This table shows the differences between the three types of cryptography text -- plaintext, cleartext and ciphertext. What are examples of plaintext? For most applications, plaintext is preferred. For example, a browser, word processor or email client should display plaintext. However, network p...
密码学Cryptography | 密码学(Cryptography)这一话题(向潜在敌人隐藏信息)已经存在了数千年。随着现代技术、计算机和电信的出现,它发生了巨大的变化。加密(encryption)是一种获取消息(称为明文 plaintext)并对其实施某个应用操作(称为密码或暗号 cipher)的行为。因此,在收到一条乱码、不可读的消息作为输出时,我们称为...
The art of protecting information by transforming it into an unreadable format, calledcipher text. Only those who possess a secret key can decipher (or decrypt ) the message intoplain text. Encrypted messages can sometimes be broken by cryptanalysis, also called codebreaking , although modern ...

This information is used to decrypt the rest of...
During encryption, an algorithm is used to scramble the content of the message and turn it into an unintelligible string of characters known as ciphertext. To unlock the ciphertext and turn it back into readable text, you need access to an encryption key. Encrypting a plaintext message helps...
An Introduction To Cryptography Plaintext-Based Attacks With a known plaintext attack, the attacker has knowledge of the plaintext and the corresponding ciphertext. This information is used to decrypt the rest of the ciphertext. With a chosen plaintext attack, the attacker can get a plaintext ...

1.1 Security Under Release of Unverified Plaintext AE security is typically examined using indistinguishability under chosen plain- text attack (IND-CPA) for privacy and integrity of ciphertexts (INT-CTXT) for integrity, and a scheme which achieves both is indistinguishable under chosen ciphertext ...
1. Communication and Data Transfer: Plaintext plays a crucial role in the seamless transfer of information between individuals or systems. When sensitive information needs to be transmitted securely, encryption techniques are applied to convert the plaintext into ciphertext. However, at the endpoints ...
Hill Cipher field of cryptography. HC is computationally attractive as using multiplication of a key matrix. HC has several advantages such as masquerading letter frequencies of the plaintext and high throughput [2‚ 3]. . Despite the ease and speed of the HC‚ the original HC is no lon...
