Our EFM32™ Giant Gecko Series 1 ARM® Cortex®-M4-based 32-bit microcontrollers (MCUs) are the most integrated and high performance low power MCUs available and include robust security via a unique cryptographic hardware engine supporting AES, ECC, SHA, and True Random Number Generator (TRNG).

Sha-512 is a function of cryptographic algorithm Sha-2, which is an evolution of famous Sha-1. Sha-512 is very close to its "brother" Sha-256 except that it used 1024 bits "blocks", and accept as input a 2^128 bits maximum length string. Sha-512 also has others algorithmic modifications in comparison with Sha-256. AES allows encryption keys up to 256 bits. Certain Ketu products allow 512 bits, using double AES. NOTE: The KetuFile programs accept keys that comprise uppercase and lower case letters and numbers. This results in an approximately 4-fold reduction of key states. Therefore a so-called KetuFile 256 bit key has approximately 2^252 states. Modern encrypted SSDs use a 128- or 256-bit AES algorithm along with two symmetric encryption keys (Fig. 1). The first key is the Encryption Key, used to encrypt all data stored on the drive. AES has the ability to deal with three different key sizes such as AES 128, 192 and 256 bit and each of this ciphers has 128 bit block size. Using 512 . Bit Key from malicious attacks

Dec 02, 2015 · AES is a new generation cipher that supports key lengths a minimum of 128 and a maximum of 256 bits, each with a fixed block size of 128 bits. This encryption algorithm is secure enough for all modern needs. AES 128 bits vs AES 256 bits. Both 128-bit and 256-bit encryptions are of the military level. Both are considered to be invulnerable to

As a result, users wanting AES -256 and AES-128 encryption must supply 512 bits and 256 bits of key respectively. On January 27, 2010, NIST released Special Publication (SP) 800-38E in final form. SP 800-38E is a recommendation for the XTS-AES mode of operation, as standardized by IEEE Std 1619-2007, for cryptographic modules.

AES comes with three standard key sizes (128, 192 and 256 bits). Many people see this and think that if there are three distinct sizes instead of just one, then there must be some difference, and since the 256-bit version is a bit slower than the 128-bit version (by about 40%), it must be "more secure". So they go for "the most secure" and

2 stage cascade AES 256-bit equals to 512-bit encryption Conforms to HIPAA regulation regarding patient privacy and to Sarbanes-Oxley regarding corporate financial and accounting practice CipherShield Smart Insert technology with Cipherkey to authenticate the drive FDE (Full Disk Encryption) encrypt whole drive Dec 08, 2011 · The new algorithm (AES-512) uses input block size and key size of 512-bits which makes it more resistant to cryptanalysis with tolerated area increase. AES-512 will be suitable for applications with high security and throughput requirements and with less chip area constrains such as multimedia and satellite communication systems. Until there is a major step-change is computing technology, 512-bit encryption belongs in the ‘style over substance’ category. 256-bit encryption is sufficient to protect against sustained attacks from very sophisticated criminal gangs or the resources associated with rogue state entities.
