Your IoT Devices Will Outlive Your Cryptography (opens in new tab)  🐍python

A smart meter installed today has a 15-year service life. A medical device implanted this year may still be transmitting data in 2040. An industrial sensor bolted into a factory floor will be there long after the engineer who commissioned it has moved on. The certificates you issue to those devices today are signed with ECDSA or RSA. Those algorithms are secure against classical computers. They are not secure against a sufficiently large quantum computer running Shor's algorithm. NIST's own t...
