Breaking Smartcards Using Power Analysis

How to Make Smartcards Resistant to Hackers' Lightsabers?

Cracking smartcards has always been a prized hobby, for the academic glory, for fun (ha, breaking the selfclaimed unbreakable...) and for profit (ask the organized crime). State-of-the-art techniques include laser blasts that inject various transient or permanent faults in a program execution, potentially making the smartcard do whatever the attacker wants. After a brief recap of the attack too...

PINPAS: A Tool for Power Analysis of Smartcards

EM 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...

Agent Platform for Wireless Sensor Network with Support for Cryptographic Protocols

This paper deals with a description of wireless sensor networks at the beginning. Further follows the introduction to the agent platform suitable for wireless networks. Mobile code and sensor networks suffer from considerable security problems. Our proposal of countermeasure is based on combination of smartcards with sensor nodes. Smartcards as a tamper resistant devices offer solution for the ...

Enhanced DES Implementation Secure Against High-Order Differential Power Analysis in Smartcards

Since Differential Power Analysis (DPA) on DES in smartcards was firstly published by Kocher et al. in 1999, many countermeasures have been proposed to protect cryptographic algorithms from the attack, of which masking is an efficient and easily implemented method. In this paper, after showing some attacks on Akkar et al. ’s improved DES implementation from FSE’04, we list and prove some basic ...
