چکیده (انگلیسی):

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.
