Location Based Authentication
… of a genuine user. Today's conventional authentication mechanisms are based on three factors: knowledge, possession and biometrics. These factors are prone to theft, hardware failure, expensive, etc. Consequently, there is a need of a stronger solution. One such solution is Location Based …

Authentication scenario for CyberCIEGE
Frequent media reports of the loss or compromise of data stored on computer systems indicate that attempts to educate users on proper computer security policies and procedures seem to be ineffective. In an effort to provide a means of education that will more fully engage users, the CyberCIEGE game …

Authentication Based on Blockchain
… are offered by services providers which are use authentication, authorization and accounting framework based on client-server model. Though this model has been used over decades, study shows it is vulnerable to different hacks and it is also inconvenient to use for the end users. In addition, the …

Usable authentication for mobile banking
… The current mobile banking login method is PIN authentication; however, results from other research studies have found that there are usability concerns of using PINs. To overcome some of the concerns, researchers have suggested the use graphical passwords. In this research, we argue that …

Extensible Pre-Authentication in Kerberos
… basis. This paper presents EPAK (Extensible Pre-Authentication in Kerberos), a framework that enables Kerberos to operate as an open system. Implemented as a Kerberos extension, EPAK enables many authentication schemes to be loosely coupled with Kerberos, without further modification to Kerberos. …

Wireless Authentication Using Remote Passwords
Current authentication methods for wireless networks are difficult to maintain. They often rely on globally shared secrets or heavyweight public-key infrastructure. Wireless Authentication using Remote Passwords (WARP) mitigates authentication woes by providing usable mechanisms for both …

Usable authentication for mobile banking
… dissertation describes the design of two mobile authentication techniques: combinational graphical passwords and gesture passwords. These systems were implemented as prototypes. The prototypes along with a PIN authenticator were evaluated with users.

Authentication protocol using trapdoored matrices
… this thesis, we propose a new type of public-key authentication protocol, which is based on timing gaps. The honest user's secret key allows him to perform a task faster than any adversary. In our construction, the public key is a n x n matrix and the secret key is a trapdoor of this matrix. The …

A Multimodal Biometric Authentication for Smartphones
… as a viable solution to ageing password based authentication on smartphones. Fingerprint biometric is leading the biometric technology for smartphones, however, owing to its high cost, major players in mobile industry are introducing fingerprint sensors only on their flagship devices, leaving …

Continuous authentication on android mobile devices
Initial authentication methods, such as passwords and PINs, secure access to an Android mobile device only at login, leaving active sessions vulnerable to unauthorised access. With over 3.9 billion Android mobile users worldwide and the widespread use of ultra-short messages in applications like …

Authentication Schemes' Impact on Working Memory
<p>Authentication is the process by which a computing system validates a user’s identity. Although this process is necessary for system security, users view authentication as a frequent disruption to their primary tasks. During this disruption, primary task information must be actively maintained …

Continuous user authentication featuring behavioural biometrics
A user authentication method consists of a username, password, or any other related credential. These methods are mostly used only once to validate the user’s identity at the start of session or sometimes after regular interval of time which can lead to security loopholes. However, one-time …

Verification of secure biometric authentication protocols
The thesis presents verification of biometric authentication protocols. ProVerif is used as the verification tool for verifying and analysing the protocols. The protocol are analysed in ProVerif model. Various attacks to the protocols are generated in order to verify whether the protocols hold …

Transmitter Authentication in Dynamic Spectrum Sharing
… such threats is to employ a transmitter authentication scheme at the physical (PHY) layer. In PHY-layer authentication, an authentication signal is generated by the transmitter, and embedded into the message signal. This enables a regulatory enforcement entity to extract the …

Privacy Preserving Authentication Schemes and Applications
… of the two parties - service providers' need for authentication and the users' privacy needs - is the cause for this problem. Privacy Preserving Authentication could help solve both these problems by creating valid and anonymous identities for the users. And simply by proving the authenticity and …
