Techniques for Integrity Mechanisms in IBC

Objective

The broad objectives of this project were concerned with making transmitted data secure and proving their integrity. This meant devising legally binding procedures for the execution of data exchange transactions.
Research has been carried out with respect to making transmitted data secure. This involved devising legally binding procedures for the execution of data exchange transactions.

These procedures enable the user and the terminal in question to be identified, to test access authorization and to prevent the falsification of data. Once defined, these procedures can also be used to safeguard the transmission of control data of the integrated broadcast communications (IBC) operator.

The research addressed some specific objectives involving the development of possible integrity concepts in IBC services, cost and performance and definition of a feasible global integrity system, taking into consideration in particular: peer entity authentication, digital signature, anonymity, proof of origin and receipt, access control, data integrity, integrity management.

As result of the theoretical work carried out 9 deliverables have been finalized. A security threat model for the IBC was outlined, descriptions of integrity mechanism and required formalisms presented and references made to related standardization activities. Results of the integrity mechanisms investigation, evaluation and classification together with the study of the relevant characteristics for solutions for integrity services were documented.
A set of conclusions related to integrity policy and integrity management were elaborated upon and a global integrity system aiming at providing guidelines for the IBC was proposed in order to support integrity services for every application available.
Technical Summary

These procedures must enable the user and the terminal in question to be identified, to test access authorisation and to prevent the falsification of data. They must be so clearly defined and secure that the scope of these procedures cannot be contested. Once defined, these procedures can also be used to safeguard the transmission of control data of the IBC operator.

During 2 years, this project has been able to address some specific objectives:

- development of possible integrity concepts in IBC services
- cost and performance
- definition of a feasible global integrity system, taking into consideration in particular: peer entity authentication, digital signature, anonymity, proof of origin and receipt, access control, data integrity, integrity management.

Nine deliverables have been finalised as result of the theoretical work carried out. Deliverable 1 and 2 are devoted to the determination of the IBC integrity needs and research for integrity mechanisms. Deliverable 7 expands this last item. A security threat model for the IBC was outlined, descriptions of integrity mechanism and required formalisms presented and references made to related standardisation activities. Results of the integrity mechanisms investigation, evaluation and classification together with the study of the relevant characteristics for solutions for integrity services are documented in deliverables 3, 4, 5 and 6.

The project elaborated a set of conclusions related to integrity policy (deliverable 6) and integrity management (deliverable 9) and proposed a global integrity system aiming at providing guidelines for the IBC in order to support integrity services for every application available (deliverable 10).
