Cryptography symmetric key

WebThere are two main types of symmetric encryption: A. Block Encryption: In this, the set numbers of bits are ciphered in electronic data blocks with the help of a secret key. As the information is ciphered, the system stores … Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. The keys, in practice, represent a shared … See more Symmetric-key encryption can use either stream ciphers or block ciphers. • Stream ciphers encrypt the digits (typically bytes), or letters (in substitution ciphers) of a message one at a time. An example is See more Examples of popular symmetric-key algorithms include Twofish, Serpent, AES (Rijndael), Camellia, Salsa20, ChaCha20, Blowfish See more Many modern block ciphers are based on a construction proposed by Horst Feistel. Feistel's construction makes it possible to build invertible functions from other functions that are … See more Symmetric-key algorithms require both the sender and the recipient of a message to have the same secret key. All early cryptographic systems required either the sender or the recipient to somehow receive a copy of that secret key over a physically secure … See more Symmetric ciphers are commonly used to achieve other cryptographic primitives than just encryption. Encrypting a message does not guarantee that it will remain unchanged while encrypted. Hence, often a message authentication code is … See more Symmetric ciphers have historically been susceptible to known-plaintext attacks, chosen-plaintext attacks, differential cryptanalysis and linear cryptanalysis. Careful construction … See more When used with asymmetric ciphers for key transfer, pseudorandom key generators are nearly always used to generate the … See more
