SE Manager Block Cipher

This example uses the SE Manager API to perform the block ciphers on the supported Series 2 device.

The example redirects standard I/O to the virtual serial port (VCOM) of the kit. By default, the serial port setting is 115200 bps and 8-N-1 configuration.

The example has been instrumented with code to count the number of clock cycles spent in different operations. The results are printed on the VCOM serial port console. This feature can be disabled by defining SE_MANAGER_PRINT=0 (default is 1) in the IDE setting (Preprocessor->Defined symbols).

Key Type

The following key types are supported in this example:

Key Size

The following key sizes are supported in this example:

Payload Size

The following payload sizes are supported in this example:

The default PLAIN_MSG_SIZE is 4096, it is defined in app_se_manager_block_cipher.h.

Hash Algorithm (HMAC)

The following hash algorithms are supported in this example:

Cipher Algorithm

The following cipher algorithms are supported in this example:

The ChaCha20-Poly1305 can only use a 256-bit key.

SE Manager API

The following SE Manager APIs are used in this example:

Getting Started

  1. Upgrade the kit’s firmware to the latest version (see Adapter Firmware under General Device Information in Simplicity Studio 5 Users Guide).
  2. Upgrade the device’s SE firmware to the latest version (see Secure Firmware under General Device Information in Simplicity Studio 5 Users Guide).
  3. Open any terminal program and connect to the kit’s VCOM port (if using Device Console in Simplicity Studio 5, Line terminator: must be set to None).
  4. Create this platform example project in the Simplicity IDE (see Examples in Simplicity Studio 5 Users Guide, check Platform() checkbox to browse the platform examples).
  5. Build the example and download it to the kit (see Simple Build and Flash Programmer in Simplicity Studio 5 Users Guide).
  6. Run the example and follow the instructions shown on the console.

Additional Information

  1. The default optimization level is Optimize for debugging (-Og) on Simplicity IDE and None on IAR Embedded Workbench.
