One-time password
A one-time password (OTP) is a password that is valid for only one login session or transaction, on a computer system or other digital device. OTPs avoid a number of shortcomings that are associated with traditional (static) password-based authentication; a number of implementations also incorporate two factor authentication by ensuring that the one-time password requires access to something a person has (such as a small keyring fob device with the OTP calculator built into it, or a smartcard or specific cellphone) as well as something a person knows (such as a PIN).
The most important advantage that is addressed by OTPs is that, in contrast to static passwords, they are not vulnerable to replay attacks. This means that a potential intruder who manages to record an OTP that was already used to log in to a service or to conduct a transaction will not be able to abuse it, since it will no longer be valid. A second major advantage is that a user who uses the same (or similar) password for multiple systems, is not made vulnerable on all of them, if the password for one of these is gained by an attacker. A number of OTP systems also aim to ensure that a session cannot easily be intercepted or impersonated without knowledge of unpredictable data created during the previous session, thus reducing the attack surface further.
Abstract
The main purpose of this paper is to design and
implement advance locker security system. In today’s
materialistic world, security holds an in dispensable place.
There is a need of security in almost every sector of society viz.
offices, houses, banks etc. as thefts and robberies are
increasing day by day. To overcome this security threat, a
security system has been proposed using Controller and GSM
technology. This system is basically a controller based accesscontrol
system which allows only authorized person to access
the locker with GSM technology. This system activates,
authenticates and validates the user and then unlocks the door.
It is standalone system controller is used to generate random
password whereas GSM technology is used to send the
password to the authorized person’s mobile phone via SMS.
INTRODUCTION
In most of the offices and banks lockers are used to
secure valuable documents or any valuable thing so Locker
security is becoming an important issue in recent days.
Nowadays there is demand for more efficient security
systems to avoid access of unauthorized persons. In resent
system a unique password is set to open locker, which is
only known to authorised person. The user uses this
password again and again so somebody can hack that
password and also if password leaks then it affect security
of system. The most of locker systems are based on only
mechanical key operations; if key is misplaced or stolen
then again it is difficult to maintain security of that locker.
There are some security systems based on GSM,
Fingerprint and RFID exists. In [2] RFID technology is
used to read the customer information whereas GSM
technology is used to send the password to the authorized
person’s mobile phone via SMS.
GSM Modem
A GSM modem is a wireless modem that works with a
GSM wireless network as shown in Fig 2. A wireless
modem behaves like a dial-up modem. The main difference
between them is that a dial-up modem sends and receives
data through a fixed telephone line while a wireless modem
sends and receives data through radio waves. Like a GSM
mobile phone, a GSM modem requires a SIM card from a
wireless carrier in order to operate.
A GSM modem can be an external unit or a PCMCIA
card (also called PC Card). An external GSM modem is
connected to a PC through a serial cable, a USB cable,
Bluetooth or Infrared. Like a GSM mobile phone, a GSM
modem requires a SIM card from a wireless carrier in order
to operate
