How was the authorization scheme implemented in the two-way system?

In a two-way system, authentication is usually implemented through mutual authentication of both parties — the client and the server. A common scheme involves the exchange of tokens or certificates, where each party confirms its identity.

For example, in API systems, OAuth 2.0 with JWT tokens may be used, where the client receives a token and the server verifies it with each request. In more complex cases, mutual TLS authentication is used, where both the client and the server present certificates to confirm their identities.

Thus, the scheme is based on:

• Identification of both parties
• Access rights verification
• Ensuring data transmission security

This guarantees that both parties trust each other and have the necessary rights for interaction.
