Improving Security of Producer Consumer System Using Auditing Technique

Abstract

Producer/Consumer system is wide-area infrastructure of
communication which allows distribution of data across
number of producers and consumers. Producer/Consumer
system is messaging system which is arranged in broker-less
routing infrastructure where, messages are published by
producer and these events or messages are received by
consumer based on their subscriptions. Security is one of the
huge and the complicated requirements which has to be
provided so as to attain few issues, like authentication,
integrity and confidentiality and is a challenging task in a
content based producer/consumer system as they are loosely
coupled. To overcome this issue, approach is proposed to
provide an authentication and confidentiality in a broker-less
content-based producer/consumer system by using the
mechanism of pairing-based cryptography. Filtering based
mechanism is used for efficient routing of events or messages.
To detect hacking or any data loss in message transmission
from producer to consumer, the system will generate signature
of event message data which will be helpful to audit that the
data is in proper format or in original format. One time
passwords can be efficiently deployed for Authentication of
the system to provide more security. Producers and consumers
have to face OTP for better Authentication. Evaluation shows
that security providing is affordable with respect to delay for
connection and message sending and cryptographic time.
