EN 50094:1992/A1:1995

Overview

EN 50094:1992/A1:1995 (EUROCRYPT) is a CLC-adopted access control standard for the MAC/packet family used in television and radio broadcasting. Published in national form as SIST EN 50094:1999/A1:1999, the document defines the EUROCRYPT conditional-access framework for secure distribution of broadcast services. The standard was originally handled by TC 206 and later transferred to the new TC 100X.

Key Topics

The standard focuses on access control and conditional-access mechanisms for the MAC/packet family (EUROCRYPT). Key technical topics and requirements addressed include:

• Scope and system architecture
  • Definition of the access control system role within broadcast distribution for MAC/packet environments.
• Security mechanisms
  • Requirements relating to encryption, authentication and protection of broadcast content (described at a system level).
• Packet/MAC-level interfaces
  • Specification of packet and MAC-family message handling required for conditional access interoperability.
• Key and entitlement management
  • High-level requirements for handling keys, entitlements and secure delivery of access control information.
• Interoperability and conformance
  • Requirements to ensure devices and conditional-access modules interoperate across vendor implementations.
• Operational considerations
  • Functional expectations for deployment, such as secure provisioning and revocation workflows.

Applications

EN 50094:1992/A1:1995 is directly relevant to professionals and organizations working in broadcast security and conditional access:

• Broadcasters and content distributors implementing conditional-access for subscription or pay-per-view services
• Conditional Access System (CAS) vendors and EUROCRYPT implementers
• Set-top box and CAM (conditional-access module) manufacturers targeting MAC/packet-based platforms
• System integrators and network operators deploying secure broadcast infrastructures
• Test laboratories and certification bodies conducting interoperability and compliance testing
• Regulators and standards bodies aligning national rules with European conditional-access practices

Related Standards

• Other CLC/CENELEC or ETSI standards for broadcasting and conditional access (refer to current TC assignments after transfer to TC 100X).
• Regional or industry conditional-access specifications for digital television may complement EN 50094 for implementation and testing.
