Public Key Accelerator (PKA): ECC/RSA ALU PKA
Public key cryptography requires complex mathematical operations on very large numbers (from 160 to 4096 bits, or more). The majority of embedded CPUs are limited to operations on 32- and 64-bit values and require significant computational resources when implementing public key infrastructure related algorithms. The DesignWare® Public Key Accelerator (PKA) is dedicated to the computationally intensive elements of the mathematics required for RSA operations as well as the algorithms used in prime field elliptic curve cryptography (ECC). The PKA integrates seamlessly with the DesignWare cryptography software library, enabling designers to accelerate the asymmetric cryptography required in public key algorithms, to deliver performance levels that are not achievable in software-only solutions.

Video Demo of the Public Key Accelerator (PKA): ECC/RSA ALU PKA
See how designers can provision any IoT device using Truphone’s integrated SIM solution and DesignWare tRoot Fx HSMs. This demo shows the Truphone eSIM running an ARC EM Starter Kit board integrated with a commercial mobile device. It demonstrates the main use-cases of GSMA Remote SIM provisioning for IoT and consumer devices. Using Truphone bootstrap connectivity, the demo shows how in-the-field remote device activation is possible for any mobile operator and can completely remove the logistics and costs associated with physical SIM cards.
