  1. 1. Exploring true random number generators Build on commercial-off-the-shelve Components

    M1-uppsats, Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

    Författare :Linnéa Mörk; [2023]
    Nyckelord :TRNG; RNG; Random number generator; commercial-off-the-shelve;

    Sammanfattning : Generating random numbers can be accomplished through various methods, with the primary distinction lying between pseudo-random number generators (PRNGs), which are commonly used for applications that require a large amount of random data, and true random number generators (TRNGs), which are commonly used for applications that need security and unpredictability. This thesis explores the feasibility of harnessing frequency variations in the electrical grid as a source of entropy for a TRNG. LÄS MER

  3. 2. Implementing and Evaluating the Quantum Resistant Cryptographic Scheme Kyber on a Smart Card

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Hampus Eriksson; [2020]
    Nyckelord :post-quantum; cryptography; lattice-based cryptography; quantum-resistant; Kyber; constrained device; performance; evaluation; implementation;

    Sammanfattning : Cyber attacks happen on a daily basis, where criminals can aim to disrupt internet services or in other cases try to get hold of sensitive data. Fortunately, there are systems in place to protect these services. And one can rest assured that communication channels and data are secured under well-studied cryptographic schemes. LÄS MER

  4. 3. Analysis of Entropy Usage in Random Number Generators

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Joel Gärtner; [2017]
    Nyckelord :Random; vulnerability; Entropy; CSPRNG; RNG; TRNG; PRNG; LRNG; Linux; Estimate; HAVEGED; PRNGD; FreeBSD; Overestimate; Linux Random Number Generator; Cryptography; Random Number Generator; Seed; Predictors; Markov Chains;

    Sammanfattning : Cryptographically secure random number generators usually require an outside seed to be initialized. Other solutions instead use a continuous entropy stream to ensure that the internal state of the generator always remains unpredictable. This thesis analyses four such generators with entropy inputs.

  5. 4. Development of a FPGA-based True Random Number Generator for Space Applications

    Master-uppsats, Elektroniksystem

    Författare :Prassanna Shanmuga Sundaram; [2010]
    Nyckelord :True random number generator; cryptography; random jitter; FPGA; VHDL; ring oscillator; astable oscillator; statistical tests;

    Sammanfattning : Random numbers are required for cryptographic applications such as IT security products, smart cards etc. Hardwarebased random number generators are widely employed. Cryptographic algorithms are implemented on FieldProgrammable Gate Arrays (FPGAs). LÄS MER

  7. 5. Slumptalsgeneratorer för Säkerhetssystem

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Toni Nijm; [2002]
    Nyckelord :Datorteknik; RNG; PRNG; TRNG; krypteringsnyckel; slumptal; diehard; FIPS; Datorteknik;

    Sammanfattning : Slumptalsgeneratorer är bland de viktigaste byggblocken inom dagens säkerhetssystem och infrastruktur. Det finns dock en uppsjö av varierande implementeringsmodeller i såväl mjukvara som hårdvara. Att konstruera en slumptalsgenerator som har tillträckligt bra egenskaper för att användas i säkerhetssystem är inte någon trivial uppgift. LÄS MER
