  1. 1. An Optimized Hardware Implementation of Grain-128AEAD

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Mattias Sönnerup; Ripudaman Khattar; [2019]
    Keywords : Technology and Engineering;

    Abstract : With the Internet of Things era being here, more devices than ever are connected to the Internet, making the need for higher security greater. One important aspect of security to consider is encryption, which protects data from being read by unauthorized parties. READ MORE

  2. 2. Studies of Cipher Keys from the 16th Century : Transcription, Systematisation and Analysis

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Crina Tudor; [2019]
    Keywords : keys; ciphers; historical keys; cryptography; key transcription;

    Abstract : In historical cryptography, a cipher key represents a set of rules by which we can convert between plaintext and ciphertext within an encryption system. Presently, there are not many studies that focus on analysing keys,especially not on a large scale or done in a systematic manner. READ MORE

  3. 3. Implementation and Benchmarking of a Crypto Processor for a NB-IoT SoC Platform

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sébastien Fuhrmann; Luis Cavo; [2018]
    Keywords : 3GPP; IoT; HLS; security; cryptography; AES; SNOW; ZUC; hardware; ASIC; confidentiality; integrity; cipher; Technology and Engineering;

    Abstract : The goal of this Master’s Thesis is to investigate the implementation of cryptographic algorithms for IoT and how these encryption systems can be integrated in a NarrowBand IoT platform. Following 3rd Generation Partnership Project (3GPP) specifications, the Evolved Packet System (EPS) Encryption Algorithms (EEA) and EPS Integrity Algorithms (EIA) have been implemented and tested.

    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

  5. 5. Constructions for efficient MDS diffusion layers

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

    Author : Nikolaos Tatsis; [2017]
    Keywords : ;

    Abstract : Matrices are widely used in Block Cipher Diffusion layers, usually chosen for offering maximal branch numbers, and allowing lightweight hardware implementations through their low XOR Count. When implemented in software however, is XOR Count the only metric? This project will utilize the parallelism provided by modern SIMD vector instructions to evaluate metrics, by implementing different algorithmic approaches. READ MORE
