.... the set of master keys, the corresponding pseudorandom number generator and the seed are easily exposed and hence the active key of any cell can be found out. The requirement of nodes being able to discover their coordinates is also too demanding for our case. Luo et al. s localized trust model [9] is not exactly a key management architecture proposal, but it can be regarded as such. This model is based on (k, n) threshold secret sharing, wherein a system secret key (of a public private key pair) is shared among every n nodes, and a node is only trusted if it acquires a certificate issued ....

....through a wireless overlay network [25] e.g. using GPRS in a wide area environment, while switching to 802.11 or Bluetooth in an indoor environment. To identify each node, we assume that each node has a certificate issued by a scalable certificate authority such as those proposed in [26] [27]. For concreteness of presentation, we assume that the sender knows the full path from the sender to the destination, using a secure ad hoc routing protocol based on DSR [28] 29] 30] The incentive issues of route discovery will be investigated in Section VI. When a node sends its own ....

....and trust management) is based on the notion of trust and it is not well defined for ad hoc networks. Centralized security solutions for ad hoc networks could be significantly vulnerable [2] Recently, a lot of effort has been put in providing security infrastructure for ad hoc networks [2, 3, 4, 5]. These efforts aim at distributing CA functionality to a set of nodes in the network. In this paper, we propose, troups, a cryptographically secure, fault tolerant, scalable trust model for resilient peer to peer networks. Our design employs a secure group based approach for the creation of a ....
....is illustrated in Section 3. Section 4 provides the security protocols for this trust model. It also illustrates that the constructs are cryptographically secure. The implementation of the verification protocol and performance results are provided in Section 5. 2 Background Recent publications [2, 4, 5] propose the idea of making existing authentication models in the Internet (Hierarchical and PGP) 1] suitable for mobile ad hoc networks. 2.1 Threshold Cryptography In [2, 4] the use of threshold cryptography is proposed to distribute CA functionality to various nodes. In [4] private key of ....

....# such that g input (key) # # (g # input (share 1 ) g # input (share t 1 ) 1) The RSA signature function is homomorphic, and thus satisfies this property. The bottomline of this insight is that a distributed public key infrastructure that is similar to Luo et al. s local trust model [5] can now be established. In this model, every node has a public private key pair and is only trusted if it owns a certificate (carrying its identity and public key) signed by t 1 trusted neighbours. For pairwise keying, Di#e Hellman derived or RSA protocols can be used, whereas one of the many ....
