I have read ETSI TS 103 097 and EEE Std 1609.2 which gives me the security data structure defined in ASN.1 notation. I want to use mbed LTS to calculate the ECDSA signature. I understand that I should calculate the ECDSA signature and then put the results in the data structure with the data and then encode it. my questions are:
- Can you please mention the steps of how to sign a CAM/DENM?
- Is there any example of how to use mbed LTS library to calculate ECDSA signature?
- where should I use the hashing algorithm?
