Recent work on proof-based verifiable computation has resulted in built systems that employ tools from complexity theory and cryptography to address a basic problem in systems security: allowing a local computer to outsource the execution of a program while providing the local computer with a guarantee of integrity and the remote computer with a guarantee of privacy. However, support for programs that use RAM and control flow has been problematic. State of the art systems either restrict the use of these constructs (e.g., requiring static loop bounds), incur sizeable overhead on every step, or pay tremendous costs when the constructs are invoked. This paper describes Buffet, a built system that solves these problems by providing inexpensive “alacarte” RAM and dynamic control flow. Buffet composes an elegant prior approach to RAM with a novel adaptation of techniques from the compilers literature. Buffet allows the programmer to express programs in an expansive subset of C (disallowing only “goto” and function pointers), can handle essentially any example in the verifiable computation literature, and achieves the best performance in the area by multiple orders of magnitude.
