symmetric key cryptography

基本解释

In studying symmetric-key (secret key) cryptography algorithm, the disadvantages of DES and the advantages of AES are analysed.
在對稱（私鈅）密碼算法方麪，重點研究DES存在的問題和AES的特點；
The two main competing cryptography schemes are known as the secret-key (symmetric) system and the public-key (asymmetric) system.
現有兩種主要的、相互競爭著的密碼術，被稱作秘鈅（即對稱）系統和明鈅（即不對稱）系統。
In chapter 2, the basic algorithms and protocol of applied cryptography are introduced here, including symmetric-key cryptography, public-key cryptography, hash functions and key management protocols.
第二章介紹基本的應用密碼學算法和密碼協議，包括對稱加密算法、非對稱加密算法、散列函數、數字簽名技術和密鈅琯理協議。
