Identity management : strengthening one-time password authentication through usability

摘要: Usability in HCI (Human-Computer Interaction) is normally understood as the simplicity and clarity with which interaction a computer program or web site designed. Identity management systems need to provide adequate usability should have simple intuitive interface. The system not only be designed satisfy service provider requirements but it has consider user requirements, otherwise will lead inconvenience poor for users when managing their identities. With interface regard security, highly likely that security. rapid growth number of online services leads an increasing different digital identities each needs manage. As result, many people feel overloaded credentials, turn negatively impacts ability manage them securely. Passwords are perhaps most common type credential used today. To avoid tedious task remembering difficult passwords, often behave less securely by using low entropy weak passwords. Weak passwords bad password habits represent security threats services. Some solutions been developed eliminate create A typical solution based on generating one-time i.e. single session transaction usage. Unfortunately, these do scalability and/or they simply insecure. In this thesis, aspects contemporary methods authentication (OTP) examined analyzed. addition, more scalable good experience while at same time preserving strong proposed.
