Online training in English – Study of the security of PMR systems – How do basic privacy work?

In digital PMR radio networks (DMR, dPMR and NXDN), manufacturers offer different encryption methods to more or less effectively protect your exchanges from malicious eavesdropping.

There are generally 3 types of encryption:

  • Low level encryption (also-called “basic privacy”)
  • Intermediate encryption
  • Advanced (or high-level) encryption

What are these ciphers really worth? Do they offer real protection?

This is the kind of question that the online training/learning answers.

This is oriented towards « basic privacy » but it is a basis for understanding how more advanced encryption work.
