Možnosti zabezpečených datových přenosů v bezdrátových sítích

Abstract

The work describes the possibilities of securing wireless networks. It deals mainly with the network security standard IEEE 802.11. However, security in the original standard was inadequate; this work describes and compares security add-ons to this standard. The work describes the principles of authentication, encryption and integrity of transmitted data for different types of security. It refers to the advantages and disadvantages in the use of certain methods of protection, then the described methods are shown on examples of configurations. In conclusion, the work is proposed to typical network security infrastructures, such as network topology ISP, company or household, where appropriate, small offices. Consequently, this issue is design as a supplement in the form of web pages and Macromedia FLASH technology.
