    Keywords : block encryption; image cryptography; DNA; chaos; SHA-256;

    Abstract : The emerging topic, symmetric encryption technique for digital imagesusing chaotic function and DNA bases has recently drawn a lot ofattentions from the research community. The use of voice and visualmaterial as an addition to textual data has become more widespread. READ MORE

  3. 22. Evaluation of VPNs

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Mustafa Al-Abaychi; Joanna Ellvin; [2016]
    Keywords : ;

    Abstract : This thesis evaluated the performance of four different virtual private networks (VPNs): IP security (IPsec), OpenVPN, SSH port forwarding and SSH using virtual interfaces. To evaluate these VPNs, three comparative performance tests were carried out in which the maximum throughput of each VPN was measured. READ MORE

  4. 23. Power Analysis of the Advanced Encryption Standard : Attacks and Countermeasures for 8-bit Microcontrollers

    University essay from Linköpings universitet/Informationskodning

    Author : Mattias Fransson; [2015]
    Keywords : power analysis; template attacks; countermeasures; microcontroller; AES;

    Abstract : The Advanced Encryption Standard is one of the most common encryption algorithms. It is highly resistant to mathematical and statistical attacks, however, this security is based on the assumption that an adversary cannot access the algorithm’s internal state during encryption or decryption.

  5. 24. Performance analysis of GPGPU and CPU on AES Encryption

    University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Author : Akash Kiran Neelap; [2014]
    Keywords : AES algorithm; CUDA; GPU computing; Pthreads;

    Abstract : The advancements in computing have led to tremendous increase in the amount of data being generated every minute, which needs to be stored or transferred maintaining high level of security. The military and armed forces today heavily rely on computers to store huge amount of important and secret data, that holds a big deal for the security of the Nation. READ MORE

  6. 25. Analysis of new and alternative encryption algorithms and scrambling methods for digital-tv and implementation of a new scrambling algorithm (AES128) on FPGA.

    University essay from Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska högskolan

    Author : Gustaf Bengtz; [2014]
    Keywords : DVB; scrambling; CISSA; cipher; CSA; CSA3; AES128; FPGA;

    Abstract : This report adresses why the currently used scrambling standard CSA needs a replacement. Proposed replacements to CSA are analyzed to some extent, and an alternative replacement (AES128) is analyzed. One alternative being the CSA3, and the other being the CISSA algorithm. Both of the proposed algorithms use the AES algorithm as a base. READ MORE
