Secure Key Establishment for Bundle Security Protocol of Space DTNs in Noninteractive Manner
DTN's i.e. Delay Tolerant Networks are emerging networks that are widely used in the communication field for implementing a more efficient protocol to use the available bandwidth in the network. DTNs are time independent message delivery systems. It is a kind of store and forward. However the security aspects of these networks are of more concerning subject. So to ensure and increase the authenticity, integrity, and confidentiality, the committee for space data systems Bundle Security Protocol (BSP) specification has suggested four IPsec style security headers to provide four aspects of security services of bundles.
