Automated experimental setup for EM cartography to enhance EM attacks

Side-channel attacks are a real threat, exploiting and revealing the secret data stored in our electronic devices just analyzing the leaked information of the cryptographic modules during their normal encryption/decryption operations. In this sense, electromagnetic attacks have been posed as one of the most powerful attacks, retrieving the secret information by analyzing the existing relation between the leaked electromagnetic radiation and the data being processed. These attacks are known as ElectroMagnetic (EM) attacks and a extremely critic point for their success is the EM probe positioning. In this paper, an automated experimental setup for EM cartography is described to enhance EM attacks and to help hardware designers to detect the possible information leakage flaws, as well as to determine the security level reached by the hardware implementations against EM attacks

3D near Field Acquisition System

Tato práce se zabývá přestavením 3D tiskárny na přístroj umožňující automaticky snímat elektromagnetický postranní kanál vycházející z mikroprocesoru (čipové karty). Cílem je na přístroji signál pomocí digitálního osciloskopu naměřit a sestavit 3D graf, který bude zobrazovat množství vyzářeného signálu v jednotlivých místech mikroprocesoru. Literární rešerše se zabývá elektromagnetickým postranním kanálem a způsoby analýzy naměřených dat, zejména pak diferenciální elektromagnetickou analýzou. Praktická část práce navazuje sestavením přístroje na automatizované měření, dále pak programem, který řeší komunikaci mezi počítačem, osciloskopem, pozicovacím přístrojem a čipovou kartou. Závěrečná část práce je věnována analýze a dešifrování naměřených dat. Výsledek práce nabízí levnou alternativu pro již existující drahé přístroje měřící postranní elektromagnetické záření.This thesis describes rebuilding a 3D printer into a device that automatically captures electromagnetic side channel of a microprocessor (smart card). The aim is to measure the signal emitted by a smart card using a digital oscilloscope and to plot a 3D graph displaying the amount of signal radiated by each part of the smart card. The theoretical part of this paper deals with electromagnetic side channel and methods of analysis of measured data, particularly with differential electromagnetic analysis. The practical part of the paper follows with building a positioning device for automated measurements, then with a program that handles communication between a computer, the oscilloscope, the positioning device and the smart card. Finally, the program analyses the measured data. The resulting device offers a cheap alternative to already existing expensive devices measuring electromagnetic emissions

EM Attack Is Non-Invasive? - Design Methodology and Validity Verification of EM Attack Sensor

This paper presents a standard-cell-based semi-automatic design methodology of a new conceptual countermeasure against electromagnetic (EM) analysis and fault-injection attacks. The countermeasure namely EM attack sensor utilizes LC oscillators which detect variations in the EM field around a cryptographic LSI caused by a micro probe brought near the LSI. A dual-coil sensor architecture with an LUT-programming-based digital calibration can prevent a variety of microprobe-based EM attacks that cannot be thwarted by conventional countermeasures. All components of the sensor core are semi-automatically designed by standard EDA tools with a fully-digital standard cell library and hence minimum design cost. This sensor can be therefore scaled together with the cryptographic LSI to be protected. The sensor prototype is designed based on the proposed methodology together with a 128bit-key composite AES processor in 0.18um CMOS with overheads of only 1.9% in area, 7.6% in power, and 0.2% in performance, respectively. The validity against a variety of EM attack scenarios has been verified successfully
