WebMar 20, 2024 · Keyword cipher is a form of monoalphabetic substitution.A keyword is used as the key, and it determines the letter matchings of the cipher alphabet to the plain alphabet. Repeats of letters in the word are removed, then the cipher alphabet is generated with the keyword matching to A, B, C, etc. until the keyword is used up, whereupon the … WebApr 17, 2024 · Wonderful explanations. It is key to know that IV1, IV2 can be obtained fairly easily in TLS 1.0, but this is made impossible in TLS 1.1 and 1.2. Without knowing two IVs, CBC attack can not be done. Note that CBC padding oracles are also possible for TLS because it uses mac-then-encrypt instead of encrypt-then-mac.

The IV is typically required to be random or pseudorandom, but sometimes an IV only needs to be unpredictable or unique. Randomization is crucial for some … See more A block cipher is one of the most basic primitives in cryptography, and frequently used for data encryption. However, by itself, it can only be used to encode a data block of a predefined size, called the block size. … See more In stream ciphers, IVs are loaded into the keyed internal secret state of the cipher, after which a number of cipher rounds are executed prior to releasing the first bit of output. For … See more In cipher-block chaining mode (CBC mode), the IV need not be secret, but must be unpredictable (In particular, for any given plaintext, it must not be possible to predict the IV that will be … See more Properties of an IV depend on the cryptographic scheme used. A basic requirement is uniqueness, which means that no IV may be … See more Block cipher processing of data is usually described as a mode of operation. Modes are primarily defined for encryption as well as See more The 802.11 encryption algorithm called WEP (short for Wired Equivalent Privacy) used a short, 24-bit IV, leading to reused IVs with the same key, which led to it being easily cracked.
