Mobile device integration of a fingerprint biometric remote authentication scheme

Various user authentication schemes with smart cards have been proposed. Generally, researchers implicitly assume that the contents of a smart card cannot be revealed. However, this is not true. An attacker can analyze the leaked information and obtain the secret values in a smart card. To improve on this drawback, we involve a fingerprint biometric and password to enhance the security level of the remote authentication scheme Our scheme uses only hashing functions to implement a robust authentication with a low computation property.

A Memory‐Efficient Fingerprint Verification Algorithm Using a Multi‐Resolution Accumulator Array

Using biometrics to verify a person's identity has several advantages over the present practices of personal identification numbers (PINs) and passwords. At the same time, improvements in VLSI technology have recently led to the introduction of smart cards with 32‐bit RISC processors. To gain maximum security in verification systems using biometrics, verification as well as storage of the biometric pattern must be done in the smart card. However, because of the limited resources (processing power and memory space) of the smart card, integrating biometrics into it is still an open challenge. In this paper, we propose a fingerprint verification algorithm using a multi‐resolution accumulator array that can be executed in restricted environments such as the smart card. We first evaluate both the number of instructions executed and the memory requirement for each step of a typical fingerprint verification algorithm. We then develop a memory‐efficient algorithm for the most memory‐consuming step (alignment) using a multiresolution accumulator array. Our experimental results show that the proposed algorithm can reduce the required memory space by a factor of 40 and can be executed in real time in resource‐constrained environments without significantly degrading accuracy.     

Biometric-based Remote Mutual Authentication Scheme for Mobile Device

Remote user authentication schemes provide a system to verify the legitimacy of remote users’ authentication request over insecure communication channel. In the past years, many authentication schemes using password and smart card have been proposed. However, password might be guessed, leaked or forgotten and smart card might be shared, lost or stolen. In contrast, the biometrics which utilize biological characteristics, such as face, fingerprint or iris, have no such weakness. With the trend of mobile payment, more and more applications of mobile payment use biometrics to replace password and smart card. In this paper, we propose a biometric-based remote authentication scheme substituting biometric and mobile device bounded by user for password and smart card. This scheme is more convenient, suitable and securer than the schemes using smart cards on mobile payment environment.

     

Software and Hardware Issues in Smart Card Technology

An efficient and strongly secure smart card mechanism involves the use of a technological background taken from the fields of computers, VLSI Design and material science. The result of such a mixture is a miniature, fully operational, computation system. The nature of the data involved in smart card transactions and smart card intended uses, introduce another important factor in the smart card design mechanism which is security. The evolution of VLSI technology allows the efficient implementation of costly cryptographic operations in the smart card design methodology. Apart from the traditional cryptographic algorithms, additional techniques and special design materials have been introduced in order to protect the smart card system from cryptanalytic attacks. New architectures of software design, like object-oriented programming, give the opportunity to implement programmable multi-application cards. Thus, smart cards are transformed into highly secure devices and their establishment in the modern computer market can be considered certain. This establishment is bound to finance upcoming research in smart cards so that this product can become the basic component of electronic commerce worldwide.

Wireless broadcast encryption based on smart cards

Wireless broadcasting is an efficient way to broadcast data to a large number of users. Some commercial applications of wireless broadcasting, such as satellite pay-TV, desire that only those users who have paid for the service can retrieve broadcast data. This is often achieved by broadcast encryption, which allows a station securely to broadcast data to a dynamically changing set of privileged users through open air. Most existing broadcast encryption schemes can only revoke a pre-specified number of users before system re-setup or require high computation, communication and storage overheads in receivers. In this paper, we propose a new broadcast encryption scheme based on smart cards. In our scheme, smart cards are used to prevent users from leaking secret keys. Additionally, once an illegally cloned smart card is captured, our scheme also allows tracing of the compromised smart card by which illegal smart cards are cloned, and can then revoke all cloned smart cards. The new features of our scheme include minimal computation needs of only a few modular multiplications in the smart card, and the capability to revoke up to any number of users in one revocation. Furthermore, our scheme is secure against both passive and active attacks and has better performance than other schemes.     

An energy-aware active smart card

Despite recent advances in smart card technology, most modern smart cards continue to rely on card readers for power and clocking, creating a potential security gap. In this paper, we present an energy-aware smart card architecture that operates using an embedded battery and crystal. This low-power VLSI system is continually active and provides enhanced security through periodic internal update when the card is detached from a reader. Our architecture achieves reduced power consumption by deactivating the majority of its circuitry, including an embedded microcontroller, for the vast majority of the card's lifetime. A proof-of-concept prototype implementation of the architecture has been developed including register-transfer-level and gate-level designs which have been synthesized to silicon. To permit extended operation for up to 18 months, critical design logic has been implemented using ultralow-power (adiabatic) circuit techniques.
