to encrypt a secret message
81Key generation — is the process of generating keys for cryptography. A key is used to encrypt and decrypt whatever data is being encrypted/decrypted.Modern cryptographic systems include symmetric key algorithms (such as DES and AES) and public key algorithms… …
82Integrated Encryption Scheme — (IES) is a hybrid encryption scheme which provides semantic security against an adversary who is allowed to use chosen plaintext and chosen ciphertext attacks. The security of the scheme is based on the Diffie–Hellman problem. Two incarnations of …
83Cocks IBE scheme — is an Identity based encryption system proposed by Clifford Cocks in 2001 [1]. The security of the scheme is based on the hardness of the quadratic residuosity problem. Contents 1 Protocol 1.1 Setup 1.2 Extract …
84Scytale — This article is about the encryption device; for the Dune character, see Scytale (Dune). In cryptography, a scytale (/sɪtəli/ rhymes with Italy, and also transliterated as skytale, Greek σκυτάλη , a baton) is a tool used to perform a… …
85Goldwasser-Micali cryptosystem — The Goldwasser Micali cryptosystem (GM) is an asymmetric key encryption algorithm developed by Shafi Goldwasser and Silvio Micali in 1982. GM has the distinction of being the first probabilistic public key encryption scheme which is provably… …
86NTLM — In a Windows network, NTLM (NT LAN Manager) is a suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users.[1][2][3] NTLM is the successor to the authentication protocol in Microsoft LAN Manager… …
87GPS signals — Global Positioning System (GPS) satellites broadcast radio signals to enable GPS receivers to determine location and synchronized time. Anatomy of a GPS signal GPS signals include ranging signals, used to measure the distance to the satellite,… …
88Block cipher — In cryptography, a block cipher is a symmetric key cipher operating on fixed length groups of bits, called blocks, with an unvarying transformation. A block cipher encryption algorithm might take (for example) a 128 bit block of plaintext as… …
89Post Office Protocol — In computing, local e mail clients use the Post Office Protocol version 3 (POP3), an application layer Internet standard protocol, to retrieve e mail from a remote server over a TCP/IP connection. POP3 and IMAP4 (Internet Message Access Protocol) …
90Anonymous remailer — An anonymous remailer is a server computer which receives messages with embedded instructions on where to send them next, and which forwards them without revealing where they originally came from. There are Cypherpunk anonymous remailers,… …
