Data authentication

An embedded device is becoming popular in daily life thanks to their low power consumption and multiprocessing capability. In particular, the security of embedded devices has been a big issue of concern to academic and industrial communities. This study aims at the Grain 128- AEAD authenticated encryption with associated data algorithm embedded on low-power and resourceconstrained devices.

This study employs a structural equation model to investigate the behavior of slow tourism and examine the impact of existential authenticity and object-based authenticity on slow behavior intention. Data was collected from 518 tourists who had visited Thua Thien Hue at least once. The findings reveal that both object-based authenticity and existential authenticity indirectly impact intention through personal factors.

In this work, one of the methods deploying encryption to cipher data is represented. The primary object of this project is applying Advanced Encryption Standard (AES) in communications based Orthogonal Frequency Division Multiplexing (OFDM). This article discusses the security of the method encrypting directly QAM symbols instead of input bit-stream.

RIP version 2 is not a new protocol—it is RIP Version 1 with some additional fields in the route update packet, key among them being subnet mask information in each route entry. The underlying DV algorithms in RIP-2 are identical to those in RIP-1, implying that RIP-2 still suffers from convergence problems and the maximum hop- count limit of 16 hops.

Users and Security Security domain The database administrator defines the names of the users who are allowed to access a database. A security domain defines the settings that apply to the user. Authentication mechanism A user who requires access to the database can be authenticated by one of the following: Data dictionary Operating system Network The means of authentication is specified at the time the user is defined in the database and can be altered later. This lesson covers authentication by database and by operating system only.

Initialization Parameter Files In order to start an instance and open the database, you must connect as SYSDBA and enter the STARTUP command. The Oracle server will then read the initialization parameter file and prepare the instance according to the initialization parameters contained within. Note: You must have SYSDBA privilege. Authentication and the SYSDBA privilege will be discussed in later lessons.
