In cryptography a blind signature, as introduced by David Chaum, is a form of digital signature in which the content of a message is disguised (blinded) before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature. Blind signatures are typically employed in privacy-related protocols where the signe… WebSep 10, 2024 · The enclave decrypts the input and then applies cryptographic blinding to the input data and the model parameters.
