Hardware crypto engine is RFC7539-compliant
The new IP core, codename BA420, is available for ASIC and FPGA designs. With simple, straightforward interfaces, it is easy to integrate and highly scalable, hallmarks of all Silex Insight’s cores.
BA420 is used to verify the data integrity and the authenticity of messages or packets. It provides authenticated encryption with associated data (AEAD) using the Chacha20 stream cipher combined with the Poly1305 message authentication code (MAC). Its maximum throughput exceeds several hundreds of Gbps and it can be fully configured to match the specific throughput requirements of the application and hardware platform. For SoC solutions, the core can be combined with optional scatter/gather DMA for easy and efficient integration. Alternatively, BA420 can also be deployed for encryption or authentication separately.
The BA420 block may be combined with the BA415, which implements a high-throughput AES-GCM crypto engine. This combination offers future-proof security, as Chacha20-Poly1305 is a mandatory AEAD (authenticated encryption with associated data) algorithm, as is the AES-GCM, in TLS 1.3. It’s also a more secure alternative to older algorithms in TLS/SSL, the underlying protocol that secures most Internet communication in browsers.
