Security analysis of DTN architecture and Bundle Protocol Specification for space-based networks

A Proactive DOS Filter Mechanism for Delay Tolerant Networks

“…The Bundle Security Protocol (BSP) specification [11] states that bundles have to be validated at a security-aware node for authenticity and integrity. The BSP defines four security blocks for this purpose, for more details see [11] and [12]. To protect the scarce resources of the DTN it is mandatory that bundles are BABprotected and validated.…”

“…This is depicted in Fig. 3 and more details on security blocks can be found in [11] and [12]. To provide DOS-resilience in DTN, we propose a new security extension block called a DTN-COOKIE which adds a weak authentication phase and has less computational overheads at the security-aware nodes.…”

“…Communication time is divided into timeslots of 2 hours interval with each timeslot having its associated nonce value such that (0-2) : S 1 , (2-4) We define the BAB to be a digital signature using asymmetric ciphersuite. Neighbour authentication in inter-regional communications does not make sense since the gateways belong to different regions [12]. Inter-regional communications should be gateway-to-gateway given the limited power budget of wireless mobile nodes.…”

Applying a Security Architecture with Key Management Framework to the Delay/Disruption Tolerant Networks

“…The USB key is used as the storage device hardware which ensures that the private key won't be appear or store temporarily, so it will prevent the illegal users from capturing the private key. Reference [5] proposed a security analysis and bundle protocol specification for DTN space-based networks.…”

Improving Message Dissemination in Opportunistic Networks

“…The last version is the 1.6.0, released in July 2016, and is available in the GitHub repository 1 . This simulator was specifically designed for evaluating the performance of DTN routing and application protocols in wireless networks, see for example [41,74,132,133]. It allows to generate nodes movements using different models, to model messages routing among nodes with various DTN routing algorithms and sender and receiver types and to visualize both mobility and message passing in real time through its graphical user interface.…”
