Side - Channel Monitoring of Contactless Java Cards
Smart cards are small, portable, tamper-resistant computers used in securitysensitive applications ranging from identi_cation and access control to payment systems. Side-channel attacks, which use clues from timing, power consumption, or even electromagnetic (EM) signals, can compromise the security of these devices and have been an active research area since 1996. Newer contactless” cards comm...
متن کاملEM Side-Channel Attacks on Commercial Contactless Smartcards Using Low-Cost Equipment
We introduce low-cost hardware for performing non-invasive side-channel attacks on Radio Frequency Identi cation Devices (RFID) and develop techniques for facilitating a correlation power analysis (CPA) in the presence of the eld of an RFID reader. We practically verify the e ectiveness of the developed methods by analysing the security of commercial contactless smartcards employing strong cryp...
متن کاملFlexible Visual Display Units as Security Enforcing Component for Contactless Smart Card Systems
Today, one existing class of RFID systems are based on ISO 14443 (Proximity Coupling). This is the standard for RF-interfaces of contactless smart card systems. Contactless RF interfaces of smart cards are very often regarded as less secure than contact based smart cards. This tenor may be changed based on our new approach. Therefore we suggest to establish secure password authenticated wireles...
متن کامل"On-Card" User Authentication for Contactless Smart Cards based on Gesture Recognition
Smart cards are widely used for security purposes. To protect smart cards against misuse an authentication process (e.g. entering a pin or password) is necessary. Due to missing input interfaces “on-card”, an external terminal is required to input the password. Unfortunately the required external hardware (e.g. keypads, etc.) opens up new security issues by being vulnerable against attacks like...
متن کاملSide-Channel Analysis of Cryptographic RFIDs with Analog Demodulation
As most modern cryptographic Radio Frequency Identification (RFID) devices are based on ciphers that are secure from a purely theoretical point of view, e.g., (Triple-)DES or AES, adversaries have been adopting new methods to extract secret information and cryptographic keys from contactless smartcards: Side-Channel Analysis (SCA) targets the physical implementation of a cipher and allows to re...
