This example uses the SE Manager API to perform the key agreement (ECDH) on the supported Series 2 device.
The Elliptic Curve Diffie-Hellman (ECDH) is an anonymous key agreement protocol that allows two parties, each having an elliptic curve public-private key pair, to establish a shared secret over an insecure channel.
In this example, two peers (client and server) each generate their Elliptic Curve Cryptography (ECC) key pair. They exchange public keys and compute a shared secret using their private ECC keys. These secrets are compared with each other to make sure they are equal.
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
).
