Information Flow Properties for Energy Management in a Smart Grid
Information flow security within the context of multilevel security deals with ways to avoid unwanted information flow from a high level domain to a low level domain. Several confidentiality and information flow properties have been formalized in literature. However, applying them to CyberPhysical Systems (CPSs) adds to the challenge of protecting confidentiality. This paper performs an informa...
متن کاملConfidentiality Levels and Deliberate/Indeliberate Protocol Attacks
A formal definition of confidentiality is developed using soft (rather than crisp) constraints. The goal is no longer considered as a mere yes/no property as in the existing literature, but gains an extra parameter, the security level. The higher the security level, the stronger the goal. For example, different messages may enjoy different levels of confidentiality, and the same message may enj...
متن کاملProtecting Micro-data by Micro-aggregation: the Experience in Eurostat
A natural strategy to protect the confidentiality of individual data is to aggregate them at the lowest possible level. Some studies realised in Eurostat on this topic will be presented: properties of classifications in clusters of fixed sizes, micro-aggregation as a generic method to protect the confidentiality of individual data, application to the Community Innovation Survey. The work perfor...
متن کاملSpecifying Confidentiality in Circus
This paper presents an approach for extending the Circus formalism to accommodate information flow security concerns. Working with the semantics of Circus, we introduce a notation for specifying which aspects of Circus processes are confidential and should not be revealed to low-level users. We also describe a novel procedure for verifying that a process satisfies its confidentiality properties.
متن کاملA Test for Non-Disclosure in Security Level Translations
Two security domains that want to exchange information securely may need to agree on translations of Mandatory Access Control (MAC) labels of their information, if their MAC labels have a different syntax or semantics. It is desirable that these translations do not introduce any confidentiality violations. In this paper we present a property, the Security Level Translation Property (SLTP), whic...
