Virtual serial port and its safety conversion to Ethernet
Pokorný, Michal ; Krajsa, Ondřej (referee) ; Koutný, Martin (advisor)
Bachelor´s thesis try to find a solution to make virtual serial port and its safe transfer on Ethernet. Nowdays communications channels don't offer appropriate security of a whole communication. Therefore it depends on get-togethers, in order to realize this security themselves.This means ensure reliable data transfer, these data from among get-togethers encrypt in order to appropriate attacher be unable to read them in real - time, eventually to change them. As a result this Bachelor thesis is the application, which, except transfer between virtual serial port and Ethernet, insure authentication among get - togehthers communication and cipher transfer among them. As an encryption algorithm is used algorithm AES. It is concerned symmetrical cipher, which ciphers data after pages about size 128 byte.

Web Gateway for Access to Measurement Devices
Zsíros, Anton ; Barabas, Maroš (referee) ; Hanáček, Petr (advisor)
This Master's thesis deals with design and implementation of a system that can access remote devices through computer network. Specifically, the serial port devices and audio input devices. The first step of the thesis was to do a survey in the field of similar available, focusing on applications that could be integrated into the final system. For serial port devices, it was necessary to find a solution that would allow redirecting data from the physical device to a computer network and creating virtual serial ports on client systems, through which would users access these devices. To transfer audio streams from audio input devices through computer network was chosen RTP protocol, which is well suited for data transmission in real time. The thesis also contains the description of handling received RTP stream on a client system. The result is a complex system that integrates the functionality of mentioned tools into a single unit.

Secure converter for an RS-232 standard to the Internet
Pokorný, Michal ; Mlýnek, Petr (referee) ; Koutný, Martin (advisor)
Master´s thesis tries to find a solution to make a secure transmission channel between virtual serial ports on the personal computer and the serial ports on the Rabbit RCM3700 development KIT. Today’s communications channels don't offer appropriate security of a whole communication. Therefore it depends on get-togethers, in order to realize this security themselves. This security means ensuring reliable transmission of data to be encrypted between parties so that any attacker is not able to read real-time, or eventually change them. As a result of this Master thesis is the design and implementation, which in addition to encryption algorithm provides sufficient security and authenticity of communication between the parties. As an encryption algorithm has been chosen widely used AES algorithm and as authentication algorithm has been chosen algorithm, which for authenticity requires knowledge of the secret key.
