Increased trustworthinesss for online authentication

Contemporary authentication solutions for online applications are growing in sophistication and complexity to enhance security, privacy and convenience. For example, they are shifting from traditional username/password combinations to multi-factor and/or password-less authentication, and are leveraging biometric authentication factors on the user's mobile device. However, this growing sophistication is also offering new opportunities for cyber-criminals to compromise online authentication. Attacks are on the rise, and the trustworthiness in online authentication is being challenged, especially in single sign on configurations. This thesis will survey and investigate threats and countermeasures, and research, develop and evaluate methods that strengthen online authentication to become secure and trustworthy in adversarial settings. Prototypical solutions will be applicable in a middleware context. Tentative bibliography of relevant sources: [1] M. Ghasemisharif, A. Ramesh, S. Checkoway, C. Kanich, and J.
