  2. Key generation - Wikipedia

    en.wikipedia.org/wiki/Key_generation

    A sender encrypts data with the receiver's public key; only the holder of the private key can decrypt this data. Since public-key algorithms tend to be much slower than symmetric-key algorithms, modern systems such as TLS and SSH use a combination of the two: one party receives the other's public key, and encrypts a small piece of data (either ...

  3. Key generator - Wikipedia

    en.wikipedia.org/wiki/Key_generator

    A key generator [1] [2] [3] is a protocol or algorithm that is used in many cryptographic protocols to generate a sequence with many pseudo-random characteristics. This sequence is used as an encryption key at one end of communication, and as a decryption key at the other.

  4. Traitor tracing - Wikipedia

    en.wikipedia.org/wiki/Traitor_tracing

    If the key is made public, the content owner then knows exactly who did it from their database of assigned codes. A major attack on this strategy is the key generator ( keygen ). By reverse engineering the software, the code used to recognise a valid key can be characterised and then a program to spit out valid keys on command can be made.

  5. Camellia (cipher) - Wikipedia

    en.wikipedia.org/wiki/Camellia_(cipher)

    In cryptography, Camellia is a symmetric key block cipher with a block size of 128 bits and key sizes of 128, 192 and 256 bits. It was jointly developed by Mitsubishi Electric and NTT of Japan . The cipher has been approved for use by the ISO/IEC , the European Union 's NESSIE project and the Japanese CRYPTREC project.

  6. RSA Secret-Key Challenge - Wikipedia

    en.wikipedia.org/wiki/RSA_Secret-Key_Challenge

    The RSA Secret-Key Challenge was a series of cryptographic contests organised by RSA Laboratories with the intent of helping to demonstrate the relative security of different encryption algorithms. The challenge ran from 28 January 1997 until May 2007.

  7. NTRUEncrypt - Wikipedia

    en.wikipedia.org/wiki/NTRUEncrypt

    The NTRUEncrypt public key cryptosystem, also known as the NTRU encryption algorithm, is an NTRU lattice-based alternative to RSA and elliptic curve cryptography (ECC) and is based on the shortest vector problem in a lattice (which is not known to be breakable using quantum computers).

  8. ChaCha20-Poly1305 - Wikipedia

    en.wikipedia.org/wiki/ChaCha20-Poly1305

    The two building blocks of the construction, the algorithms Poly1305 and ChaCha20, were both independently designed, in 2005 and 2008, by Daniel J. Bernstein. [2] [3]In March 2013, a proposal was made to the IETF TLS working group to include Salsa20, a winner of the eSTREAM competition [4] to replace the aging RC4-based ciphersuites.

  9. Server-Gated Cryptography - Wikipedia

    en.wikipedia.org/wiki/Server-Gated_Cryptography

    SGC became obsolete when Internet Explorer 5.01 SP1 and Internet Explorer 5.5 started supporting strong encryption without the need for a separate high encryption pack (except on Windows 2000, which needs its own high encryption pack that was included in Service Pack 2 and later). [3] "Export-grade" browsers are unusable on the modern Web due ...
