This research aimed to identify the determinants of technology usage among SME employees in the North Kivu Province of the Democratic Republic of Congo. We based our model on the Technology Acceptance Model. In addition to perceived usefulness and ease of use, the proposed model includes relative advantage as a predictor of technology usage. This study used the PLS-SEM method to test the proposed hypotheses from 247 responses. The results confirmed the hypotheses. The research findings demonstrate a positive relationship between perceived usefulness and use, perceived ease of use and use, and relative advantages and use of new technologies. Congolese SME managers can rely on these findings to highlight these key determinants in promoting technology usage among SMEs in a country where technology usage by businesses remains low. Keywords: Perceived ease of use, Perceived usefulness, Relative advantages, SI adoption, Technology.

“…Cryptographic Scheme [49,50]. From the trend of the encryption time from Table 1, it could be concluded that encryption times for NCS and EHS are not dependent on data size but the size of the key while the encryption times for Salsa20, Chacha20, and ERSA are influenced by data size.…”

The cloud is becoming a hub for sensitive data as technology develops, making it increasingly vulnerable, especially as more people get access. Data should be protected and secured since a larger number of individuals utilize the cloud for a variety of purposes. Confidentiality and privacy of data is attained through the use of cryptographic techniques. While each cryptographic method completes the same objective, they all employ different amounts of CPU, memory, throughput, encryption, and decryption times. It is necessary to contrast the various possibilities in order to choose the optimal cryptographic algorithm. An integrated data size of 5n*102 (KB (∈ 1,2,4,10,20,40) is evaluated in this article. Performance metrics including run time, memory use, and throughput time were used in the comparison. To determine the effectiveness of each cryptographic technique, the data sizes were run fifteen (15) times, and the mean simulation results were then reported. In terms of run time trend, NCS is superior to the other algorithms according to Friedman’s test and Bonferroni’s Post Hoc test.

“…The advantages of the RC4 algorithm are that the algorithm is effective, simple, and well-suited for program implementation, which are distinguished by their implementation speed, do not require a great amount of storage space, and has less complexity [1], and it is frequently used in protocols and standards such as Skype, WPA, WEP, and SSL/TLS [14].…”

“…Rivest cipher 4 (RC4) is a significant cipher of the stream that could be found in a wide range of protocols of the internet, including Skype, secure socket layer, transport layer security (SSL/TLS), wireless protected access (WPA), and wired equivalent privacy (WEP) [1], [2]. The speed and clarity of the RC4 algorithm's significant operators have been over such a substantial field of applications; the efficient implementation of both hardware and software has been extremely easy to develop [3].…”

“…In comparison to many other encryption algorithms, RC4 is fast and small. The RC4 algorithm encryption procedure was divided into two parts: (1) an assessment of the RC4's initialization, with an emphasis on the key scheduling algorithm's (KSA) initialization, and (2) an evaluation of the keystream generating output, with an emphasis on the pseudo-random generation algorithm (PRGA) round-running process and internal status [4]. Random numbers play an important role in cryptographic processes.…”

Digital technologies grow more rapidly; information security threats are becoming increasingly dangerous. Advanced and various cyber-attacks and security threats, like targeted emails, and information exploitation, pose a critical threat that basically undermines our trust in the digital society. Rivest cipher 4 (RC4) algorithm is a significant cipher of a stream that could be utilized with protocols of the internet, the advantage of the RC4 algorithm is that it is simple and effective. There are several weak, especially after the pseudo-random generation algorithm (PRGA), PRGA's initially 256 rounds (the amount of the RC4 permutation). Several modified RC4 studies have been published thus far, however, they all face either standard privacy or achievement evaluation issues. This paper proposes a new RC4 algorithm that is based on the user's retina (RC4-Retina), which has solved both of these weak points it was indicated in the standard RC4 algorithm. The novelty of retina key scheduling algorithm (RKSA), which is generated by relying on the user's retina of the algorithm will modify the matrix of permutation used to configure the keys. The efficiency of the improved algorithm was measured by depending on the average security of ciphertext of different keys and different messages, results were good compared to the standard algorithm.
