DefCon 2012 - Near-Field Communication / RFID Hacking - MillerMichael Smith
The document explores the NFC attack surface by examining NFC protocols and fuzzing the NFC stack on two devices. It finds that some phones can be forced to parse content like images, contacts, and open web pages without user interaction through NFC technologies. In some cases, full control of the phone is possible, allowing theft of data and sending of messages/calls. Proper understanding of NFC and its protocols is needed to analyze risks introduced by the inclusion of NFC functionality on mobile devices.
Near Field Communication (NFC) is a short-range wireless technology that allows data exchange between devices within close proximity. NFC operates at 13.56 MHz and has a maximum range of about 4 cm. It can be used for contactless payments, data sharing, and connecting electronic devices like accessing a building. NFC provides security through its very short transmission range which requires devices to be in close physical contact to communicate, preventing unwanted access. It also uses protocols that prevent collisions when multiple devices transmit simultaneously.
NFiD: An NFC based system for Digital Business CardsIRJET Journal
The document proposes an NFC-based system to replace paper business cards with digital business cards that are instantly transferred to a user's smartphone when they scan another person's NFC tag. It describes the technical aspects of using NFC technology to store and share contact information digitally. An Android app is presented that allows users to view, save, and manage contacts scanned from NFC tags and stored in the cloud.
The NFC technology evolved from contactless radio frequency identification (RFID). The RFID transmission range can reach several meters or even tens of meters. It can only read and determine information, and NFC technology emphasizes information exchange. Near field, communication is operated at a frequency of 13.56 MHz within a distance of 20 cm, and its transmission speed is 106 Kbit/s, 212 Kbit/s, or 424 Kbit/s.
This document proposes a lightweight secure framework for Near Field Communication (NFC) tags that ensures data integrity and authentication. The framework uses cryptographic hashing and digital signatures to verify that data stored on NFC tags has not been altered. It involves generating a hash of the data to store, encrypting the hash with a private key, and writing both to the NFC tag. When reading the tag, the framework re-computes the hash and decrypts the stored hash to verify a match, confirming the data has not been modified. This framework aims to address security issues with NFC tags like eavesdropping, data corruption, and physical theft that could compromise existing payment and identification systems.
Near Field Communication : Tap and KnowIRJET Journal
This document discusses using Near Field Communication (NFC) technology to provide tourist information to users. It describes how NFC allows information to be transferred between two NFC-enabled devices simply by tapping them together.

The system is divided into modules for reading and writing NFC tags, booking tickets, and booking buses directly from the location tags. Benefits mentioned include providing accurate location information to tourists and enabling services like ticketing and transportation booking with just a tap.
This document provides an overview of Near Field Communication (NFC) technology. It discusses that NFC allows for short-range wireless communication between devices when they are touched or brought within close proximity. The document outlines the history and development of NFC, how NFC works using readers and tags, comparison to other wireless technologies, example applications such as mobile payments, and the benefits and future of NFC technology.

Accessory authentication on NFC enabled product using three pass AES algorithmIRJET Journal
This document proposes a model for authenticating accessories for NFC-enabled products using AES encryption. It involves the following:
1. Establishing communication between an NFC reader in the product and an NFC tag in the accessory.
2. Performing mutual authentication between the reader and tag through a three-pass AES encryption algorithm (AES-128) run in either AES-ECB or AES-CBC mode.
3. Authenticating that the reader and tag are paired counterparts from the same company, ensuring the accessory is genuine and high quality. This protects brands from counterfeits.

The document discusses how crating can benefit puppies. It notes that puppies are descended from wolves that found comfort in dens, and modern dogs also find solace in their own space. When not being watched, puppies should be confined to an area like a crate to prevent accidents. Owners must take puppies out frequently and praise them for relieving themselves in the proper place. Crating can also provide a sanctuary for over-excited puppies and protection from young children by enforcing quiet time.
