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. It is recommanded to use the Modular Exponentiation IP with processors that do not have a 32x32 multiplier.

The cryptographic functions performed by the RSA Software Library IP are RSA  ciphering, deciphering, signature verification and signature generation. The RSA Software Library benefits from the Chinese Remainder Theorem（CRT）for maximum efficiency. 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 SPARC V8 LEON2 MCU and  for the ARM CORTEX M3 MCU. It is delivered as a binary or in assembly source code. It is structured as independent API modules
