1. Preserving Privacy in Cloud Services by Using an Explainable Deep-Learning Model for Anomaly Detection
Master-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : As cloud services become increasingly popular, ensuring their privacy and security has become a significant concern for users. Cloud computing involves Data Service Outsourcing and Computation Outsourcing, which require additional security considerations compared to traditional computing. LÄS MER
2. LSTM-attack on polyalphabetic cyphers with known plaintext : Case study on the Hagelin C-38 and Siemens and Halske T52
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
3. An Arrow Metalanguage for Partially Invertible Computation
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Programming languages traditionally describe computations going one way: a program might compute a hash value from a string, or an encrypted message from a plaintext. However, sometimes it is also of interest to go the other way around: for encryption, we not only want to encrypt messages but also to decrypt them, and to be sure that the decryption correctly reproduces the original message.

4. Polybius Square Ciphers
Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)Sammanfattning : In this thesis, we will define Polybius Square Ciphers and explain howit used to encrypt plaintext. We will talk about Playfair, ADFGX andADFGVX. We will introduce how Shannon entropy works and its principalproperties. LÄS MER
5. PET-Exchange: A Privacy Enhanced Trading Framework : A Framework for Limit-Order Matching using Homomorphic Encryption in Trading
Master-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : Over the recent decades, an increasing amount of new traders has entered the securities markets in order to trade securities such as stocks and bonds on electronic and physical exchanges. This increase in trader activity can largely be attributed to a simpler trading process including the growth of the electronic securities exchanges allowing for more dynamic and global trading platforms.
