The following outline is provided as an overview of and topical guide to cryptography: Cryptography (or cryptology) – practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Applications of cryptography include ATM cards, computer passwords, and electronic ...

All algorithms support authenticated encryption with plaintext P and additional authenticated data A (that remains unencrypted). The encryption input also includes a public nonce N, the output - authentication tag T, size of the ciphertext C is the same as that of P. The decryption uses N, A, C, and T as inputs and produces either P or signals ...
Symmetric key cryptography—compute a ciphertext decodable with the same key used to encode (e.g., AES) Public-key cryptography—compute a ciphertext decodable with a different key used to encode (e.g., RSA) Digital signatures—confirm the author of a message; Mix network—pool communications from many users to anonymize what came from whom
This undoes step 4 of the encryption process. E n−1 = C n || Tail (D n, B−M). Pad C n with the extracted ciphertext in the tail end of D n (placed there in step 3 of the ECB encryption process). P n = Head (D n, M). Select the first M bits of D n to create P n. As described in step 3 of the ECB encryption process, the first M bits of D n ...
The internet has created some interesting and often baffling terms that are now part of our everyday lives. Not to mention all the abbreviations and acronyms that have popped up from texting and ...
Perform a "count cut": observe the value of the card at the bottom of the deck. If the card is either joker take its value to be 27 (53 when using a full deck). Remove that number of cards from the top of the deck and insert them just above the last card in the deck. 23 26 B 9 12 15 18 21 24 2 A 1 4 7 10 13 16 19 22 25 3 5 8 11 14 17 20 6
