With the consideration of system throughput and system security requirement, the proposed game theoretical approach enables the system to strategically select its relay by dynamically updating its belief in the maliciousness of relays according to its record of attacks.
Therefore, with the satisfaction of the system security requirement, the source would not necessarily authenticate all packets, according to the possibility that packets forwarded by the selected relay are not compromised by the attacker because the source's relay selection is different from the attacker's attacking target selection.
In our model, the system security requirement is defined as the maximum percentage of packets forwarded to the destination through the selected relay that are compromised by the attacker if the attacker's attacking target selection coincides with the source's relay selection.
Denote the probability of message authentication as p a. To satisfy system security requirement p s, we have 0 ≤ ( 1 - p a ) · p i ∗ ≤ p s by selecting relay R i as relay with probability p i ∗ being attacked by the attacker.
Irrespective of the system and security requirements, a watermarking scheme can have three fundamental components as mentioned in section 1 and shown in Figure 1.
Jay Kaplan, co-founder of the cybersecurity firm Synack, notes a bright spot: The Election Assistance Commission has a national voting system certification program to independently verify that a voting system meets security requirements.
The Sites@Duke team reviews feature requests on a rolling basis to assess compatibility with system and security requirements.
Compared to transmission system, distribution system has lower security requirements and cares about only static security instead of transient security.
SungardAS BrandVoice: Can Managed IT Services Give Your IT System A Boost? Can Managed IT Services Give Your IT System A Boost? Security requirements are changing every day as cyber threats get more and more sophisticated.
Therefore, the application of liveness detection methods is a very important task and should be implemented (not only) in all systems with higher security requirements, such as border passport control systems and bank systems.
