General

ISO/IEC ISP 10613 is applicable to interworking units concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI standards that collectively provide a Network Relay function for the connection-mode Network Service.

Part 7 of ISO/IEC ISP 10613 specifies subnetwork type dependent requirements for an interworking unit when attached to an X.25 packet switched data network by a dedicated (permanent) access line and using virtual calls.

This part of ISO/IEC ISP 10613 specifies the profile requirements for the provision of security services using cryptographic techniques with Network Layer Security Protocol connection-mode and SDT-PDU based protection for use with X.25 packet switched data networks as specified in part 7 of 10613.

Position within the Taxonomy

The taxonomy of profiles is specified in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 106 13 supports security services for RA1111 and RA1121 profiles as specified in ISO/IEC ISP 10613 part 5.

Scenario

Relay System

Security Services

The following security services are within the scope of this profile:

• Peer entity authentication
• Connection integrity without recovery (including replay protection)
• Access control using security labels
• Connection confidentiality (optional)
• Traffic flow confidentiality (optional)

Security Mechanisms

This part of ISO/IEC ISP 10613 provides no assurance as to the strength of the security mechanisms employed.

This part of ISO/IEC ISP 10613 does not specify the cryptographic algorithms to be employed.
