Trump Order Sets 2030 Deadline for Federal Post-Quantum Crypto Migration

President Trump signed an executive order on June 22 setting hard deadlines for federal agencies to move high-value assets and high-impact systems to post-quantum cryptography. Key establishment must move by December 31, 2030; digital signatures by December 31, 2031. EO 14409 leaves national...

openssl: OpenSSL TLS 1.3 server may choose unexpected key agreement group

A key group selection preference flaw has been discovered in OpenSSL. An OpenSSL TLS 1.3 server may fail to negotiate the expected preferred key exchange group when its key exchange group configuration includes the default by using the "DEFAULT" keyword. A less preferred key exchange may be used...

Post-Quantum Cryptography Is Coming, but Your DNS Might Not Be Ready

Learn why crypto-agility depends not just on adopting the right standards, but on maintaining a clear, unified view of your DNS environment before the migration begins...

Certification of Network Quantum Sensing

The distribution of quantum sensors on quantum networks is a key enabler of quantum technologies in interferometry, gravimetry, timekeeping, biological monitoring, and beyond. Yet, guaranteeing the security of these distributed sensors over noisy, insecure networks remains a formidable challenge...

Hardware-Aware QAOA for Honeypot Traffic Partitioning on 100+ Qubit IBM Quantum Processors

Denial-of-service DoS and distributed denial-of-service DDoS mitigation requires separating malicious traffic from benign traffic while minimizing disruption to legitimate users. Prior work proposed mapping honeypot traffic partitioning to a weighted MaxCut problem and solving the resulting graph...

The Clock Is Already Ticking: Why Post-Quantum Cryptography Can’t Wait

There is a question I have been hearing more and more from CISOs, compliance officers, and security architects over the past year. It does not start with "we had a breach" or "we failed an audit." It starts with something that sounds almost philosophical: " Are we quantum-safe?" A year ago, that...
