“…Additionally, it adapts to concerns regarding email privacy and user identification raised by hashed email approaches. Our comprehensive evaluation, spanning hash construction time comparison, avalanche testing, and attack resistance assessment, provides a holistic understanding of security concerns and validates the proposed enhancements [20]. The realworld applicability of our findings is significant, given the fundamental role of email communication in modern life.…”

Email security, particularly against phishing, spoofing, and distributed denial-of-service (DoS) attacks, is a pressing concern given the essential role email plays in accessing various online accounts. The study introduced a modified SHA-512 algorithm, implementing additional security layers including randomly generated salt and the Bcrypt algorithm. The modified SHA-512 was comprehensively evaluated on parameters like hash construction, computational efficiency, data integrity, collision resistance, and attack resistance. The results showed its avalanche percentage exceeded the 50% target, reaching 50.08%. Experimental hash-cracking failed to decode the hashes created by the modified algorithm, verifying its protective efficiency. The algorithm also successfully demonstrated data integrity and collision resistance. This indicates that the enhanced SHA-512 algorithm is an effective, more secure hashing method, particularly applicable to email addresses.

“…Creating a fast and high secure encryption algorithm requires to balance between speed and complexity due to the inverse relationship between them [10][11][12][13]. Increasing the security of any encryption algorithm requires increasing the degree of complexity through adding some additional processes, complex operations, increasing the number of rounds, and so on [14][15][16][17]. is will increase the encryption process time which leads to reduce the algorithm speed [18][19][20].…”

Providing security for transmitted data through the e-commerce environment requires using a fast and high secure encryption algorithm. Balancing between the speed and the security degree is a problem that many of the encryption algorithms suffer from. Increasing the security degree requires increasing the level of complexity which results in increasing encryption time. On the other hand, increasing the algorithm speed may reduce the complexity degree which affects the security level. This paper aims to design an encryption algorithm that balances time and complexity (speed and security). This is done by suggesting a security environment that depends on creating and providing an agent software to be settled into each customer device that manages the purchase and security process without customer interference. The suggested encryption algorithm is applied within this environment. Several modifications are performed on the AES encryption algorithm. The AES was chosen due to its performance (security and speed), which makes it suitable for encrypting transmitted data over the Internet. These modifications involve adding preprocessing steps (padding and zigzag), eliminating Sub Byte step, and reducing the number of rounds. The experimental results showed that the suggested algorithm provides more security and speed in the encryption and decryption process. The randomness degree has increased by 29.5%. The efficiency is increased because the encryption and decryption times are reduced, as is the CPU usage. The throughput for the suggested algorithm is increased by 10% for the encryption process and is increased by 9.3% for the decryption process.

“…The message to be embedded in the QR code is the name of the student to which the certificate belongs. A modified SHA-1 algorithm [26] was applied to create the hash value. After the hash value is created, the hash will be encrypted using modified blowfish algorithm [27] for added security during the transmission of data to the server.…”

A previous study has been conducted integrating modification on secure hash algorithm 1 (SHA-1) to document integrity verification of printed documents using quick response (QR) codes. However, encryption is warranted as data is transmitted in plaintext directly to the server to prevent hacking and ensuring not only data integrity but data security as well. A more secured document integrity verification using QR code was designed and developed by successfully incorporating a better hashing algorithm– modified SHA-1 and integrating a modern encryption algorithm–modified blowfish algorithm. By integrating both, data integrity and data confidentiality is assured as compared to previous research. The developed software was checked against user requirements to check the acceptability of the software. Error rate and accuracy were also checked to see how the software performed. Based on the testing conducted, it has been found that the document integrity verification software using QR code with the integration of modified SHA-1 hash and Modified Blowfish encryption was acceptable, accurate, and more secure.
