Advanced Encryption Standard Core

AES: Advanced Encryption Standard Core

GENERAL DESCRIPTION

LancsNet AES fully supports NIST FIP-197 standards and is a bandwidth-resource scalable AES engine. Our implementation permits pipeline stages can be configured by end-users to achieve the desired bandwidth ranging from 2-16Gbps. The core is ready to be adopted for popular NIST cipher modes such as ECB, CBC, OFB, CFB, CTR. AES currently is adopted as the major encryption/decryption workhorse in many protocols and applications (AES-GCM, ESP, TLS).
