Are These Pairing Elements Correct?
Susan Hohenberger, Satyanarayana Vusirikala · 2019
Using a set of pairing product equations (PPEs) to verify the correctness of an untrusted set of pairing elements with respect to another set of trusted elements has numerous cryptographic applications. These include the design of basic and structure-preserving signature schemes, building oblivious transfer schemes from "blind" IBE, finding new verifiable random functions and keeping the IBE/ABE authority "accountable" to the user.
