dc.description.abstractTerrestrial Trunked Radio (TETRA) is a new digital standard for Private Mobile Radio (PMR) systems. With emphasis on security during standardization, TETRA is regarded as a highly secure system and suitable for use by Public Safety & Security (PSS) organizations that require a high degree of security in their communication environments. The Norwegian PSS organizations currently use communication systems and equipment that is not interoperable, lack functionality, and provides little or no security. A project has therefore been initiated to examine the possibilities of implementing a nation-wide mobile communication network for all the PSS organizations. The TETRA system is identified as the most promising technology to base a new network on. This thesis takes a look at how the security architecture in TETRA would fulfill security requirements for a Norwegian PSS communication network. This has been narrowed down to the following statements: · Provide a summary of security in mobile communication systems. · Define security requirements for a Norwegian PSS communication network. · Provide an overview of the TETRA standard. · Describe the security architecture as defined by the TETRA standard, including possible end-to-end solutions for enhanced security. · Perform an analysis of TETRA security in relation to the identified security requirements. The TETRA system provides a wide range of communication services and the migration between public cellular services and traditional PMR services is evident. The TETRA security architecture is also quite extensive, but only air interface security is fully specified. Two approaches for adding end-to-end security to TETRA have therefore been examined, one based upon a framework presented by the TETRA Security and Fraud Prevention Group (SFPG) and one based upon using an external device in the form of an appliqué. An analysis of the TETRA security architecture in relation to the identified requirements for a Norwegian PSS communication network shows that the lack of standardized end-to-end security in TETRA can make the PSS communication system insecure. A higher grade of protective measures than what can be provided with only TETRA air interface security is needed. The use of additional end-to-end security services is therefore necessary in a Norwegian PSS communication network. It is not recommended that TETRA in its current state is used to implement a new PSS communication network in Norway. It is suggested that a more secure solution will be available when the TETRA technology has matured for a few years and the enhancements in the security architecture provided by TETRA Release 2 become available.nor
