Probing Attacks on Tamper-Resistant Devices
نویسندگان
چکیده
This paper describes a new type of attack on tamper-resistant cryptographic hardware. We show that by locally observing the value of a few RAM or adress bus bits (possibly a single one) during the execution of a cryptographic algorithm, typically by the mean of a probe (needle), an attacker could easily recover information on the secret key being used; our attacks apply to public-key cryptosystems such as RSA or El Gamal, as well as to secret-key encryption schemes including DES and RC5.

Fast Primitives for Internal Data Scrambling in Tamper Resistant Hardware
Although tamper-resistant devices are specifically designed to thwart invasive attacks, they remain vulnerable to micro-probing. Among several possibilities to provide data obfuscations, keyed hardware permutations can provide compact design and easy diversification. We discuss the efficiency of such primitives, and we give several examples of implementations, along with proofs of effectively l...
متن کاملLow Cost Attacks on Tamper Resistant Devices
There has been considerable recent interest in the level of tamper resistance that can be provided by low cost devices such as smartcards. It is known that such devices can be reverse engineered using chip testing equipment, but a state of the art semiconductor laboratory costs millions of dollars. In this paper, we describe a number of attacks that can be mounted by opponents with much shallow...
متن کاملOn the Duality of Probing and Fault Attacks
In this work we investigate the problem of simultaneous privacy and integrity protection in cryptographic circuits. We consider a white-box scenario with a powerful, yet limited attacker. A concise metric for the level of probing and fault security is introduced, which is directly related to the capabilities of a realistic attacker. In order to investigate the interrelation of probing and fault...
متن کاملComputationally Sound Proofs of Security for a Key Management API extended abstract
Security solutions for information systems are increasingly making use of tamper-resistant cryptographic devices, whether they are smartcards carried by commuters on a mass transit system, or high-throughput Hardware Security Modules in a bank ATM transaction processing processing facility. Over the last few years we have been analysing the key management APIs of such tamper-resistant devices. ...
متن کاملTemplate Attacks on Different Devices
Template attacks remain a most powerful side-channel technique to eavesdrop on tamper-resistant hardware. They use a profiling step to compute the parameters of a multivariate normal distribution from a training device and an attack step in which the parameters obtained during profiling are used to infer some secret value (e.g. cryptographic key) on a target device. Evaluations using the same d...
