WebIf hardware faults are introduced during the application of the Chinese Remainder theorem, the RSA private keys can be discovered. Weba new electromagnetic fault-injection attack on a capsu-lated, rear-side decapsulated, and front-side decapsulated microcontroller. This article is the ﬁrst article that dis-cusses concrete results of optical and EM fault-injection attacks on CRT-based RSA. All attacks have been per-formed at low cost. This article is organized as follows. WebAbstract. Nowadays RSA using Chinese Remainder Theorem (CRT) is widely used in practical applications. However there is a very powerful attack against it with a fault injection during one of its exponentiations. Many countermeasures were proposed but almost all of them are proven to be insecure. paper temporary shelter
