WebIt is the first protocol to use cryptographic blinding to enable subscription services. The protocol prevents the service from tracking the behavior of its customers, while protecting the service vendor from abuse due to simultaneous or cloned use by a single subscriber. Our basic protocol structure and recovery protocol are robust against ... In cryptography, blinding is a technique by which an agent can provide a service to (i.e., compute a function for) a client in an encoded form without knowing either the real input or the real output. Blinding techniques also have applications to preventing side-channel attacks on encryption devices.

WebBlinding is a concept in cryptography that allows a client to have a provider compute a mathematical function y = f ( x ), where the client provides an input x and retrieves the corresponding output y, but the provider would learn about neither x nor y. 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.
