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 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.
