Attack on Old ANSI Random Number Generator

Almost 20 years ago, I wrote a paper that pointed to a potential flaw in the ANSI X9.17 RNG standard. Now, new research has found that the flaw exists in some implementations of the RNG standard. Here's the research paper, the website -- complete with cute logo -- for the attack, and Matthew...

DUHK Attack Exposes Gaps in FIPS Certification

Despite the obligatory logo and clever name, this week’s assault on crypto, the so-called DUHK attack Don’t Use Hardcoded Keys, isn’t likely to be part of many threat models. Though the attack can be used to passively decrypt VPN and encrypted browser traffic, it relies on a host of implementatio...

DUHK Attack against Fortinet Products

When devices use ANSI X9.31 RNG which was removed from the list of FIPS-approved random number generation algorithms in January 2016 to generate cryptographic key under a static seed and under use with long-lived security tunnels like SSL/TLS/SSH/IPSec, such devices are vulnerable to the DUHK...
