  1. 1. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :John Alanko Öberg; Carl Svensson; [2023]
    Nyckelord :Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

    Sammanfattning : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. LÄS MER

  3. 2. Clueless: A Tool Characterising Values Leaking as Addresses : Clueless: A Tool Characterising Values Leaking as Addresses

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Xiaoyue Chen; [2022]
    Nyckelord :;

    Sammanfattning : A fundamental programming feature that allows Spectre to effortlessly leak the value of secrets via cache side channels is the transformation of data values into addresses. Consider forexample sorting, hashing, or many other algorithms that create addresses based on datavalues. LÄS MER

  4. 3. An analysis of reported phishing domains

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Tim Hellberg; Daniel Keyvanpour; [2019]
    Nyckelord :;

    Sammanfattning : As we become more digitalized and we rely more heavily on the internet, the more important it is to protect ourselves against phishing attacks and other types of internet frauds. Users who fall for phishing attacks risk getting sensitive information stolen such as their bank accounts. LÄS MER

  5. 4. Hashing algorithms : A comparison for blockchains in Internet of things

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Författare :Karl Dahlin; [2018]
    Nyckelord :Internet of things; Blockchain; Hash; Hashing algorithms; MD5; SHA; C ; Matlab;

    Sammanfattning : In today’s society blockchains and the Internet of things are two very discussed subjects this has led to thoughts about combining them by using a blockchain in Internet of things. This objective of this study has been to solve the problem which hashing algorithms is the best for a blockchain used in an Internet of things network. LÄS MER

  7. 5. Investigation of cryptographic algorithms for the transfer of financial information

    Magister-uppsats, Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Mykola Martynenko; [2010]
    Nyckelord :encryption; cryptography; hashing; client; server; compressing; digital signature;

    Sammanfattning : The purpose of the investigation is to determine the most effective solution, which allows safe storing and transmitting of financial information in terms of execution speed, resistance to hacking and ease of implementation. Research object is subject area related to the transfer of encrypted financial information like: encryption algorithms, algorithm of hashing functions, algorithm of electronic digital signature.
