Bus protection and encryption

BA432 IP core for bus protection

Overview

The BA432a and BA432b IP cores are developed validated and licensed by Silex Insight.

The BA432a is an in-line decryption IP Core enabling on- the-fly execution of encrypted code from Flash. The BA432b is an in-line bus protection module that implements data privacy and authentication. It is typically placed between the processor(s) and an external memory controller (DDRx).

Features

• On-the-fly encrytion/decryption and authentication
• In-place execution of encrypted code
• Transparent for the processor
• Scalable data bus width (32, 64, 128 bits)
• Based on AES fully compliant with NIST FIPS 197
• Supports all key sizes (128/192/256 bits)
• Scalable internal Cache
• ASIC/FPGA SoC
• AHB/AXI Master/slave interfaces
• SPA/DPA countermeasures (optional)
• Easy to integrate
• Can be provided with Q-SPI Controller (optional)

Applications

• On-the-fly execution of encrypted code
• Embedded security processor
• Finance and payment
