A system includes at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to receive a plurality of doubly-encrypted secret parts that were encrypted using at least a public key belonging to a public/private keypair. The at least one processor is also configured to decrypt each of the plurality of doubly-encrypted secret parts into a corresponding singly-encrypted secret part using a private key belonging to the public/private keypair. The at least one processor is also configured to decrypt each corresponding singly-encrypted secret part into a corresponding secret part. A secret is reconstructed from a quantity of corresponding secret parts that is a subset of a total number of secret parts. The public key, the private key, or both are rotated by creating a new version of the public key, the private key, or both.

Doubly-encrypted secret parts allowing for assembly of a secret using a subset of the doubly-encrypted secret parts

A system includes at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to encrypt each secret part of at least one set of secret parts into a corresponding singly-encrypted secret part. The at least one processor is also configured to encrypt each corresponding singly-encrypted secret part into a corresponding doubly-encrypted secret part using a corresponding at least one public key, each public key belonging to a corresponding one of at least one public/private keypair. At least a subset of the secret parts of the at least one set of secret parts are used to reconstruct a secret.
