Defend encryption systems against side- channel attacks
From its ancient origin as a tool for protecting sensitive wartime or espionage-related messages, cryptography has become a foundational building-block for securing the systems, protocols, and infrastructure that underpin our modern interconnected world. But the physical mechanisms used in performing encryption and decryption can leak information, making it possible to bypass this security. Pro...
متن کاملProvably Secure Countermeasures against Side-channel Attacks
Side-channel attacks exploit the fact that the implementations of cryptographic algorithms leak information about the secret key. In power analysis attacks, the observable leakage is the power consumption of the device, which is dependent on the processed data and the performed operations. Masking is a widely used countermeasure to thwart the powerful Differential Power Analysis (DPA) attacks. ...
متن کاملCombined Modeling and Side Channel Attacks on Strong PUFs
Physical Unclonable Functions (PUFs) have established themselves in the scientific literature, and are also gaining ground in commercial applications. Recently, however, several attacks on PUF core properties have been reported. They concern their physical and digital unclonability, as well as their assumed resilience against invasive or side channel attacks. In this paper, we join some of thes...
متن کاملSide channel parameter characteristics of code injection attacks
Embedded systems are suggestive targets for code injection attacks in the recent years. Software protection mechanisms, and in general computers, are not usually applicable in embedded systems since they have limited resources like memory and process power. In this paper we investigate side channel characteristics of embedded systems and their applicability in code injection attack detection. T...
