The task of this paper is to introduce a new lightweight identification protocol based on biometric data and elliptic curves. In fact, we combine biometric data and asymetric cryptography, namely elliptic curves and standard tools to design a multifactor identification protocol. Our scheme is light, very fast, secure and robust against all the known attacks on identification protocol. Therefore...

Internet Of Things is an evolution and superset of current internet of networks of computers. We are already on the way of connecting every Thing to internet, mobile internet focusing on 3G phones is a good pioneer example. Our focuses are turning from devices with high capability of computing and storage to those with constrained resources (CPU, memory, energy), from reliable transportations t...

In diesem Artikel wird ein Überblick über leichtgewichtige Kryptographie (lightweight Cryptography) gegeben. Weiterhin werden die beiden neuen auf Hardware optimierten Chiffren DESL und PRESENT näher vorgestellt. Der anschließende Vergleich der Implementierungsergebnisse mit anderen kürzlich vorgeschlagenen Blockchiffren wie mCrypton, HIGHT oder CLEFIA zeigt, dass DESL und PRESENT weniger Chipf...

Data security is in Demand in everyday life of Digital World, since Digital data’s can be reproduced much easily. To achieve the maximum security required a Parallel Processing, User Reconfigurable Cryptographic RISC Microprocessor is proposed in our paper. Rather than protecting the data using tools and external codes, a microprocessor is specially designed in our project to offer maximum digi...

The evolution of embedded systems and their applications in every daily activity, derive the development of lightweight cryptography. Widely used crypto-libraries are too large to fit on constrained devices, like sensor nodes. Also, such libraries provide redundant functionality as each lightweight and ultra-lightweight application utilizes a limited and specific set of crypto-primitives and pr...

In this paper, we propose an algebraic attack on stream ciphers. Starting from a well-known due to Courtois and Meier, design especially effective against nonlinear filter generators. First, test it two toy ciphers then show that the level of security WG-PRNG, one submitted NIST competition Lightweight Cryptography, is less than claimed until now.

Remote Patient Monitoring (RPM) provides flexible and powerful patient surveillance through wearable devices at anytime and anywhere. This can be achieved by using a Body Sensor Network (BSN), which is deployed on a human body for monitoring the healthcare. The mobile healthcare management with increased feasibility and handiness introduced several noteworthy challenges for the provider, policy...

The domain of lightweight cryptography focuses on cryptographic algorithms for extremely constrained devices. It is very costly to avoid nonce reuse in such environments, because this requires either a hardware source of randomness, or non-volatile memory to store a counter. At the same time, a lot of cryptographic schemes actually require the nonce assumption for their security. In this paper,...
