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 ...
The hash is then encrypted an AES-key, and used as authentication tag and AES-CTR initialization vector. 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 ...
NetLib Encryptionizer supports AES 128/256 in CBC, ECB and CTR modes for file and folder encryption on the Windows platform. Pidgin (software) , has a plugin that allows for AES Encryption Javascrypt [ 8 ] Free open-source text encryption tool runs entirely in web browser, send encrypted text over insecure e-mail or fax machine.
AES session cipher. 128 session encryption key size (bits) for cipher. GCM type of encryption (cipher-block dependency and additional options). SHA (SHA2)hash function. For a digest of 256 and higher. Signature mechanism. Indicates the message authentication algorithm which is used to authenticate a message. 256 Digest size (bits).
AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation. AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008. [2] A wider version of AES-NI, AVX-512 Vector AES instructions (VAES), is found in AVX-512. [3]
Advanced Encryption Standard (AES) with key sizes of 128 and 256 bits. For traffic flow, AES should be used with either the Counter Mode (CTR) for low bandwidth traffic or the Galois/Counter Mode (GCM) mode of operation for high bandwidth traffic (see Block cipher modes of operation) – symmetric encryption
For AES-128, the key can be recovered with a computational complexity of 2 126.1 using the biclique attack. For biclique attacks on AES-192 and AES-256, the computational complexities of 2 189.7 and 2 254.4 respectively apply. Related-key attacks can break AES-256 and AES-192 with complexities 2 99.5 and 2 176 in both time and data ...
A default cipher suite of GCM-AES-128 (Galois/Counter Mode of Advanced Encryption Standard cipher with 128-bit key) GCM-AES-256 using a 256 bit key was added to the standard 5 years later. Security tag inside each frame in addition to EtherType includes: association number within the channel
