Identifying and validating the user is a major concern in a heterogeneous network domain. Conventional algorithms and mechanisms could authenticate the users/messages, but with certain vulnerabilities. This paper analyzes the vulnerabilities and downsides of some present-day authentication mechanisms that are being used and proposes an authentication mechanism that cannot be bypassed easily. The proposed mechanism incorporates multi-factor authentication and validates the user based on a username, a password, a security question which is sent to the user via Short-Message-Service (SMS), and a security pin (if necessary). List of security questions posed to the end-user makes the proposed mechanism stronger and protect the system from security breaches by an unknown user to guess the answer.

M2U2: Multifactor Mobile Based Unique User Authentication Mechanism

Cloud computing is an internet-based computing where shared resources, software and information provided to the end-users, on demand. The end users can be comfortable with the cloud as its features on-demand self-services, broad network access, resource pooling, rapid elasticity and measured service, make it more efficient. Security is one of the major issues which hamper the growth of cloud. Confidentiality–Integrity–Availability are the major security goals to be ensured by the security mechanisms. Authentication could provide a better solution in all three aspects. Various authentication based methodologies proposed by experts are in the field, with their own strength and weakness. This paper proposed an authentication scheme along with performance enhancement. Initial phase of the proposal differentiates the request as wired or wireless network. Based on which, appropriate authentication protocol comes into play, wired adopts keystroke behaviour and wireless follows SSID. In the second phase, users behaviour were analysed and credits assigned to them, based on which resource accessibility is restricted. In the third phase, performance characteristics were taken into account. Analytical results support the claim to enhance the security services and also the performance factors such as resource utilizations and cost.

User Authentication Framework with Improved Performance in Multi-cloudEnvironment

Some of the common works like, upload and retrieval of data, buying and selling things, earning and donating or transaction of money etc., are the most common works performed in daily life through internet. For every user who is accessing the internet regularly, their highest priority is to make sure that there data is secured. Users are willing to pay huge amount of money to the service provider for maintaining the security. But the intention of malicious users is to access and misuse others data. For that they are using zombie bots. Always Bots are not the only malicious, legitimate authorized user can also impersonate to access the data illegally. This makes the job tougher to discriminate between the bots and boots. For providing security form that threats, here we are proposing a novel RSJ Approach by User Authentication. RSJ approach is a secure way for providing the security to the user form both bots and malicious users.
