The RSA Software Library IP is a library of embedded software optimized for maximum throughput and minimum memory utilization. The RSA Software Library IP include high-end software counter-measures against side-channel attacks and fault-injection attacks.
The RSA Software Library IP can run in stand-alone mode and can also run in conjunction with INVIA's Modular Exponentiation IP that provides hardware acceleration of cryptographic calculations.
The cryptographic functions performed by the RSA Software Library IP are RSA encryption, decryption, signature verification and signature generation. The RSA calculations can be performed with or without the CRT (Chinese Remainder Theorem). Note that the countermeasures against fault-injection are very efficient even when the CRT is used during calculation.
The RSA Software Library is performance-optimized for the ARM Cortex-M3 MCU. It is delivered as a binary or in assembly source code. It is structured as independent API modules
