The existing intentional electromagnetic interference (IEMI) fault injection method based on continuous sinusoidal wave has a difficulty in injecting faults at a specific operation or time. This means that the obtained faulty outputs do not always satisfy a specific condition (e.g., time or number of error bytes) for performing fault analysis such as differential fault analysis (DFA). This paper presents...
This paper presents a new intentional electromagnetic interference (IEMI) fault injection method that can be used to inject transient faults into cryptographic operations with precise timing from a distance. Such IEMI fault injection can be used for performing fault analysis attacks, such as differential fault analysis and fault sensitivity analysis, and therefore it could pose a severe threat to...
Fault injection based on intentional electromagnetic interference (IEMI) is attracting considerable attention in the field of physical attacks on cryptographic devices due to its non-contact and non-invasive nature. This paper explores the relations between injection intensity and fault occurrence during IEMI-based fault injection. The basic idea in this type of attack is to generate a map of the...
This paper presents a new type of intentional electromagnetic interference (IEMI) which causes information leakage in electric devices without disrupting their functions or damaging their components. Such IEMI could pose a severe threat to a large number of electric devices with cryptographic modules since it can be used for performing fault injection attacks, which in turn allows for obtaining faulty...
In this paper, we introduce a new type of intentional electromagnetic interference (IEMI) which causes information leakage in electrical devices without disrupting their operation or damaging their physical structure. Such IEMI could pose a severe threat to a large number of electrical devices with cryptographic modules since it can be used for performing fault injection attacks, which in turn allows...
This paper presents a new type of intentional electromagnetic interference (IEMI) which causes information leakage from cryptographic ICs (Integrated Circuits). As a recent threat, it is known that faults in cryptographic ICs such as Advanced Encryption Standard (AES) have significant influence on leakage of sensitive information. AES is a block cipher standardized by NIST (National Institute of Standards...
Recently, it has been known that electromagnetic radiation from electrical device leaks internal information. That is, electromagnetic radiation contains information. Especially, it causes serious problem for cryptographic modules if electromagnetic radiation contains secret information. Therefore many studies have been made on power/electromagnetic analysis attacks, which extract secret keys from...
