State Machine-Based Security Fusion for Resource-Constrained Environments

Policy-Controlled Authenticated Access to LLN-Connected Healthcare Resources

“…Other schemes focus on efficiently providing authenticated encryption, like the Identity-based Cryptosystem (IBC) signcryption mechanisms presented by Fagen et al [42]. Related to the above is the relatively novel concept of security fusion, whereby weak point-to-point properties are combined in order to produce strong security properties in a resource-aware manner [43].…”

Security fusion based on state machine compositions

“…Security fusion [20] is a novel framework in security for inherently resource-limited systems. Unlike traditional cryptographic schemes, the general approach here is to introduce lightweight primitives at the individual nodes that provide a strong aggregation to security properties at the systemlevel.…”

“…Our earlier paper [20] introduces the concept of security fusion with a detailed description on a state machine-based architecture to realizing the framework. In this architecture, the basic idea is to have a challenge-response system that extracts a global security property from the response pattern of all the nodes.…”

“…In this architecture, the basic idea is to have a challenge-response system that extracts a global security property from the response pattern of all the nodes. In [20], we analyzed the security characteristics of the proposed scheme and showed how it withstands a wide variety of attacks including cloning and intrusion.…”

“…

Security fusion is a new paradigm in security for resource-constrained environments [20]. Following this paradigm, strong system-level security is achieved by combining weak primitives from multiple nodes.
