    Sammanfattning : Data permeates every aspect of our daily life and it is the backbone of our digitalized society. Smartphones, smartwatches and many more smart devices measure, collect, modify and share data in what is known as the Internet of Things. LÄS MER

  5. 4. Be More and be Merry: Enhancing Data and User Authentication in Collaborative Settings

    Författare :Elena Pagnin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Homomorphic Signatures; Server-Aided Verification; Distance-Bounding Authentication Protocols; Verifiable Com- putation; Biometric Authentication.;

    Sammanfattning : Cryptography is the science and art of keeping information secret to un-intended parties. But, how can we determine who is an intended party and who is not? Authentication is the branch of cryptography that aims at confirming the source of data or at proving the identity of a person. This Ph.D. LÄS MER

  7. 5. Secure and Privacy-Preserving Cloud-Assisted Computing

    Författare :Georgia Tsaloli; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; differential privacy; decentralization; verifiability; privacy-preservation; secure aggregation; secret sharing; cloud computing; privacy;

    Sammanfattning : Smart devices such as smartphones, wearables, and smart appliances collect significant amounts of data and transmit them over the network forming the Internet of Things (IoT). Many applications in our daily lives (e.g., health, smart grid, traffic monitoring) involve IoT devices that often have low computational capabilities. LÄS MER
