Two-Party Key Agreement Protocol for MANETs based on Verifiable Secret Sharing SchemeSeptember 23rd, 2015
Abstract— The nodes of the Mobile Ad Hoc Network (MANET) are movable. This leads to unpredictable nature of node mobility and continuously changing topology there by difficulty in maintaining central control over the nodes of MANET. Secondly, the essential requirement of most of the cryptographic techniques is to share a key between the two end parties of the communication. To address the above two issues and to implement security in MANET environment, there is a basic need of sharing a key between the two communicating parties without the help of central management like Certification Authority CA or Key Generation Centre KCG or Key Distribution Centre KDC. This problem is addressed here with the help of verifiable secret sharing and bilinear pairing concepts. A verifiable secret sharing (VSS) scheme is an extension of standard secret sharing scheme with the additional property that every participant is able to validate whether the share distributed to him by a dealer is accurate.
