加密货币的英文名称为“Cryptocurrency”。 如何拼写加密货币的英文名称? 加密货币的英文单词由两部分组成:crypto和currency。
加密货币(英文:Cryptocurrency,又译密码货币,密码学货币)是一种使用密码学原理来确保交易安全及控制交易单位创造的交易媒介。 加密货币是数字货币(或称虚拟货币)的一种 。比特币在2009年成为第一个去中心化的加密货币,这之后加密货币一词多指此类设计。 自此之后数种类似的加密货币被创造,它们通常被称作altcoins。 加密货币基于去中心化的共识机制 ,与依赖中心化监管体系的银行金融系统相对。
数据加密在15世纪中期开始使用,当时意大利科学家和发明家莱昂·巴蒂斯塔·阿尔贝蒂(Leon Battista Alberti)写了一篇关于创建密码的文章,可以用来保护个人和军事机密。阿尔贝蒂的密码从未被广泛使用,但它为现代密码学奠定了基础。
快进到20世纪,计算机的发展使更复杂的加密方法成为可能。这包括广泛使用的数据加密标准(DES),这是IBM在20世纪70年代开发的一种算法。1977年,美国国家标准与技术研究所(NIST)将DES标准化为联邦加密标准。然而,由于多年来计算能力的增长,DES在20世纪90年代被淘汰,取而代之的是高级加密标准(AES)。
AES使用对称密钥算法,这意味着使用相同的密钥对数据进行加密和解密。对称密钥算法快速而有效,但它们要求用户有一种安全的方式来交换密钥。这通常是通过使用公钥加密来实现的,比如流行的RSA加密。在公钥加密中,生成两个密钥——私钥和公钥。私钥是保密的,任何需要与密钥持有者交换信息的人都可以使用公钥。
数据加密现在用于许多日常活动,如网上银行、购物和云存储。它还用于保护互联网上计算机之间的通信,以及保护商业和政府机构的网络安全。加密还用于保护机密和敏感数据,如医疗记录和金融交易。
无论您需要保护哪种类型的数据,数据加密都是保证其安全的最佳方法。每天,组织都在使用加密来保护他们的数据免受黑客、身份窃贼和其他网络罪犯的攻击。通过使用先进的加密标准,组织可以保护他们的数据不被窥探,并确保只有授权用户才能访问他们需要的信息。
Data encryption began to be used in the mid-1400s when Italian scientist and inventor Leon Battista Alberti wrote about creating a cypher code that could be used to protect personal and military secrets. Alberti’s code was never widely used, but it served as a foundation for modern cryptography.
Fast forward to the twentieth century, when the development of computers allowed for much more sophisticated methods of cryptographic encryption. This includes the widely used Data Encryption Standard (DES), an algorithm developed by IBM in the 1970s. The National Institute of Standards and Technology (NIST) then standardized DES as a federal encryption standard in 1977. However, due to the growth of computing power over the years, DES was rendered obsolete in the 1990s and replaced by the Advanced Encryption Standard (AES).
AES uses a symmetric-key algorithm, which means that the same key is used to both encrypt and decrypt the data. Symmetric-key algorithms are fast and efficient, but they require the user to have a secure way to exchange the key. This is often done through the use of a public-key cryptography, such as the popular RSA encryption. In public-key cryptography, two keys are generated - a private key and a public key. The private key is kept secret, and the public key is available to anyone that needs to exchange information with the key holder.
Data encryption is now used for many everyday activities, such as online banking, shopping, and cloud storage. It’s also used to secure communications between computers over the Internet, as well as for securing networks in business and government organizations. Encryption is also used to protect classified and sensitive data, such as medical records and financial transactions.
No matter what type of data you need to protect, data encryption is the best way to keep it secure. Every day, organizations are using encryption to protect their data from hackers, identity thieves, and other cyber criminals. By using advanced encryption standards, organizations can protect their data from prying eyes and ensure that only authorized users can access the information they need.
