It’s Not Too Early to Start Thinking About Post-Quantum Security

In networking and communication, information security is absolutely necessary when transmitting over any untrusted medium, especially the Internet. Cisco is tracking all of the solutions in this area and will bring to market a flexible solution that will enable our customers to use whatever PQ secure solution they feel more appropriate for them.

ETSI/IQC’s 4th Workshop on Quantum-Safe Cryptography

Quantum computers could break commonly used public key algorithms, which would affect cryptography used today. For that reason, there has been great attention on quantum safe crypto recently. We have blogged about it in numerous occasions [1], [2] , [3]. In that context, last week the 4th ETSI/IQC on Quantum-Safe Cryptography in Toronto, Canada brought […]
