Delay Tolerate Networks (DTNs) are highly partitioned networks and suffer from frequent disconnections,which differs significantly from traditional wireless networks.However,long delays and frequent end-to-end disconnections make security in DTNs more challenging.In this paper,we propose a robust security scheme based on elliptic curve cryptography to provide message confidentiality and privacy-preserving for resource-constrained DTNs.The proposed scheme is characterized by a non-interactive manner,thus it is excellent for the delay and end-to-end disconnection features.Moreover,the scheme only requires point multiplication operations on both the sender and the receiver.Therefore,this scheme is suitable for resource-constrained DTNs.
