“…For unique and unforgeable ID assignment, we propose to use a solution based on Crypto-Based ID (CBID) [16]: The id i is chosen by the node itself from an ephemeral public/private key pair. More specifically, the node computes id i as follows: id i = H 64 (P K i |N ID), where P K i is M i 's temporary public key or DH public key y i in our schemes, N ID is the network identifier and H 64 (·) a 64-bit long hash function.…”

Abstract. We present two new schemes that, in the absence of a centralized support, allow a pair of nodes of a mobile ad hoc network to compute a shared key without communicating. Such a service is important to secure routing protocols [1][2][3]. The schemes are built using the well-known technique of threshold secret sharing and are secure against a collusion of up to a certain number of nodes. We evaluate and compare the performance of both the schemes in terms of the node admission and pairwise key establishment costs.

“…Apart from digital signatures, CBJX provides an additional lightweight authenticity method by using Crypto-Based Identifiers (CBIDs (Montenegro and Castelluccia, 2004)), which will be discussed in Section 3. At this point, only notice that this method provides authentic messaging without the need of certificates issued by a TTP (Trusted Third Party).…”

JXTA defines a set of six core protocols specifically suited for ad hoc, pervasive, multi-hop, peer-to-peer (P2P) computing. These protocols allow peers to cooperate and form autonomous peer groups. This paper presents a satisfactory method that provides security services to the core protocols: privacy, authenticity, integrity and nonrepudiation. The presented mechanisms are fully distributed and based on a pure peer-to-peer model, not requiring the arbitration of a trusted third party or a previously established trust relationship between peers, which is one of the main challenges under this kind of environments.

“…However, we believe the basis of any security mechanism in P2P overlays are strong and verifiable node identities. We are currently exploring the use of crypto-based IDs [19] for our infrastructure. We are also investigating the use of Threshold Cryptography [18] to implement a distributed admission control mechanism.…”

Abstract. Structured peer-to-peer (P2P) overlay are scalable, robust and selforganizing in nature, and provide a promising platform for a range of largescale distributed applications. Applications proposed to date utilize a similar key-based routing service but "re-invent the wheel" by deploying their own dedicated structured P2P overlay network. This is highly inefficient and results in a significant duplication of work in terms of development, deployment and maintenance of the overlays. To address this problem, we propose a PROgrammable STructured P2P infrastructure (PROST), which allows the dynamic and incremental deployment of multiple applications over a single structured P2P overlay. In this paper, we outline the PROST architecture and discuss the implementation of our prototype.
