The AES-XTS encryption IP core implements encryption/decryption for sector-based storage data. It uses the AES block cypher, in compliance with the NIST Advanced Encryption Standard, as a subroutine. The core processes 128 bits per cycle, and is programmable for 128- and 256-bit key lengths.
Two architectural versions are available to suit system size and throughput requirements. The XTS-X is more compact and can process 128 bits/cycle independent of the key size. The XTS-X2 can process 256 bits/cycle independent of the key size. Both versions have a 128-bit data path.
AES-XTS Encryption and Decryption, compliant to to IEEE P1619™/D16 standard
High throughput: 128 bits/cycle (AES-XTS-X version) or 256 bits/cycle (AES-XTS-X2 version). From 20 to 40Gbps on Arria10 devices.
User-programmable key size of 128 or 256 bits and initialization vector of arbitrary length
Complete deliverables include test benches, C model and test vector generator
Device Utilization and Performance
The AES-XTS can be mapped to any Intel FPGA device (provided sufficient silicon resources are available). The core has two versions:
a)\tThe AEX-XTS-X can process 128 bits/sample, occupies 4,900 ALMs and 1.8M RAM bits, and provides throughput of ~20Gbps on an Arria10 device.
b)\tThe AEX-XTS-X2 can process 256 bits/sample, occupies 8,500 ALMs and 3.5M RAM bits, and provides throughput of ~40Gbps on an Arria10 device.
