1. A computer-implemented method, comprising:

  • obtaining a request to perform an operation, the performance of which involves an encryption operation using a first cryptographic key specified in the request;

    causing a device to perform the encryption operation using the first cryptographic key;

    determining, based at least in part on a stochastic process, to cause a counter to be updated; and

    based at least in part on the counter satisfying a set of key rotation criteria, causing the first cryptographic key to be replaced with a second cryptographic key, the set of key rotation criteria having a probability of being satisfied that is associated with a frequency of key rotation.
