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 ...
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
GCM was designed by John Viega and David A. McGrew to be an improvement to Carter–Wegman counter mode (CWC mode). [4] In November 2007, NIST announced the release of NIST Special Publication 800-38D Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM) and GMAC making GCM and GMAC official standards. [5]
AES-GCM-SIV is a mode of operation for the Advanced Encryption Standard which provides similar (but slightly worse [1]) performance to Galois/Counter Mode as well as misuse resistance in the event of the reuse of a cryptographic nonce. The construction is defined in RFC 8452.
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 ...

The 20-year-old blind cat from New England was rescued by Good Samaritans after floating on a piece of ice on a Massachusetts lake and falling in on Dec. 16, 2024.
Abyssinian cats are high-energy beauties that are believed to be one of the oldest cat breeds ever. They are thought to be excellent at swimming too. If you need to give a cat a bath, you'd better ...
