WebMar 17, 2024 · In cryptography, blinding is a concept related to confidentiality. In particular, it refers to the capacity of outsourcing the computation of a mathematical function, e.g., y = f ( x ), to an (untrusted) server while ensuring that the values of the real input ( x) and the real output ( y) are kept hidden from the server. Webtion, cryptographic blinding, interspersed with accelerator-based computation. Origami partitions the ML model into multiple partitions. The ﬁrst partition receives the encrypted user input within an SGX enclave. The enclave decrypts the input and then applies cryptographic blinding to the input data and the model parameters.
