  1. 16. On Asynchronous Group Key Agreement : Tripartite Asynchronous Ratchet Trees

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

    Author : Phillip Gajland; [2020]
    Keywords : MLS; secure messaging; cryptography; MLS; säker meddelandehantering; kryptografi;

    Abstract : The subject of secure messaging has gained notable attention lately in the cryptographic community. For communications between two parties, paradigms such as the double ratchet, used in the Signal protocol, provide provably strong security guarantees such as forward secrecy and post-compromise security.

  3. 17. Randomly perturbing the bytecode of white box cryptography implementations in an attempt to mitigate side-channel attacks

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

    Author : Alexander Koski; [2020]
    Keywords : ;

    Abstract : This study takes one step further towards constructing a tool able to automatically amplify the security on your cryptographic implementations. In white box cryptography the encryption key is hidden inside the encryption algorithm out of plain sight. READ MORE

    Keywords : Steganography; Steganalysis; Watermarking; Information hiding; Cryptography; Compression; Non-intrusive; Sturdy; JPEG; Steganografi; Steganalys; Vattenmärkning; Kryptografi; Kompression; Icke störande; Stabil; JPEG;

    Abstract : It is desirable for companies to be able to hide data inside videos to be able to find the source of any unauthorised sharing of a video. The hidden data (the payload) should damage the original data (the cover) by an as small amount as possible while also making it hard to remove the payload without also severely damaging the cover.
