PY - 2015 TI - Security in MANET’s by Using Detective Signature Techniques JF - Journal of Computer Science VL - 11 IS - 3 DO - 10.3844/jcssp.2015.526.533 UR - https://thescipub.com/abstract/jcssp.2015.526.533 AB - Mobile Ad-hoc Network (MANET) is one among the fastest growing area in the field of research where security is a vital factor for protecting MANET against attacks, EAACK is an acknowledgement based IDS which is composed of three parts namely, ACK, S-ACK and MRA along with digital signature to provide security against attacks. Till now contemporary technique such as EAACK with watchdog technique are deployed to detect and avoid intruders whereas this technique does not avoid all intruders because it relies on acknowledgement checking and supervisory node. Hence we propose strong and secure cryptographic technique with the help of combining EAACK with dynamic digital signature using TwoFish Cryptographic Algorithm to overcome the mentioned limitations, in order to authenticate and avoid intruders from communication. In this process NS2 is used to simulate and evaluate the proposed scheme.
