| Popis: | Modern web applications using advanced cryptographic methods may need to calculate a large number of modular exponentiations. Performing such calculations in the web browser efficiently is a known problem. We propose a solution to this problem based on outsourcing the computational effort to untrusted exponentiation servers. We present several efficient outsourcing protocols for different settings and a practical implementation consisting of a JavaScript client library and a server application. Compared to browser-only computation, our solution improves the overall computation time by an order of magnitude. |
