  2. Galois/Counter Mode - Wikipedia

    en.wikipedia.org/wiki/Galois/Counter_Mode

    Impressive performance results are published for GCM on a number of platforms. Käsper and Schwabe described a "Faster and Timing-Attack Resistant AES-GCM" [15] that achieves 10.68 cycles per byte AES-GCM authenticated encryption on 64-bit Intel processors. Dai et al. report 3.5 cycles per byte for the same algorithm when using Intel's AES-NI ...

  3. Authenticated encryption - Wikipedia

    en.wikipedia.org/wiki/Authenticated_encryption

    Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key [1]) and authenticity (in other words, it is unforgeable: [2] the encrypted message includes an authentication tag that the sender can calculate only while possessing the ...

    en.wikipedia.org/wiki/ChaCha20-Poly1305

    ChaCha20-Poly1305 is an authenticated encryption with associated data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. [1] It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM. [1]: §B

  5. Block cipher mode of operation - Wikipedia

    en.wikipedia.org/wiki/Block_cipher_mode_of_operation

    AES-GCM-SIV is an improvement over the very similarly named algorithm GCM-SIV, with a few very small changes (e.g. how AES-CTR is initialized), but which yields practical benefits to its security "This addition allows for encrypting up to 2 50 messages with the same key, compared to the significant limitation of only 2 32 messages that were ...

  6. EAX mode - Wikipedia

    en.wikipedia.org/wiki/EAX_mode

    EAX mode (encrypt-then-authenticate-then-translate [1]) is a mode of operation for cryptographic block ciphers. It is an Authenticated Encryption with Associated Data algorithm designed to simultaneously provide both authentication and privacy of the message (authenticated encryption) with a two-pass scheme, one pass for achieving privacy and one for authenticity for each block.

  7. Poly1305 - Wikipedia

    en.wikipedia.org/wiki/Poly1305

    Poly1305 is a universal hash family designed by Daniel J. Bernstein in 2002 for use in cryptography. [1] [2]As with any universal hash family, Poly1305 can be used as a one-time message authentication code to authenticate a single message using a secret key shared between sender and recipient, [3] similar to the way that a one-time pad can be used to conceal the content of a single message ...

  9. CWC mode - Wikipedia

    en.wikipedia.org/wiki/CWC_mode

    In cryptography, CWC Mode (Carter–Wegman + CTR mode) is an AEAD block cipher mode of operation that provides both encryption and built-in message integrity, similar to CCM and OCB modes. It combines the use of CTR mode with a 128-bit block cipher for encryption with an efficient polynomial Carter–Wegman MAC with a tag length of at most 128 ...
