Cloud computing is an architectural concept that offers computation and storage space as a service as well as on-demand, dynamic access to any type of service over the Internet. Storage as a service is one of the major services offered. Data are stored and managed at a cloud provider's data centre using cloud computing services, which are entirely internet-based technology. Traditional cryptographic security based on the assumed difficulty of computer operations is facing tremendous challenges as a result of the evolution of information technology. The key concerns with cloud servers are successful safe communication and protecting sensitive data from unauthorized access on public networks. This protocol can be implemented using the exclusive-OR operation in traditional cryptography. Data security issues and supporting data security architecture are the key targets of this investigation. In the same way that it chooses a server for data storage that is quick, efficient, and light on resources, the system is made to prepare security procedures regardless of the order in which the data is stored. Cuckoo Search Algorithm (CSA) has been used to determine which available server is most suitable for a given task in wake-sleep distributed computing. Homomorphic encryption, where information is encrypted before being delivered to the server, is typically used to guarantee the veracity of the data being transmitted. To save on server resources and data storage, we've encrypted everything with ECDSA on the cloud server. It strengthens protections for user data in the cloud. At the end of the day, the system proves that data is secure, reliable, and private. Despite some drawbacks, this framework does provide safe methods of exchanging keys and backing up data, both of which are crucial for protecting the confidentiality of sensitive data kept in the cloud.

The cloud customer is typically uninformed of the provider's threat assessment and mitigation procedures. Ask what safety precautions the service provider takes. So, the client must likewise do something to improve the supplier's security. The function of quantum key distribution (QKD) in cryptographic infrastructures is investigated in this work. QKD uses quantum mechanical systems to promise safe key agreements. There is a claim that QKD will play a significant role in upcoming cryptographic infrastructures. Without relying on computational assumptions, it can guarantee long-term confidentiality for encrypted data. In fact, even when using public-key authentication, we contend that QKD still provides stronger security than conventional key agreements. Several researchers have put forth various data recovery strategies, but they are ineffective and unreliable. When the primary cloud server loses its data and is unable to offer data to users, the proposed technique gives the user the option to acquire information from any backup server in order to achieve reliability. The decryption procedure is then carried out in response to the user's request. Experiments were done to demonstrate the applicability of the proposed frameworks, and performance indicators were compared to those utilized by other researchers. Based on this study, a framework is developed, that guarantees authentication and lays the way for safe data access, with better performance and fewer complications than the previous efforts.

Teacher performance is an important part of achieving the goals of an educational institution. The good or bad of an educational institution or school can also be seen from the level of teacher performance. To avoid the bad side of teacher performance, a comfortable work environment, the right leadership style and support from the family are needed so that performance can be more optimal. This research intends to analyze the performance of teachers in PAUD in Cengkareng District, West Jakarta, which is affected by the work environment, leadership style and family support. Questionnaire data as primary data and school IKP and EKI documents as secondary data. There were 22 respondents in this research who were sampled. Multiple linear regression analysis as data analysis and t-test as a hypothesis test were all processed through SPSS version 26. The results of this research describe that performance is not partially affected by the work environment. Meanwhile performance is significantly affected positively by leadership style. Furthermore, performance is significantly positively affected by family support. Other test results, performance is significantly positively affected by the work environment, leadership style and family support simultaneously.

In recent days, computing and communication environments are extensively more difficult and disorganized than classically distributed systems over the internet, lacking any centralized organization or hierarchical control. In such case the emerging technology peer to peer overlay network is the answerable one. The peer to peer networks will provide a good layer for creating a data sharing, content delivery and optimal routing in many applications. Structured peer to peer network has a fixed structure that will be formed as a fixed topology. If any one of the nodes leaves or enters in the network, topology may vary. In such case, it will lead to load failure, link failure and resilience. a new architecture namely Distributed Hashing distributed grouping management (DHDGM) is proposed. The proposed DHDGM model uses the secure group architecture model those are processed vertically for the selection of group header. The resurces are shared between the group headers for the detection of the intruders. With the distributed grop management of the data between the network group data is transmitted in the P2P network. The simulation analysis of the proposed DHDGM model exhibist the ~4% - 7% reduced delay and packet drop rate compared with the existing ATAR and RSPP model.

Purpose: This research is conducted to examine the influence of ideal self-congruence on customer love and loyalty to two luxury brands. Theoretical Framework: Luxury brands have three dimensions, namely functional, experiential, and symbolic. A brand is said to be luxurious if it has some characteristics such as high quality, high price, sensuality, beauty, exclusivity, historicity, and uniqueness. Customer loyalty to brand is a crucial strategy choice for companies struggling to maintain business continuity. The organizations believes that brand loyalty can provide benefits for organization. Brand love is one of the determinants of brand loyalty. The concept of love developed in the context of interpersonal relationships. Design/Methodology/Approach: Sample random sampling technique used as sampling method in this study, this research collected 214 data through self-administrative survey from respondents of two luxury handbag brands in Indonesia. Analysis method in this research using Structural Equation Modelling (SEM). Findings: There are significant relationships between ideal self-congruence and customer love to brand, between ideal self-congruence and customer loyalty to brand, and between customer love and customer loyalty to brand. Research/Practical/Social Implications: On the theoretical level, this research contributes to a better understanding of how to create customer loyalty to brand through tracking the self-congruence construct and the customer love to brand. On the managerial level, this research provides a very useful actionable guidance to loyalty program managers on how to create luxury brand which incorporates customer ideal self-congruence and simultaneously arises a strong emotional bonding to brand. Originality/Value: The contemporary interest in customer loyalty to brand has resulted in a variety research of it conducted in many areas. Our investigation indicates that there are a few researches which address the relationship between ideal self-congruence, brand love, and customer loyalty to luxury brands.

The increased Internet utilization leads to emerging group-basedapplications such as military, healthcare, online collaboration, video conferencing and so. However, in the group-oriented application resources are secured through a constraint network. The promising multi-cast communication group-oriented communication model exhibits reduced bandwidth with the different decentralized group key management such as the decentralized group key framework. In this paper, proposed a Multicast Polynomial Key Distribution Scheme (MPKD)model with acentralized and decentralized key management framework. The proposed MPKD model comprises of the three process such as generation of key, distribution of key and refreshment of key. The proposed MPKD mode uses the logical key tree structure with the computation of the polynomial in the key generation process. The performance analysis is based on the structure protocol with the key distribution in the centralized framework model. The performance of the proposed MPKD model is comparatively examined with the conventional OFT, SKD and MUKD model. The analysis of the results expressed that proposed model ~2% - 4% reduces the communication and storage cost. The storage cost of the existing model exhibits the value of maximal 63 but the proposed MPKD model achieves 34 for the user count of 32. Similarly, the communication and storage cost is minimal for the unicast and multicast communication.
