Security Highlight: Exploiting Persistent Faults In Crypto

By Marc Witteman - 02 Feb, 2023 - Comments: 0

At the most recent CHES workshop, Hossein Hadipour of the Graz University of Technology presented an important step forward in exploiting persistent faults in crypto. Differential Fault Analysis (DFA) is a well-known attack class that can lead to the compromise of a secret key when faults are injected during the execution of a cryptographic implementation. However, injecting transient fault... » read more

Hardware Countermeasures Benchmarking against Fault Attacks

By Technical Paper Link - 18 Apr, 2022 - Comments: 0

Abstract "The development of differential fault analysis (DFA) techniques and mechanisms to inject faults into cryptographic circuits brings with it the need to use protection mechanisms that guarantee the expected level of security. The AES cipher, as a standard, has been the target of numerous DFA techniques, where its security has been compromised through different formulations and types of... » read more

Side-Channel Attacks Make Devices Vulnerable

By Brian Bailey - 17 Oct, 2016 - Comments: 0

As the world begins to take security more seriously, it becomes evident that a device is only as secure as its weakest component. No device can be made secure by protecting against a single kind of attack. Hypervisors add a layer of separation between tasks making sure that one task cannot steal secrets from another. Protection of the JTAG port is necessary to prevent access underneath the h... » read more
