Stealing Keys from PCs Using a Radio: Cheap Electromagnetic Attacks on Windowed Exponentiationacks extract decryption keys using a very low measurement bandwidth (a frequency band of less than 100?kHz around a carrier under 2?MHz) even when attacking multi-GHz CPUs..We demonstrate the attacks’ feasibility by extracting keys from GnuPG (unmodified ElGamal and non-blinded RSA), within seconds,

Exclusive Exponent Blinding May Not Suffice to Prevent Timing Attacks on RSAdely believed that exponent blinding would prevent any timing attack on RSA. At cost of significantly more timing measurements this paper extends the before-mentioned attacks to RSA with CRT when Montgomery’s multiplication algorithm and exponent blinding are applied. Simulation experiments are cond

Who Watches the Watchmen?: Utilizing Performance Monitors for Compromising Keys of RSA on Intel Platministic branch predictor behavior due to their key-dependent input sequences. We show that branch predictors can also leak information through the hardware performance monitors which are accessible by an adversary at the user-privilege level. This paper presents an iterative attack which target the

Improved Cryptanalysis of the DECT Standard Cipheronfidentiality of the communications. In this paper we present an improved cryptanalysis approach which is more effective than the Nohl-Tews-Weinmann (NTW) attack and requires four times less plaintext material. Under the best conditions, our known plaintext attack requires only 3?min of communicati
