1.
Introduction to MbedTLS​

MbedTLS is a lightweight and flexible open-source cryptographic library designed for embedded systems. It provides essential security functionalities such as encryption, decryption, key generation, and data integrity verification. MbedTLS is particularly well-suited for microcontrollers and IoT devices due to its minimal footprint and modular design.​

2.
Supported Platforms​

MbedTLS supports the following MCU platforms:

•
YTM32B1HA0​

•
YTM32B1ME0​

•
YTM32B1MD1​

•
YTM32B1MC0​

3.
Supported Toolchains​

The provided implementations and examples are compatible with the following development toolchains:​

•
GCC​

•
IAR​

•
Keil​

4.
PSA-Based Example Implementations​

The following examples demonstrate cryptographic operations using the PSA (Platform Security Architecture) API within MbedTLS.​

1.
AES-128 Encryption and Decryption​

•
AES-128 ECB encryption and decryption.​

•
AES-128 CBC encryption and decryption.​

2.
RSA Key Generation and Hash Signing/Verification​

This example illustrates:

•
RSA key pair generation (private and public keys).​

•
Signing a message with RSA keys.​

•
Verifying the signature for message integrity.​

3.
ECC Key Generation and Hash Signing/Verification​

This example demonstrates:

•
ECC (Elliptic Curve Cryptography) key generation using PSA APIs.​

•
Signing a message with ECC keys.​

•
Verifying the generated signature for message integrity.​

5.
Configuration Supported by YT Config Tool​

Memory Allocation:

◦
 By default, MbedTLS uses the standard C library functions (malloc, calloc, realloc, and free) for dynamic memory allocation. However, in embedded systems or resource-constrained environments, you may want to use custom memory management functions to optimize memory usage or integrate with a specific memory allocator.​

◦
The memory management and allocation methods can be configured using YT Config Tool.​

General Configuration supported:

◦
Symmetric Encyption: AES​

◦
Asymmetric Encyption: RSA, ECC​

◦
Hash Algorithm and PKCS configuration​
