Flood attacks generation
Hudec, David
Proposal of a high speed packet flooding device is presented in this paper. The product is based on the FPGA (Field-programmable Gate Array) platform, developed in VHDL (Very high speed integrated circuit Hardware Description Language) and set into the NetCOPE environment. It uses an existing solution of packet generator. Once done, it should be implemented on a COMBO-80G board to serve as a network stressing tool.

Design and implementation of Twofish cipher on the FPGA network card
Cíbik, Peter ; Martinásek, Zdeněk (referee) ; Smékal, David (advisor)
This bachelor thesis deals with implementation of block cipher Twofish on the FPGA platform in VHDL language. The teoretical introduction explains basics of cryptography and symetric ciphers block operation modes, FPGA platform and introduction to VHDL language. In the next part the Twofish cipher, its components and flow are being dis- cussed in depth. Subsequently describes design of Twofish cipher in VHDL language and induvidual steps in this process. The last part deals with own implementation on hardware card with FPGA chip and summarizes reached goals.

Virtualization of I/O Operations in Computer Networks
Remeš, Jan ; Martínek, Tomáš (referee) ; Matoušek, Denis (advisor)
This work deals with virtualization of computer systems and network cards in high-speed computer networks, and describes implementation of the SR-IOV virtualization technology support in the COMBO network card platform. Various approaches towards network card virtualization are compared, and the benefits of the SR-IOV technology for high performance applications are described. The work gives overview of the COMBO platform and describes design and implementation of the SR-IOV technology support for the COMBO platform. The work concludes with measurement and analysis of the implemented technology performance in virtual machines. The result of this work is the COMBO cards' support for the SR-IOV technology, which makes it possible to use them in virtual machines with wire-speed performance preserved. This allows future COMBO cards to be used as accelerators in the networks utilizing the Network Function Virtualization.

Simulation of cryptographic algorithms using FPGA
Németh, František ; Mašek, Jan (referee) ; Smékal, David (advisor)
Bachelor thesis is dealing with a cipher standard AES and with a design of encryption and decryption components for AES in special modes of operation. Programming language is VHDL. In theoretical part of thesis is a further descriptions of AES and behaviour of block cipher operation modes. Furthermore the brief description of VHDL, FPGA and NetCOPE framework is a piece of theoretical part as well. The practical part contains designs which are made in developing environment Vivado from Xilinx. Programmed modes of operation are ECB, CBC, CTR and CFB. Simulation outputs and synthesis results are summerized in tables.

Implementation of cryptographic algorithms on the FPGA platform
Zugárek, Adam ; Sládok, Ondřej (referee) ; Smékal, David (advisor)
This bachelor’s thesis describes methods of data encryption and author’s own implementation on FPGA. The goal of this thesis is to implement cipher on a hardware accelerated network card COMBO. In the introduction is described encryption using block ciphers. Cipher AES was chosen to implement, which is famous and most using cipher. Its detailed description is described in the first part of the thesis. In the second part is described the author’s own implementation of AES cipher in VHDL. In the next part is method of interconnecting the resulting program with a framework of the FPGA card – NetCOPE. Achieved results are in the end of this thesis. The resulting program cannot encrypt network communication. It only transforms data stored in the card, which then send to host computer.

Packet generator on the FPGA platform
Bari, Lukáš ; Blažek, Petr (referee) ; Smékal, David (advisor)
The thesis deals with the theory and design of the network traffic generator on the FPGA platform. The VHDL programming language is used for the description. The work involves getting acquainted with the development processes and design tools needed to create the overall project. It also includes familiarity with the necessary FPGA, NetCOPE and COMBO cards. Based on this information, was designed, tested and implemented packet generator project for the Combo-80G card. For implementation was used framework from NetCOPE.

Measurement parameters of communication via PCI Express
Dujiček, Ondřej ; Dvořák, Vojtěch (referee) ; Pristach, Marián (advisor)
This bachelor thesis deals with parameters affecting throughput of PCI Express bus and its main result is a design and implementation of a unit for measuring parameters of communication over PCI Express bus. The unit is implemented in VHDL language and its support on generating and measuring traffic at speeds up to 100 Gbps. Unit’s operation frequency, when implemented in Virtex 7 available at COMBO-100G , is 200 MHz. The implemented unit is controlled from software through MI32 interface and it is able to measure the amount of transferred packets and data in both receive and transmit directions. This information can be exported into software using MI32 interface.

Generating of flood attacks
Hudec, David ; Hajný, Jan (referee) ; Smékal, David (advisor)
The assessment comprises of two parts, describing theory and generating of flood attacks respectively. The first part covers flood attacks' analysis, deals with their available techniques and practices, known in the area, and a computer simulation program, revealing the behavior of a contested network as well as the attacker's procedure. In the following part, data generating solutions itself are described. These are represented by two hardware programs, adapted from existing solutions, and one C# application, created by the author. The comparison of these two approaches is included, as well as are the generation results and mitigation proposal.

Porting NetCOPE Platform to EDK
Palička, Jan ; Košař, Vlastimil (referee) ; Viktorin, Jan (advisor)
This bachelor's thesis deals with porting of NetCOPE to Xilinx Embedded Development Kit (EDK). Main task is to create annotation of NetCOPE hardware for using in EDK. Before implementation of annotation itself, it is necessary both to study FPGA technology, possibilities of FPGA progamming, NetCOPE platform and PSF for anotation of NetCOPE’s IP-core.
