Abstract |
: |
A multilevel security (MLS) is a familiar scheme of classification in the national security hierarchy, which partitions subjects into levels such as secret, top-secret, confidential, and unclassified. These networks may combine several security levels such as message digest, data compression, encryption, and smart card technology, respectively. These levels can work together to establish top security services such as data integrity, confidentiality, authentication, non-repudiation, availability, and access control. MLS systems can be used to protect network resources and corporate information from unauthorized access. They can be applied in many applications as authenticating banking retail transactions, authenticating transactions between governments and businessmen. It authenticates the identity of network users and network entities. It protects the integrity of electronic funds transfers for achieving the integrity of software and databases. It is also used in military and electronic commerce to provide secrecy and integrity for Internet transactions. This paper investigates design and evaluates performance of MLS computer networks. The study includes the impact of different security levels on network performance. A complete technical specification, design architecture, for an MLS network will be explained. Comparison between encryption algorithms implemented in the network will be achieved. A percentage of overhead time for establishing each security service at each security level is computed with respect to the total system time at the transmitter and the receiver in the network, respectively as function of packets file size. |
