“…Security in-group communications is a highly desirable feature in military and law enforcement DTN scenarios and the need of confidentiality in group communication grows at a day-by-day basis [51]. As presented in Table 4, nearly a handful of works [51][52][53][54] cope with group key management and specifically with rekeying in DTNs. Before delving into the details of the aforementioned works, it is to be noted that group key management protocols should take into account various security requirements such as forward and backward secrecy.…”

Cryptographic Key Management in Delay Tolerant Networks: A Survey

Since their appearance at the dawn of the second millennium, Delay or Disruption Tolerant Networks (DTNs) have gradually evolved, spurring the development of a variety of methods and protocols for making them more secure and resilient. In this context, perhaps, the most challenging problem to deal with is that of cryptographic key management. To the best of our knowledge, the work at hand is the first to survey the relevant literature and classify the various so far proposed key management approaches in such a restricted and harsh environment. Towards this goal, we have grouped the surveyed key management methods into three major categories depending on whether the particular method copes with (a) security initialization, (b) key establishment, and (c) key revocation. We have attempted to provide a concise but fairly complete evaluation of the proposed up-to-date methods in a generalized way with the aim of offering a central reference point for future research.

“…In the multicast area, most of the proposed key management solutions are based on Logical Key Hierarchy schemes [16] [17] [18]. On the other hand, key management in DTN continues to be an active area of research (see references [19] [20] for instance) as both the CCSDS [21] and the DTN Research Group [22] acknowledge that it remains an open issue to be resolved.…”

“…As mentioned in the literature review, this is currently an active area of research in the community and therefore has no unique solution (e.g. [19] [20]). Finally, this paper does not provide any recommendations on which specic security mechanisms should be implemented in order to execute the dierent security functions from gure 3.…”

This paper investigates the provision of information security services in Federated Satellite Systems. We initiate the discussion by describing possible threats that the system faces, as well as the specic security services that have to be provided in order to mitigate them. Next, we dene a set of ve primal security functions that a federated satellite system has to implement and propose the Interaction State Model, a functional model that characterizes the security state when two federates are interacting with each other. Dierences in these security states are then used to dene the Interaction State Machine, a transition state diagram that can be used to rapidly identify which security functionality has to be provided in order to securitize an unreliable interaction.

“…It also ensures end-to-end confidentiality and freshness for end communicating parties. Zhou et al (2014) propose an autonomic group key management scheme for DTNs. Specifically, they present a logical key tree based on one-encryption-key multi decryption-key key protocol for group key management.…”

Key management is considered to be a challenging task in delay tolerant networks (DTNs) operating in environments with adverse communication conditions such as space, due to the practical limitations and constraints prohibiting effective closed-loop communications. In this paper, we propose opportunistic key management as a more suitable solution for key management in networks requiring opportunistic behaviour. We show that opportunistic key management is better exploited and utilised when used in conjunction with routing decisions by security aware DTN nodes.
