A tutorial on blockchain and applications to secure network control-planes

Wireless sensor networks are networks that include hundreds to thousands of autonomous distributed devices. These sensors are used to monitor physical and environmental conditions. Reliable routing protocols are designed to build a reliable and secure network with power management and control overhead and congestion. The wireless medium allows malicious user?s wireless sensor networks (WSN) to take part in actions to get a damaging attack on network control nodes. Due to the proprietary nature of such networks, they are more complex and lack tamper-resistant hardware. Security mechanisms are more wit due to the wireless and transient computing or communication complexity of communication relationships between nodes in a network. The existing method doesn?t provide security in inconvenient network performance, and the attackers modify the data and damage it. The proposed blockchain method is fixed at the same level of security, such as Polynomial Ephemeral Blockchain-based Secure Routing (PEBSR) encryption, to create a secure network. In this method, first, to authenticate the neighbor node validate using a Polynomial Ephemeral key-based Neighbor node authentication method. It evaluates the node location trust node and distributes the Ephemeral key in this key established between the nodes to communicate securely. The second method provides a cryptography chain network, and it maintains each node information in the sink database in this process if any attacker or anyone modifies the data is stored on each individual database. Finally, to find the route between each sink and participate nodes in the network. In this proposed PEBSR method, simulation results in providing efficient security, throughput, and less response time; they are compared to the existing method.

Mail System

AbstractWWW-based user interface is presented for secure electronic mail service for healthcare users. Using this method, communications between an electronic mail (WWW) server and users (WWW browsers) can be performed securely using Secure Socket Layer protocol-based Hypertext Transfer Protocol (SSL-HTIP). The mail can be encrypted, signed, and sent to the recipients and vice versa on the remote WWW server. The merit of this method is that many healthcare users can use a secure electronic mail system easily and immediately, because SSL-compatible WWW browsers are widely used and this system can be made available simply by installing a WWW-based mail user agent on a mail server. We implemented a WWWbased mail user agent which is compatible with PEM-based secure mail and made it available to about 16,000 healthcare users. We believe this approach is effective in facilitating secure network-based information exchange among medical professionals.
