  1. 1. FFS: A cryptographic cloud-based deniable filesystem through exploitation of online web services : Store your sensitive data in plain sight

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

    Author : Glenn Olsson; [2023]
    Keywords : Filesystem; Fejk FileSystem; Cloud-based filesystem; Steganograhpic filesystem; Filsystem; Fejk FileSystem; Molnbaserat filsystem; Steganografiskt filsystem;

    Abstract : Many Online Web Services (OWSs) today, such as Flickr and Twitter, provide users with the possibility to post images that are stored on the platform for free. This thesis explores creating a cryptographically secure filesystem that stores its data on an online web service by encoding the encrypted data as images. READ MORE

  3. 2. Tribonacci Cat Map : A discrete chaotic mapping with Tribonacci matrix

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Linnea Fransson; [2021]
    Keywords : Arnold s cat map; Tribonacci matrix; chaotic map; discrete dynamical system; linear recurrence sequence; Trisano period; 3D image encryption; colour encryption;

    Abstract : Based on the generating matrix to the Tribonacci sequence, the Tribonacci cat map is a discrete chaotic dynamical system, similar to Arnold's discrete cat map, but on three dimensional space. In this thesis, this new mapping is introduced and the properties of its matrix are presented. READ MORE

  4. 3. Digital incursion: Breaching the android lock screen and liberating data

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Tim Oskarsson; [2021]
    Keywords : Android forensics; Mobile forensics; Memory forensics; Device access; PIN; Pattern; Biometrics; Android Debug Bridge; TWRP; Frida.;

    Abstract : Android is the most used operating system in the world, because of this the probability of an android device being acquired in an investigation is high. To begin to extract data from an android device you first need to gain access to it. Mechanisms like full system encryption can make this very difficult. READ MORE
