A large chunk of the global economy now rests on public key cryptography. We generally agree that with long enough keys, it is infeasible to crack things encoded that way. Until such time as it isn’t, that is. Researchers published a paper a few years ago where they cracked a large number of keys in a very short amount of time. It doesn’t work on any key, as you’ll see in a bit, but here’s the interesting part: they used an undescribed algorithm to crack the codes in a very short amount of time on a single-core computer. This piqued …read more
A team of researchers has found vulnerabilities in implementations of the Internet Key Exchange version 1 (IKEv1) protocol in firewalls and other networking gear that support IPsec VPN tunnels. If exploited, the flaw can allow attackers to bypass auth… Continue reading IKEv1 Vulnerabilities Break IPsec VPN Security in Cisco, Huawei, ZyXEL Gear
Encryption is one of the pillars of modern-day communications. You have devices that use encryption all the time, even if you are not aware of it. There are so many applications and systems using it that it’s hard to begin enumerating them. Ranging from satellite television to your mobile phone, from smart power meters to your car keys, from your wireless router to your browser, and from your Visa to your Bitcoins — the list is endless.
One of the great breakthroughs in the history of encryption was the invention of public key cryptography or asymmetrical cryptography in the 70’s. …read more
