Conditional access systems

Conditional Access Systems (CAS) are security mechanisms used by broadcasters and service providers to control and restrict access to digital content like TV channels and streaming services. They verify user permissions based on subscription details or decryption keys, ensuring only authorized viewers can access the content. Essentially, CAS prevents unauthorized sharing or piracy by encrypting the content and only allowing it to be decrypted and viewed by subscribers with valid credentials. This system helps content providers protect their intellectual property while offering personalized access to legitimate users.
