Credit card or portable identification cards containing smart card technology and electronic fuse (e-fuse) technology are combined with an LFSR pseudo random number generator to provide a secured method to prevent fraud and unauthorized use. Secure personalization via e-fuses, a pseudo-random number generator linear feedback shift register, free running clock oscillator, and power source embedded in the card provide a highly secured method to render a lost or stolen card useless. A unique card ID is permanently encoded within the card which requires a specific activation code to activate the card. A PIN number permits the card owner to activate the card for a predetermined length of time while processing a transaction. The card dynamically generates random code sequences and synchronization keys to secure a transaction.

Secure credit card

In a protocol for preserving the privacy of communications between a RFID reader and a RFID tag, two distinct actions are taken. First, the reader and the tag must be mutually authenticated as being authorized participants in the communications. After that process is successfully completed, the authenticity of each authorized participant must be validated prior to each subsequent communication between reader and tag.

In the last few years the Internet of Things (IoT) has seen widespreadapplication and can be found in each field. Authentication and accesscontrol are important and critical functionalities in the context of IoTto enable secure communication between devices. Mobility, dynamicnetwork topology and weak physical security of low power devices in IoTnetworks are possible sources for security vulnerabilities. It ispromising to make an authentication and access control attack resistant andlightweight in a resource constrained and distributed IoT environment.This paper presents the Identity Authentication and Capability basedAccess Control (IACAC) model with protocol evaluation and performanceanalysis. To protect IoT from man-in-the-middle, replay and denial ofservice (Dos) attacks, the concept of capability for access control isintroduced. The novelty of this model is that, it presents an integratedapproach of authentication and access control for IoT devices. Theresults of other related study have also been analyzed to validate andsupport our findings. Finally, the proposed protocol is evaluated byusing security protocol verification tool and verification results showsthat IACAC is secure against aforementioned attacks. This paper alsodiscusses performance analysis of the protocol in terms of computationaltime compared to other existing solutions. Furthermore, this paper addresseschallenges in IoT and security attacks are modelled with the use casesto give an actual view of IoT networks.

Identity Authentication and Capability Based Access Control (IACAC) for the Internet of Things

The sustainable humanitarian supply chain (SHSC) has been the subject of research and debate over recent years. The aim of the paper is to provide an SHSC definition, propose an SHSC structure and validate it empirically. A unique contribution of the present study is an attempt to delineate humanitarian supply chain (HSC) management from commercial supply chain management and further discuss the HSC from the point of view of sustainability. We identify three important characteristics of a HSC network: agility, adaptability and alignment, and further explore possible linkages using extant literature and interpretive structural modelling (ISM). We further test the constructs using confirmatory factor analysis. In this way we attempt to answer long-pending calls from past researchers to contribute to the existing theories of HSC and identify further research directions based on the limitations of the present study.

The sustainable humanitarian supply chain design: agility, adaptability and alignment

A method of securing communications in an RFID system including a reader and an RF tag having a memory configured to store information comprises sending, from the reader, a message to the tag; the tag, in response to the message, generating a challenge value and sending the challenge value to the reader; in any order: the reader performing a mathematical operation on the challenge value based upon a key value to generate a challenge reply and sending the challenge reply to the tag and the tag independently computing a challenge response based on the key value and mathematical operation; the tag comparing the challenge response computed by the tag with the challenge reply sent by the reader; and the tag authenticating the reader if the challenge response matches the challenge reply. An RFID system including an RFID tag and a reader are configured to perform the above steps.

Securing disaster supply chains with cryptography enhanced RFID

Summary We present a concept for the realization of asymmetric cryptographic techniques in light-weight cryptographic devices and describe an implementation based on elliptic curve cryptography which can be used for authentication in mass applications of RFID tags. Our schemes offer advantages in large decentralized applications with many unobservable readers in the field over previous solutions. Moreover, using public key techniques cryptographic protocols that protect the privacy of the tag bearer can be easily implemented.

Using Elliptic Curves on RFID Tags

The invention relates to an RFID tag, which comprises a receiving means, a first and a second verification means, and a transmitting means. The receiving means is designed to receive a challenge message sent by an RFID reading device. Said challenge message comprises a challenge data set, which has a digital certificate issued for the RFID reading device by a certification authority and signed by means of a private key of the certification authority and which has a request message, and a digital signature at least of the request message, which digital signature is generated by means of a private key of the RFID reading device. The first verification means is designed to verify the digital certificate by means of a public key of the certification authority. The second verification means is designed to verify the digital signature by means of a public key of the RFID reading device. The transmitting means transmits a response message to the RFID reading device if the certificate and the digital signature are verified. By verifying the challenge message, the RFID tag can ensure that the RFID tag transmits a response message only to such a requesting RFID reading device that is actually authorized to communicate with said RFID tag.

The method involves providing utilization-permutation fixed by the block cipher and the utilization key (101) and providing multiple dummy-permutations (102), which are fixed by a dummy-key, the block cipher or the inverse of the block cipher. The dummy-permutations are provided such that each chain-linking of the dummy-permutation produces an inverse image set of the block cipher. Independent claims are included for the following: (1) a computer program product for executing the method; and (2) a device for use in a processor for securing a block cipher against template-attacks.

A method and a configuration are described for mutual authentication of two data processing units. The mutual authentication of two data processing units is normally carried out in two separate authentication processes, which are carried out successively. A challenge and response method is normally used. For this purpose, a first challenge is sent from a first data processing unit to a second data processing unit, which transmits a first response back. A second response is produced by the first data processing unit, and is transmitted to the second data processing unit.
