  1. 1. LSTM-attack on polyalphabetic cyphers with known plaintext : Case study on the Hagelin C-38 and Siemens and Halske T52

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oriol Closa; [2023]
    Keywords : ;

    Abstract : Polyalphabetic cyphers have been used for centuries and well into the 1970s to transmit all kinds of messages. Since then, computers and modern cryptography have taken over making bruteforce attacks unfeasible when designed properly. READ MORE

  3. 2. Automated Generation of EfficientBitslice Implementations forArbitrary Sboxes

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Augustin Bariant; [2023]
    Keywords : Bitslicing; Cryptography; Whitebox; Compilation; Boolean circuits.; Parallélisation au bit; Cryptographie; Boîte blanche; Compilation; Circuits booléens.; Bitslicing; Kryptografi; Vit låda; Kompilering; Booleska kretsar.;

    Abstract : Whitebox cryptography aims at protecting standard cryptographic algorithmsthat execute in attacker-controlled environments. In these, the attacker is ableto read a secret key directly from memory. Common implementations mask alldata at runtime and operate on masked data by using many small precomputedtables. READ MORE

  4. 3. Fuzzing of PKCS#11 Trusted Application

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

    Author : Kevin Zeng; [2022]
    Keywords : Fuzzing; white-box; PKCS#11; OP-TEE; AFL; Open-TEE; TA; Trusted Application; Technology and Engineering;

    Abstract : The main goal of this thesis is to find an effective way to fuzz trusted applications (TAs) with source code residing in trusted execution environment (TEE). While fuzzing TAs has been previously done, no work has been found to utilize the source code of TAs to improve the fuzzing. READ MORE

  5. 4. Fair Voting System for Permissionless Decentralized Autonomous Organizations

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Erik Hellström; [2022]
    Keywords : blockchain; dao; crypto; cryptocurrency; p2p;

    Abstract : The increasingly adapted technology called blockchain can be viewed as a distributed append-only time-stamped data structure which is made possible by a distributed peer-to-peer network. The network uses cryptography and different consensus mechanisms to ensure immutability, security, transparency, and speed in a decentralized fashion. READ MORE

  6. 5. How is Polly? Revisiting the Differential Attack on Polly Cracker after 20 years

    University essay from Lunds universitet/Matematikcentrum

    Author : Christoph Strobl; [2022]
    Keywords : Gröbner Bases; polly cracker; differential attack; asymmetric cryptography; multivariate cryptography; public-key cryptography; Mathematics and Statistics; Technology and Engineering;

    Abstract : För att skapa nya krypteringsalgoritmer är man alltid på jakt efter svårlösta matematiska problem. Men är alla problem lämpliga? Uppsatsen behandlar Gröbnerbaser över ändliga kroppar och visar att de är inte lämpliga för att bygga säkra krypteringsalgoritmer. READ MORE
