Part 2 : symmetric cryptography 第2部分:對(duì)稱密碼術(shù)
In symmetric cryptography systems , a single key that is used for both encryption and decryption 在對(duì)稱密碼術(shù)系統(tǒng)中同時(shí)用于加密和解密的單個(gè)密鑰。
Public key cryptography is also known as asymmetric cryptography , which is different from symmetric cryptography described in last month s column 公鑰密碼術(shù)也稱為非對(duì)稱密碼術(shù),它不同于在上個(gè)月的專欄文章中所講的對(duì)稱密碼術(shù)。
Provides an introduction to key concepts in cryptography , such as asymmetric cryptography , symmetric cryptography , digital signatures , and cryptographic hashes 介紹加密的主要概念,例如不對(duì)稱加密、對(duì)稱加密、數(shù)字簽名和加密哈希。
