Classification: CPC H | IPC H

Claim 19:
20. A computing system comprising a processor and a memory, wherein the processor is configured to:
receive a tokenized message;
generate a plurality of shares from the tokenized message using a message sharing algorithm of a secret sharing scheme;
signcrypt a first share of the plurality of shares using a public/private key pair associated with a shared secret provider computing system and a public key of a first share-holder in a share-holders list to generate a first signcrypted share of a plurality of signcrypted shares, wherein authenticity and data integrity of the first signcrypted share of the plurality of signcrypted shares is determined based on a public key of the public/private key pair associated with the shared secret provider computing system and a public/private key pair associated with the first share-holder in the plurality of signcrypted shares;
verify a signature of the first signcrypted share of the plurality of signcrypted shares using a dealer's public key and the public/private key pair associated with the first share-holder;
unsigncrypt the first signcrypted share using an unsigncryption algorithm;
generate a verification message and presenting the verification message to the first share-holder of the share-holders list; and
reconstruct the tokenized message using a message reconstruction algorithm when a threshold amount required for the secret sharing scheme is met.
