Optical fault induction attacks
WebOne approach is the optical fault injection. Nowadays many manufactures apply countermeasures against fault attacks, but adversaries invent and introduce new … WebSep 1, 2024 · This paper introduces an ARM specific fault injection attack strategy for exploiting embedded systems where externally controlled data is loaded in the program counter (PC) register of the processor, which allows an attacker to control the target's execution flow which eventually will lead to arbitrary code execution on the target. 75 PDF

WebFirst, using optical fault induction attacks as recently publicly presented by Skorobogatov and Anderson \cite {SA}, we present an implementation independent fault attack on AES. This attack is able to determine the complete 128 -bit secret key of a sealed tamper-proof smartcard by generating 128 faulty cipher texts. WebJan 1, 2003 · Illumination of a target transistor causes it to conduct, thereby inducing a transient fault. Such attacks are practical; they do not even require expensive laser …
WebUnlike other classes of fault injection techniques, EMFI-based attacks can, in theory, be carried out non-invasively without requiring physical contact with the victim device. Prior research has demonstrated the viability of EMFIbased attacks against relatively simple, low-frequency, synchronous digital circuits. WebThe first one uses a fault model that induces a fault on only one bit of an intermediate result, hence allowing us to obtain the key by using 50 faulty ciphertexts for an AES-128. The second attack uses a more realistic fault model: we assume that we may induce a …
WebApr 15, 2004 · Unless suitable countermeasures are taken, optical probing may also be used to induce errors in cryptographic computations or protocols, and to disrupt the processor's control flow. It thus... WebOptical Fault Induction Attacks Sergei Skorobogatov, Ross Anderson University of Cambridge, Computer Laboratory (sps32,rja14)@cl.cam.ac.uk Abstract We describe a new class of attacks on secure microcontrollers and smartcards. Illumination of a target transistor causes it to conduct, thereby inducing a transient fault.
WebOptical fault injection attack is a conventional way that aims at extracting the information stored on memories. However, it has not been developed yet using this method to attack …
WebFault injection attacks have proven to be a powerful tool to exploit the implementation weaknesses of cryptographic algorithms. Several techniques perturbing the computation of a cipher have been devised and successfully employed to leak secret information from erroneous results. flying scot edinburgh discount codeWebOptical Fault Induction Attacks.
