Paper Title
Cipher SMS Protocol For End-To-End Secure Transmission Of SMS
Abstract
Nowadays, short message service (SMS) is being used in many daily life applications, including
healthcare monitoring, Mobile banking, mobile commerce, and so on. But when we send an SMS from one
mobile phone to another, the information contained in the SMS transmit as plain text Sometimes this
information may be confidential like account numbers, passwords, license numbers, and so on, and it is a major
drawback to send such information through SMS while the traditional SMS service does not provide encryption
to the information before its transmission. In this paper, we propose an efficient and secure protocol called
Cipher SMS, which provides end-to- end secure communication through SMS between end users. The working
of the protocol is presented by considering two different scenarios. The analysis of the proposed protocol shows
that this protocol is able to prevent various attacks, including SMS disclosure, over the air modification, replay
attack, man-in-the- middle attack, and impersonation attack. The Cipher SMS protocol generates minimum
communication and computation overheads as compared with existing Easy SMS, SMSSec and PK-SIM
protocols. On an average, the Cipher SMS protocol reduces 51% and 31% of the bandwidth consumption and
reduces 62% and 45% of message exchanged during the authentication process in comparison to existing
protocols. Authors claim that Cipher SMS is the first protocol completely based on the cryptographic algorithms
and retain original architecture of cellular network.
