WebNov 18, 2024 · NIST Standards gives advice on what a cryptoperiod should be set to. A cryptoperiod is the time span that a key can be used for its given purpose before it must be renewed or, preferably, replaced with a new key. For asymmetric-key pairs, each key has its own cryptoperiod. Web1=2. Therefore, we can apply Simon’s algorithm to get k. 5 Conclusion We have showed that symmetric cryptography is far from ready for the post quantum world. We have found …

Sorted by: 2. Theoretically as pointed out by @CodesInChaos there is no need to rotate keys as long as they remain secret. Also as @CodesInChaos points out, you need to architect the system for key rotation in the event of key compromise. The best way to do that is to build key rotation into the app and operational tooling, and then ...
