Remote Timing Attacks Are Practical
Timing attacks are usually used to attack weak computing devices such as smartcards. We show that timing attacks apply to general software systems. Specifically, we devise a timing attack against OpenSSL. Our experiments show that we can extract private keys from an OpenSSL-based web server running on a machine in the local network. Our results demonstrate that timing attacks against network se...
متن کاملRemote Timing Attacks are Still Practical ? Billy
For over two decades, timing attacks have been an active area of research within applied cryptography. These attacks exploit cryptosystem or protocol implementations that do not run in constant time. When implementing an elliptic curve cryptosystem with a goal to provide side-channel resistance, the scalar multiplication routine is a critical component. In such instances, one attractive method ...

متن کاملTiming attacks against OpenSSL
OpenSSL is the most widely used open source SSL/TLS implementation on the internet and an immense amount of sensitive communication is trusted to be secured by it. The related cryptographic algorithms themselves are indeed very secure. However implementing the models in hardware or software introduces new kinds of channels that are not present in the mathematical model, but which can nonetheles...
متن کاملCache-Timing Template Attacks
Cache-timing attacks are a serious threat to security-critical software. We show that the combination of vector quantization and hidden Markov model cryptanalysis is a powerful tool for automated analysis of cache-timing data; it can be used to recover critical algorithm state such as key material. We demonstrate its effectiveness by running an attack on the elliptic curve portion of OpenSSL (0...
