The NanoSMP (Security Module Plugin) connector defines a provider interface layer for Secure Elements (SE) to integrate with NanoTAP (Trust Anchor Platform). The NanoTAP layer provides transport protocols and applications with a simple set of APIs to seamlessly integrate with any type of secure element. To build a connector with NanoSMP, the security module provider must register and implement the APIs based on the capabilities supported by the secure element.


> **Info**
>
> Each NanoSMP connector is a licensed extension of NanoTAP for a specific type of secure element (i.e., processor) and target operating environment (i.e., operating system).


NanoSMP is available in two models:

## Key features

The NanoSMP connector provides the following features, depending on the capabilities supported by the secure element:

- Small memory footprint
- Speeds integration and testing of complex cryptographic secure functions for your product
- Threadless, asynchronous architecture
- Guaranteed GPL-free code that protects your intellectual property
- API abstraction layer that provides APIs for the transport protocol stack and polyglot applications
- APIs for discovery, provisioning, context management, session management and secure functions.
- Extensible set of secure functions for cryptographic operations, random number generation, secure (measured, authenticated) storage, attestation, and key storage.

## System requirements

### Memory requirements

The NanoSMP connector for TPM 2.0/1.2 has a minimum memory footprint of 640KB.

Typical memory usage is with a full set of ciphers and may vary (decrease or increase) based on 32/64-bit, x86/ARM/MIPS, reduced set of ciphers, static/shared library, and compile flags.

### Supported operating systems

- Linux
- Microsoft® Windows
- FreeRTOS
- ThreadX

### Supported operating platforms

- Infineon® TPM 2.0/1.2 (Windows, Linux)
- ST-Micro® TPM 2.0/1.2 (Windows, Linux)
- Atmel® TPM 2.0/1.2 (Windows, Linux)
- NXP A71CH (FreeRTOS)
- Renesas S5 (ThreadX)
- PKCS#11-based SIM (Linux)
