Skyscraper: Fast Hashing on Big Primes
Transactions on Cryptographic Hardware and Embedded SystemsArithmetic hash functions defined over prime fields have been actively developed and used in verifiable computation (VC) protocols. Among those, ellipticcurve- based SNARKs require large (256-bit and higher) primes. Such hash functions are notably slow,

An improved SHA-256 based agent system for web content update management
, 2011 博士在網際網路的環境只使用固定密碼作為驗證身分的機制，會讓系統與使用者暴露在危險中，因此我們以時戳(Time Stamp)結合了SHA-256將其改良為Time Stamp SHA-256(TSSHA-256)可以用來產生動態密碼(one-time password,OTP)，透過OTP可以加強出版網頁時的安全性，而主機端的代理人系統，會在更新網頁資料前先透過TSSHA-256來驗證所接收資料的完整性，當資料通過檢測才會讓網頁內容出版到網站主機的相關目錄，並且在更新網頁之後再次使用 TSSHA ...
