Stronger security variants of gcm-siv
WebTherefore, variants of GCM have been proposed to achieve some more robust security notions. In 2015, Gueron et al. presented GCM-SIV [12] combining GCM’s underlying components with the SIV paradigm designed by Rogaway and Shrimpton [31], to provide nonce-misuse resistance. Later, at CRYPTO’17, Ashur et al. introduced WebJan 4, 2024 · GCM-SIV2 is a nonce-based beyond-birthday-bound (BBB)-secure authenticated encryption (AE) mode introduced by Iwata and Minematsu at FSE 2024. However, it is built by combining two instances of...

WebJul 12, 2024 · AES-GCM can target multiple security levels (128-bit, 192-bit, 256-bit), whereas ChaCha20-Poly1305 is only defined at the 256-bit security level. Nonce size: AES-GCM: Varies, but standard is 96 bits (12 bytes). If you supply a longer nonce, this gets hashed down to 16 bytes. WebStronger Security Variants of GCM-SIV.

WebBroadwell architecture. On Broadwell, GCM-SIV encryption takes only 0.92 cycles per byte, and GCM-SIV decryption is exactly the same as GCM decryption taking only 0.77 cycles per byte. In addition, we compare to other optimized authenticated-encryption implementations carried out by Bogdanov et al., and conclude that our mode is very competitive.
