Three Questions for Billy Brumley on the OpenSSL Timing Attack

Timing attacks have been a problem for designers of cryptosystems–as well as for people implementing those systems–for a long time. They’ve plagued just about every popular system, and although practical attacks have been demonstrated many times, the problem and what can be done to defend against...

OpenSSL leaks ECDSA private key through a remote timing attack

Overview The OpenSSL ladder implementation for scalar multiplication of points on elliptic curves over binary fields is susceptible to a timing attack vulnerability. This vulnerability can be used to steal the private key of a TLS server that authenticates with ECDSA signatures and binary curves...
