Keystream not linearly related to key 相关知识点: 试题来源: 解析 B 正确答案:B解析:B正确。对称算法的两个主要类型是分组密码和流密码。分组密码以分组为单位执行数学函数运算,而流密码并不对消息进行分组。相反,流密码把消息当做位流,并单独对每一个位执行数学函数运算。好的流密码具有下列特征:不可预见的...
While both DES and AES use symmetric block ciphers, AES uses a substitution-permutation network wherein plaintext goes through multiple rounds of substitution (S-box) and permutation (P-box) before finalizing the ciphertext block. Similarly, a client or application can decrypt the AES message by...
self-synchronizing stream cipherThis chapter explains two basic types of symmetric algorithms: block ciphers and stream ciphers. A cryptographic mode usually combines the basic cipher, some sort of feedback, and some simple operations. The operations are simple because the security is a function of ...

Stream Cipher− Stream ciphers transform data one bit (or one byte) at a time instead of operating on a block basis. Simply say, a stream cipher uses a given key to generate a keystream. The plaintext data is then XORed with the generated keystream. ...

Cryptography is the process of hiding or coding information so only the intended recipient can read a message. Discover how cryptography works and the potential risks it poses.
While it has great security, the OTP is rarely used because it is impractical to securely share the massive amounts of key material that it needs to work. A stream cipher uses the same idea as the OTP with a slightly less secure key. ...
