 21, 22] and its authenticated form A GDH [2]. Some schemes are hierarchical, either physically as in Iolus [18] or abstractly as in various key graph This work was supported by DARPA through SPAWAR Systems Center under Contract N66001 00 C 8014. approaches [23, 12] Different key management approaches can be offered as options over ....

.... in which up to one hundred parties work together in order to get a task done where many of the parties may be sending data to the multicast group [13] Examples of such applications include replicated server [23] audio video conferencing [22] and collaborative tools [2] Several papers [3,20,21,30] have addressed this scenario and one of its incarnations is the system ooeered in [1] However these protocols, and this existing system, are based on or use an informal approach and do not rely on proofs of security. These approaches are several years later often found to be AEawed and, indeed, ....

....model and denitions introduced in [11] and extend them to deal with the authenticated dynamic group DiOEe Hellman key exchange. We dene the partnering, freshness of session key and measures of security for AKE. In this model we dene the execution of a protocol, we refer to it as AKE1, modied from [3] and show that it can be proven secure under reasonable and well dened intractability assumptions. Our paper is organized as follows. In the remainder of this section we summarize the related work. In Section 2 we dene our security model. We use it in Section 3 to dene the security denitions that ....

V. e.g. GDOI [BHHW01] GSAKMP [HCH 01] Some existing key exchange protocols for secure communication have been extended to the group setting (e.g. Group Die Hellman GDH [STW96] and its authenticated form A GDH [AST00] There have been only a few results on the formal analysis of group management protocols (e.g. Pereira and Quisquater analyzed A GDH [PQ01] and Meadows discovered security aws in early versions of GDOI [Mea01] The analysis of group management protocols poses new challenges for formal ....

....is fully distributed, based on key oriented key certificates, and survivable in situations where nodes fail and communication is only occasional. The primary use of our architecture is in access control but it can also be used for authentication in various group key exchange protocols, e.g. [BD94,AST00,AG00]. In addition to the personal networks of electronics, the protocol may find applications in other systems with similar characteristic, including office and home appliances and mobile rescue and military operations. Much of the complexity in our design comes from the fact that on line ....

....of which they have established a session key. For this scenario group Diffie Hellman schemes are attractive alternatives to methods that establish a session key between every pair of players in the multicast group or rely on a centralized key distribution center. Over the years, several papers [2, 3, 13, 18, 20, 21, 27, 31, 32] have attempted to extend the well known Diffie Hellman key exchange [17] to the multi party setting. The protocols meet a variety of performance attributes but only exhibit an informal analysis showing that they achieve the desired security goals. Some papers exhibit an ad hoc analysis for the ....

....honest players. Honest players do not deviate from the protocol and their instances erase any internal data when terminating. Existing twoparty protocols (e.g. SSL and IPsec) make this assumption. We see the additional security goal of dealing with dishonest players (like verifiable contributory [2]) as important in some environments but less important in others [1] This paper provides major contributions to the solution of the group Diffie Hellman key exchange problem. We first present a formal model to help manage the complexity of definitions and proofs for the authenticated group ....

.... In fact, the term intrusion tolerance has been used for the first time in [19] and a sequel of that work lead to a specific system developed in the DELTA4 project [16] In the following years, a number of isolated works, mainly on protocols, took place that can be put under the IT umbrella [10, 31, 22, 2, 24, 4, 21], but only recently did the area develop explosively, with two main projects on both sides of the Atlantic, the OASIS and the MAFTIA projects, doing structured work on concepts, mechanisms and architectures. One main reason is concerned with the fact that distributed systems present fundamental ....

....using the state machine replication approach. Fleet [24] use Byzantine quorum systems [2] to build IT data stores, respectively for data abstractions like variables and locks, and for Java objects. The protocol suite CLIQUES supports group key agreement operations for dynamic groups of processes [4, 3]. More recently, two projects have focused on intrusion tolerance, OASIS and MAFTIA, developing several results that will be detailed ahead. 8.1 OASIS Organically Assured and Survivable Information System (OASIS) is a US DARPA program with the goal of providing defence capabilities against ....
