AES 與 NESSIE

Abstract

在本篇論文中，我們介紹了先進的加密標準 (AES) 與 NESSIE。在 1997 年 NIST 這個組織發起了一個對稱性加密演算法的徵選程序，NIST 從15 個演算法之中選出了 MARS, RC6TM, Rijndael, Serpent 還有 Twofish 進入最後的徵選階段，最後 NIST 決定提出 Rijndael 為 AES的加密演算法。NESSIE 是由一個歐洲的電腦程序委員會 (IST) 所提出的一個計劃，是一個為期三年的計劃，開始於2000年1月，這個計劃的主要目的希望能夠透過一個透明，公開的程序， 來選出一些經由公開召集方式所提出的密碼學的演算法。這些演算法包括了區塊密碼(block cipher)，流動密碼(stream cipher)，hash 函數，MAC 演算法，電子簽章法，公開金鑰加密法。NESSIE 這個計劃現在尚未結束，還在進行中。

In this thesis, we describe the Advanced Encryption Standard (AES) and the New European Schemes for Signatures, Integrity, and Encryption (NESSIE). In 1997, the National Institute of Standards and Technology (NIST) initiated a process to select a symmetric-key encryption algorithm. NIST selected MARS, RC6TM, Rijndael, Serpent and Twofish as finialists from 15 candidate algorithms. Finally the NIST decided to propose Rijndael as the AES. NESSIE is a Project within the Information Societies Technology (IST) Programme of the European Commission. NESSIE is a 3-year project, which started on 1st January 2000. The main objective of the NESSIE project is to put forward a portfolio of strong cryptographic primitives that has been obtained after an open call and been evaluated using a transparent and open process. These primitives include block ciphers, stream ciphers, hash functions, MAC algorithms, digital signature schemes, and public-key encryption schemes. NESSIE is still running and not yet finished now.
