In view of the current limitations of Internet security,it designed a system of encryption and authentication base on Internet system. It detail realizes network security features of data confidentiality, data integrity, data origin authentication and access control and so on. Combine the actual application, it given specific implementation of the encryption and authentication.
Network coding, whose intermediate nodes decode and encode packets to forward incoming packets, increases the capacity the multicast network. However there are security issues of confidentiality and integrity which degrade and threat network coding. In this paper, we propose secure key checksum (SKC), a secure mechanism using an encryption key, to provide both confidentiality and integrity. To provide...
Providing desirable data security, that is, confidentiality, authenticity, and availability, in wireless sensor networks (WSNs) is challenging, as a WSN usually consists of a large number of resource constraint sensor nodes that are generally deployed in unattended/hostile environments and, hence, are exposed to many types of severe insider attacks due to node compromise. Existing security designs...
