Thus, the contribution of this paper is as follows:Ģ.1.
This behavior can be seen as a fingerprint and as a way to verify the key holder’s identity, thus acting as an authentication layer that is able to prevent the attack or key theft, and at the same time preserving the public’s confidence in these systems. The assumption is that each user exhibits a unique behavior while entering the PIN keys. Secondly, we look at the feasibility of these acoustic emissions be used in enhancing the security level of PEDs. A system that is able to record the sound emissions of keystroke from the PED keypad (for example, ATM Keypads or POS keypads) and extract features which are used to predict the PIN, is shown in Figure 1. First, we investigate the possibility of inferring the PIN key. Therefore, the goal of this paper is to study two aspects of this security issue, i.e., attacks on PEDs and the safeguarding of PEDs against attacks. This makes the information inference extremely challenging and difficult compared to information inference from traditional keyboards in which the user is expected to type for long instances, which increases the inference likelihood of the user data. The PIN entry is quick (small instances of time) because it comprises of a short string of data (4–6 digits) and it is only typed once by the user. ATM keypads allow users to input numeric passwords or PINs. This paper aims to analyze the security vulnerability of modern PEDs, for example ATM keypads or POS terminal keypads. Example are tampering and PIN/card details logging, card wedge allowing transaction approval with no PIN, tampering with Point of Sale (POS) terminals to log PIN and payment data, infecting these devices with malware, and ineffective random number generation by PEDs for cryptographic functions. Several security problems of PEDs not mentioned in the certification already exist. However, whether the standards are strictly implemented is an open question. Theoretically, it should not be possible to perform an attack on the PEDs. One of the most significant requirements for PEDs physical security is that there should not be a feasible way to infer the entered digits on PEDs by recording and analyzing the sound, electromagnetic emissions, power consumption or other external information. The Payment Card Industry (PCI) Standard Council defined the standards of security and testing requirements for certification of devices used for PIN entry in payment and transaction for the first time in 2002. When space or cost is limited, for example, in the case of POS terminals or ATM machines, it is preferable to use numeric passwords, in other words PIN keys.
CHIP PIN KEYPAD LAYOUT PASSWORD
Substantial research has been done on password authentication, including the reasons how users set their passwords, the rules that users use to set passwords and the methods to infer passwords. Passwords are one of the most important personal authenticating methods in the world. This paper focuses on exploring the security vulnerability of such PED terminals. PIN Attack: Acoustic emanations generated from PED keystrokes are recorded and processed to predict a PIN key by an adversary. Usually, PIN key is typed into PIN entry device (PED) or terminal as shown in Figure 1. PIN key is basically small and unique string of data that is ubiquitously used for user authentication and verification. Personal Identification Number (PIN) keys or numeric passwords are widely used in such resource constrained environments.
CHIP PIN KEYPAD LAYOUT VERIFICATION
The process of authentication and verification is important as it allows legitimate personnel to enter and perform various operations in their respective environments. For example, authentication and verification processes are commonly used in Automated Teller Machines (ATMs) and Point of Sale (POS) terminals which are resource constrained systems. Failing to authentication and verification process leads to denial of service. To access different applications and services, user authentication and verification is the first layer of security. IoT devices are resource constrained devices which makes them an attractive target for attacks. Today, IoT provides a wide range of consumer applications.
The Internet of Things (IoT) refers to a network of tiny small wireless sensors that communicate with each other via the Internet.
