RSA encryption algorithm developed by ZoTech is a ready-to-use application accelerated with AWS F1 (FPGA-based acceleration). In FPGA it performs the Montgomery modular exponentiation, the most computationally intensive portion of the algorithm. The application provides a modifiable reference design with a corresponding acceleration FPGA kernel. Fully designed under the SDAccel environment, the AMI demonstrates high performance signing, verification, encryption and decryption for RSA 2048 bit keys. Both reference design and OpenSSL integration source is available from https://github.com/ZoTechGroup/zt_rsa . For support, please contact support@zotechgroup.com .
