Key Features:
- Crypto element device with secure hardware-based key storage, 512 bit OTP (One Time Programmable) Bits for Fixed Information
- Based on the ATAES132A - a cryptographic coprocessor with secure hardware-based key storage from Microchip
- Used for storage of up to 16 keys, certificates, miscellaneous read/write, read-only or secret data, consumption logging, and security configurations
- mikroBUS: I2C and SPI Interface
The Secure 2 Click Board™ carries the ATAES132A, a cryptographic coprocessor with secure hardware-based key storage from Microchip. The Click Board™ is designed to run on either 3.3V or 5V power supply. The Secure 2 Click Board™ communicates with the target microcontroller over SPI and I2C interface, with additional functionality provided by the INT pin on the mikroBUS line.
Software Support
Code examples for the Secure 2 Click Board™, written for MikroElektronika hardware and compilers are available on Libstock.
CODE SNIPPET
The following code snippet shows functions that will lock the configuration zone of the device and then output a generated random number.
01 //Configuration zone locking
02 if (aes132m_execute(AES132_LOCK, 0x02, 0x0000, 0x0000,
03 0, 0, 0, 0, 0, 0, 0, 0, txBuffer, rxBuffer)
04 == AES132_FUNCTION_RETCODE_SUCCESS)
05 {
06 LOG( "rnrn Configuration zone locked! " );
07 }
08 else
09 {
10 LOG( "rnrn Configuration zone locking failed" );
11 LOG( " or it is already locked." );
12 }
13 memset (txBuffer, 0, 84);
14 memset (rxBuffer, 0, 36);
15 /*
16 Fourth test - Random number generator
17 Will only return 0xA5 unless config zone is locked first.
