摘要:	安全多方計算（Secure multi-party computation, SMC）的研究主要是針對分散環境下的兩方或多方在計算一個約定函數問題時，能夠在不透漏彼此私有資料的情況下，不失安全性的計算出結果。smcSL 爲一個安全多方計算腳本語言，是為了能夠自動化使用符合安全需求的函式庫（SMC-Protocol）而發展出來的。目前此腳本語言runtime以Ruby執行，且產生盡量多的smc運算來確保安全性。我們的研究將針對以上兩個限制去改寫編譯器，讓它能夠產生C++目的碼並在不失安全性的前提下改寫expression運算，進而減少smc運算的數量以達到效率的提升。由於數學中二元運算存在Rule1:交換律和結合律、Rule2:分配律等性質，使得expression的改寫能不影響運算結果。編譯器會透過重排順序、提出因數等方式改寫expression，讓不必要的 smc二元運算子降為local運算，使得smcSL的效能獲得改進。 Secure multiparty computation (SMC) involves computing functions with inputs from two or more parties in a distributed network while ensuring that no additional information, other than what can be inferred from each participant`s input and output, is revealed to parties not privy to that information. Recently, language-based tools are emerging to better support the systematic development of SMC protocols. In particular, smcSL is a scripting language developed by our laboratory for automating the development of complex protocols for an information-theoretical approach to secure multiparty computation. This scripting language models the participating parties in a peer-to-peer symmetric manner that each party holds their private data as well as any intermediate results jointly. The smcSL language enables users to express their requirements of "the right to use a piece of data" in a simple yet abstract way and its compiler can detect any potential breaches of those security requirements specified in a user script. However, for safety purpose, the compiler generates object code by using a lot of SMC protocols. This conservative strategy leads to inefficient runtime performance. This thesis investigates how to apply compiler optimization techniques such as algebraic simplification to improve the runtime performance of generated code. Specifically, we enhance the compiler with an optimization module that uses associative, commutative and distributive law to rewrite computation expressions so that unnecessary invocations of SMC protocols will be replaced by execution of local computations. As a result, the computation and communication cost of generated code will be reduced explicitly.
