In this thesis, we study the algebraic structure underlying number-theoretic pseudorandom functions. Specifically, we define an algebraic framework that translates the pseudorandomness of a particular form of functions into a simple algebraic property. The resulting generic framework encompasses most of existing constructions and naturally extends to related primitives, such as related-key secure, aggregate, and multilinear pseudorandom functions. This framework holds under a family of MDDH assumptions, that contains especially different classical assumptions, such as DDH, DLin, or k-Lin. Therefore, setting accordingly the parameters in the constructions, our framework can be used to construct secure pseudorandom functions (or related primi...
