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
).
The following key types are supported in this example:
The following key sizes are supported in this example:
The following payload sizes are supported in this example:
PLAIN_MSG_SIZE
/16PLAIN_MSG_SIZE
/4PLAIN_MSG_SIZE
The default PLAIN_MSG_SIZE
is 4096
, it is defined in app_se_manager_block_cipher.h
.
The following hash algorithms are supported in this example:
SHA-1
