Enough Polynomials and Linear Algebra to Implement Kyber

I was once talking with a mathematician and trying to explain elliptic curve cryptography. Eventually, something clicked and they went "oh, that! I think there was a chapter about it in the book. You made a whole field out of it?" Yes, in cryptography we end up focusing on a very narrow slice of...

kernel: net/sched: sch_fq: fix integer overflow of "credit"

An integer overflow flaw was found in the Linux kernel network fair-queueing scheduler in the way the initial per-flow credit is set. If a configuration provides an excessively large initial quantum, the credit value can overflow to a negative number, leading to excessive scheduling and soft...

You Can’t Rush Post-Quantum-Computing Cryptography Standards

I just read an article complaining that NIST is taking too long in finalizing its post-quantum-computing cryptography standards. This process has been going on since 2016, and since that time there has been a huge increase in quantum technology and an equally large increase in quantum understandi...

The vulnerability of the cgi-bin/hosts_dns.tcl component of the Gaia Portal web interface allows a perpetrator to execute arbitrary commands on the Quantum Security Gateways and Quantum Appliances operating systems.

The vulnerability of the cgi-bin/hostsdns.tcl web interface for configuring the Gaia Portal on the operating system of Quantum Security Gateways and Quantum Appliances is related to the failure to eliminate special elements used in the operating system’s command processing when handling the...
