Abstract:
In today’s scenario, there are various ways the attackers can gain access to secure information and use it for
their own benefit. In this paper, we aim to introduce a system to improve the
existing gateway system by
providing more security. This proposed system involves the use of Time-Based One-Time Password (TOTP)
with Quick Response code (QR code). A QR code is a 2D matrix barcode where a large amount of information
can be stored in a compact manner. TOTP is a temporary password that is active for a short duration of time.
For every 30 seconds, a TOTP is generated. A QR code is generated which contains the TOTP. The QR code is
scanned and the server checks the TOTP generated on the server-side. If this TOTP matches with the TOTP in
the QR code then the user is allowed to enter. This method increases the security of the system and prevents
unauthorized access.
Keywords: Authentication, Physical Security, QR Code, Shared Secret Key, TOTP.
1. Introduction
The primary objective of this paper is to introduce a
secure authentication method for gateway entry
system that complements the one currently in use.
The proposed system will use the technological
advancements, like QR code, TOTP and Biometrics
with the aim of increasing the security and reducing
the cost of the system. A comparison of the
proposed system can
be made with the existing
systems used for gateway entry in order to
determine its usefulness.
The existing gateway entry systems mostly use
Radio
Frequency
Identification
(RFID)
[1]
technology for gateway entry authentication. While
RFID is widely used in the industry, it has certain
limitations.
For RFID, special RFID chips and
RFID readers are needed to be deployed in order to
transmit and read the code which increases the cost
of the system. Moreover, RFID tags can also be
cloned [2] and stolen
as there is no way to check
who is using the RFID, leading to security getting
compromised.
In order to overcome these drawbacks of the
existing RFID system,
we are proposing a gateway
entry system that uses Time-Based One-Time
Password (TOTP) with Quick Response code (QR
code). QR code can be generated very easily and
that too at a very low cost and reduces the user
effort as well. The TOTP generated is embedded in
the QR code and lasts only
for a short duration of
time which makes it harder to copy and use. These
features make it harder to penetrate into the system
and provide more security while decreasing the
cost.
