Information security is a major problem in cloud computing systems as the information may be physically placed anywhere in any data center throughout the networks. Due to the nature of cloud computing, user authentication, information integrity, and confidentiality are all brought up as significant challenges. In order to ensure confidentiality, integrity, and authentications while storing and accessing information from and to the data center as well as in peer contacts; it is advised to adopt a better, innovative, secure security method. Cloud security is a rapidly expanding area of computer and networks securities. In the cloud platforms paradigm, external data centers are used. It supports a range of programminglanguages used in the process of deploying web applications. The Cloud is built on a managed containers architecture that integrates information services and robust ecosystems for the deployment and operation of modern apps. In cloud computing, data securities are a major challenge that is dealt with using cryptographic methods. One potential method for encrypting data is the Advanced Encryption Standard (AES). After developing a cloud platform, the AES algorithm for encryption and the Data Encryption Standard (DES) method for decryption will be used in this work to secure data. The performance study suggests that DES and AES cryptography can be used to secure data. Calculations of data encryption and decryption delay also show that increased data delay periods are caused by bigger data volumes.

This article focuses on responding to today's ever- increasing demands for convenient and economical medical solutions, with special attention to the innovation of MRI systems with ultra-low magnetic field strengths of 0.1 Tesla and below. With its obvious advantages of being lightweight, compact and cost-effective, this type of MRI system is becoming an ideal way to expand the coverage of medical services to primary medical institutions and even remote areas. The article details a high-performance digital receiver specially designed to meet the technical challenges of ultra-low-field MRI. The receiver integrates the cutting-edge PXIe technology architecture and is based on National Instruments (NI). Hardware modules are core components. The research work not only includes systematic theoretical conception and specific implementation, but also includes a comprehensive practical verification process under laboratory conditions. Especially in a 50-milliTesla-level ultra-low-field MRI experimental setup, the researchers conducted in-depth system integration andfunctional performance testing of the digital receiver, and fine- tuned the receiving coil (RX Coil). Experimental evidence shows that this digital receiver developed based on the PXIe architecture exhibits excellent signal capture and processing performance in ultra-low field MRI environments. Thanks to this, combined with Nl's data acquisition (DAQ) hardware equipment and LabVIEW visual programming with this tool, the R&D team can efficiently complete the system construction and quickly put it into practical application within a short R&D period, thus effectively promoting the in-depth development and widespread application of ultra-low field MRI technology at the practical level.
