A Novel Key Distribution Scheme for Link Encryption in MANET
Abstract: Mobile adhoc network is a self organize infrastructure-less wireless network in which every mobile node act as a router to transfer information from one mobile node to another. Adhoc routing protocols are either proactive or reactive. To discover the neighbors, most routing protocols like AODV, DSR use the concept of Hello packet. In this paper, we proposed novel key distribution scheme with Hello packet using steganography for link encryption. Link …

An Automated Smart Contract Repair Framework for Reentrancy, Integer Overflow, and Denial- of-Service Vulnerabilities
Abstract: This paper introduces a novel static analysis framework designed to bridge a long-standing gap in Ethereum smart contract security: the disconnect between vulnerability detection and automated remediation. Although widely adopted tools such as Slither and Oyente are highly effective at identifying security weaknesses, they stop short of providing actionable fixes. As a result, developers manually patch vulnerabilities, a process that is not only time-consuming but also susceptible to human error …
