Abstract

Objective: To provide Password authentication by cloud through performing tri stages and also to improve the security. Method: First stage is registration phase; it involves issuing of cloud space to user. Cloud space is used for storing all self information of the client which is used for checking authenticity for later usage. Password of user is generated by user or by server based on password user can registered into cloud. If registration process is completed, then users are able to access the server log-in whenever they needed. Protocol based verification and authentication for two different mediums (Duos) uses user's cell phones or mobile devices is used as SMS to avoid hacking of password and backtrack attack using password. Using unique phone number Duos system possesses website and involves a telecommunication service provider in recovery and registration phase-in Duos based authentication system user want to remember only the Long-Term Password (LTP) for login in all websites. Efficient and affordable authentication is provided by Duos. For successful login of user's, they need valid smartcard and correct password. It involves two-factor password phase and cloud space. Findings: Users able to change their password freely in password changing phase and update his/her information to cloud space. Applications/Improvements: The secured web authentication done successfully by using two types of registration which are named as Registration on Website and on the Mobile device. The scalability of the device is achieved.

Abstract

Microwaves ad-hoc feeler groups are spatially distributed self governing sensors to examine physical or environmental conditions and for conveyance purposes. Besides all the comforts of the life wireless network spouses serious security threats. Here we implement a simulation based model by using both dynamic threshold algorithm and recursive algorithm and hidden terminal process is used to transfer the data packets to the outer region nodes without any hazards. The proposed method detects the attack and restrain from the attacker node in the network based on CS (Cognitive Sensing) node.

Abstract

Objectives: The condition monitoring was done during the machining of Stainless Steel 316 Grade using a PCB microphone with a view to related the measured Sound Signal with the nozzle wear obtained. Methods/Statistical Analysis: It is done by using a Data Acquisition Device is used to connect the Computer with the microphone to analyze the signal using LAB VIEW Software. Also a Sensor signal conditioner is attached to the microphone to boost the sound signal. The machining is done by changing the abrasive flow rate and pressure parameters and the corresponding sound signal is recorded Findings: Regression analysis was carried out using Minitab 17 software and results showed that abrasive flow rate has more influence on nozzle wear rate. Regression equations were also developed for each nozzle hour based on process parameters. Also it was observed that the nozzle exit diameter increases with increase in nozzle life time. Application/Improvements: The future aspects are to develop a generalized equation for the nozzle wear rate based on the process parameters to develop a closed loop system.
