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

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

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

    Abstract : 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. READ MORE

  3. 2. Proof of the security of the modified sphinx mixnet header format in the SPORES protocol : A verifiably secure onion routing protocol with indistinguishable replies

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

    Author : Benjamin Thellström; [2023]
    Keywords : ;

    Abstract : The internet inherently makes secret communication difficult, the entire basis of the IP-protocol is that the routers handling the packets need to know who is receiving the packet. However, there are many reasons why someone would want to communicate in secret. One possible solution is that of onion-routing. READ MORE

    Abstract : This thesis describes methods of secret communication based on latin squares and their close relative, quasigroups. Different types of cryptosystems are described, including ciphers, public-key cryptosystems, and cryptographic hash functions. There is also a chapter devoted to different secret sharing schemes based on latin squares. READ MORE
