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.

Modules

operand_sizes

Defines the exponentiation and multiplication lengths for RSA operations.

Structs

Rsa

RSA peripheral driver.

RsaBackend

RSA processing backend.

RsaContext

An RSA work queue user.

RsaHandle

The handle to the pending RSA operation.

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.

RsaWorkQueueDriver

An active work queue driver.

Traits

Multi

Defines the output type of RSA multiplications.

RsaMode

Defines the input size of an RSA operation.
