Module rsa

Available on crate feature unstable only.

RSA (Rivest–Shamir–Adleman) accelerator.

Overview

The RSA accelerator provides hardware support for high precision computation used in various RSA asymmetric cipher algorithms by significantly reducing their software complexity. Compared with RSA algorithms implemented solely in software, this hardware accelerator can speed up RSA algorithms significantly.

Configuration

The RSA accelerator also supports operands of different lengths, which provides more flexibility during the computation.

Examples

Modular Exponentiation, Modular Multiplication, and Multiplication

Visit the RSA test suite for an example of using the peripheral.

Modules

• operand_sizes
  Module defining marker types for various RSA operand sizes. Marker types for the operand sizes

Structs

• Rsa
  RSA peripheral container
• RsaModularExponentiation
  Support for RSA peripheral’s modular exponentiation feature that could be used to find the (base ^ exponent) mod modulus.
• RsaModularMultiplication
  Support for RSA peripheral’s modular multiplication feature that could be used to find the (operand a * operand b) mod modulus.
• RsaMultiplication
  Support for RSA peripheral’s large number multiplication feature that could be used to find the operand a * operand b.

Traits
