Privacy-preserving transaction validation system using secure enclave
A recently granted patent (Publication Number: US12003617B2) discloses a method performed by trusted code of a secure enclave in a computing system to provide evidence that a transaction has been validated. The secure enclave, a feature of the processing unit, stores trusted code in encrypted form and decrypts it for execution using a private key of a public/private keypair. The method involves receiving, decrypting, and validating a transaction, generating an attestation signed with the private key, including a hash of the transaction, and providing it to untrusted code for validating another transaction. This allows the trusted code to rely on the attestation as evidence of validity, preserving the confidentiality of the transaction.
Furthermore, the patent describes a computing system that, during the execution of trusted code in a secure enclave, validates transactions that input an output state of another transaction. The system includes computer-readable storage mediums storing instructions for receiving a signature of attestation from untrusted code, verifying its origin from a secure enclave, coordinating with a notary to determine the consumption of the output state, and indicating the transaction's validity based on specified criteria. This system ensures the secure validation of transactions while maintaining confidentiality and integrity, enhancing the security of computing systems in processing transactions and maintaining distributed ledgers.
