How to sign CAM/DENM messages using mbed LTS libray with ECDSA (EEE Std 1609.2)

in flag

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:

  1. Can you please mention the steps of how to sign a CAM/DENM?
  2. Is there any example of how to use mbed LTS library to calculate ECDSA signature?
  3. where should I use the hashing algorithm?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
