Abstract
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.
