If the overall trust is based on just the communication trust, it might mislead the network, that is; untrustworthy nodes in terms of sensed data can be classified as trusted nodes due to their communication capabilities.
Moreover, we propose a novel node evaluation solution with the assistance of trustworthy neighboring nodes, which allows a mobile node to more effectively evaluate its neighbors based on the additional trust information from selected neighboring nodes.
By combining these two components in the trust model, we can obtain more accurate trust values of the observed nodes in MANETs.
Simulation results show that the proposed mechanism improves significantly the performance of underlying network, providing a sufficient correct knowledge about nodes trustworthiness required by trust management frameworks.

Where network security key on router?4 answersThe network security key on a router is typically stored and managed within the router itself. One approach is to use a number lock system embedded on the router, where the user can enter a shared key or seed using a combination of numbers and letters on the dials of the number lock. Another method involves the use of cryptographic keys, where the router generates a routing private key and a routing public key, and devices connected to the router generate their own device public and private keys. The router then uses these keys to encrypt and decrypt data as it is transmitted between devices and the external network. Additionally, routers play a crucial role in network security management, providing functions such as packet filtering, authentication, access control, intrusion analysis, and audit trail, which help protect against network attacks and ensure secure networking.
Why authenticated or encrypted communications important in sensor networks?5 answersAuthenticated and encrypted communications are important in sensor networks due to several reasons. Firstly, sensor networks often collect and transmit sensitive data in real-time, such as in smart cities, medicine, and military applications. Without authentication, an adversary can intercept the network and steal valuable information, compromising privacy and security. Encryption ensures that the data cannot be understood by unauthorized parties, providing confidentiality. Secondly, authentication mechanisms in sensor networks help ensure that the messages received are from legitimate sensor nodes and have not been modified during transmission. This prevents unauthorized and undisrupted communication, protecting the integrity of the network. Additionally, authentication helps prevent various security threats such as password-guessing, identity-guessing, and user-impersonation. Overall, authenticated and encrypted communications are crucial for maintaining the privacy, integrity, and security of data in sensor networks.
How is decentralised authentication evaluated?4 answersDecentralized authentication is evaluated by considering various metrics such as time, CPU, and memory.

What are the different methods of certificate verification?5 answersThere are several methods of certificate verification mentioned in the abstracts. One approach involves detecting labels in the image and extracting corresponding fields to be verified from the original image as multiple cropped images. The text in these cropped images is recognized using the EasyOCR module available in Python. The extracted details are then matched with the institute database to verify the certificate. Another method involves using blockchain technology to verify certificates. This method includes obtaining the service content and exchange record of the certificate from a blockchain data table, verifying the service content and exchange record using verification keys and signature public keys, and determining the validity of the certificate based on the verification results. Additionally, there is a method that involves acquiring the original certificate image, extracting feature information, and generating a certificate authenticity verification conclusion sheet based on the checking results. Another method involves acquiring image information of the certificate at different angles, performing feature detection, and determining the authenticity of the certificate based on the color-changing ink values. Lastly, there is a method that involves acquiring the image of a certificate under different acquisition conditions and determining the possibility of the image coming from the original certificate based on the coating characteristics.

Can the post-hoc analysis be used to determine the effect size in a study?
4 answers
Post-hoc analysis should not be used to determine the effect size in a study. Post-hoc power calculations are deemed misleading and uninformative for data interpretation. Researchers argue that post-hoc power calculations, which assume the observed effect size equals the true population effect size, are flawed due to random variation leading to inconsistent results between studies. Despite suggestions to disclose power even below 80%, it is considered a bad idea as achieving 80% power in surgical studies is challenging. Additionally, post-hoc analyses, such as in the aducanumab trials, are under scrutiny for their potential to influence drug approval decisions. Therefore, relying on post-hoc analysis to determine effect size is discouraged due to its limitations and potential for misinterpretation.
