/Dev/Random PRNG in Linux Questioned

The sanctity of the dev/random random number generator used in the Linux kernel has been a hot-button issue for more than a month. A petition posted to change.org in September to remove RdRand from dev/random, for example, was met with fury from Linus Torvalds who called the developer who posted ...

CryptoLocker Ransomware demands $300 or Two Bitcoins to decrypt your files

If you're a daily computer user, you're likely aware of all the threats you face every day online in the form of viruses and malware. CryptoLocker, a new ransomware malware, began making the rounds several months ago. This ransomware is particularly nasty because infected users are in danger of...

CVE-2013-5915

CVE-2013-5915 concerns PolarSSL prior to 1.2.9, where the RSA-CRT Montgomery multiplication was not implemented securely, enabling a timing side-channel attack to potentially recover RSA private keys. Public references in connected docs show厂 PolarSSL advisories and Fedora/OpenVAS entries noting ...

FreeBSD : polarssl -- Timing attack against protected RSA-CRT implementation (ccefac3e-2aed-11e3-af10-000c29789cb5)

PolarSSL Project reports : The researchers Cyril Arnaud and Pierre-Alain Fouque investigated the PolarSSL RSA implementation and discovered a bias in the implementation of the Montgomery multiplication that we used. For which they then show that it can be used to mount an attack on the RSA key...

In Wake of Latest Crypto Revelations, 'Everything is Suspect'

So now that RSA Security has urged developers to back away from the table and stop using the maligned Dual Elliptic Curve Deterministic Random Bit Generation Dual EC DRBG algorithm, the question begging to be asked is why did RSA use it in the first place? Going back to 2007 and a seminal...
