Design and Implementation of an Improved Cryptographic Algorithm using UNICODE and Universal Colors
Abstract: AbstractA new cryptography algorithm based on Unicode and Universal colors is proposed to preserve the confidentiality of the data. The use of Unicode as encoding scheme provides support to a very large range of characters. The colors are used to obtain a large key domain to avoid cryptanalyst attacks like brute-force and dictionary attacks. The concept is based on the symmetric key cryptography that supports the use of a single …

A Practical Approach for Privacy Preserving in Cloud Computing Using Fully Homomorphic Encryption Scheme BFV and CKKS
Abstract: Cloud computing is a new type of computing architecture whereby data may be accessed over the Internet along with other services linked to its scalable data centers in the cloud. The risk associated with computing is increased since it provides essential services that are typically provided to any third party, making it more difficult to enable data security, privacy, confidentiality, integrity, and authentication. To reduce security risks, most users choose …

End-to-End Data Security for Multi-Tenant Cloud Environment
Abstract: AbstractThis paper details the construction of a functional model that ensures data kept encrypted; while being processed in a multi-tenanted cloud environment. This can be done using homomorphic encryption only though the approach lacks in ability to search large databases. In a multi-tenant cloud environment, data is stored on several distinct data centers. As the request is encrypted, the server can't come up with exact match, so it would probably …

Homomorphic Encryption Property Algorithms
Abstract: The demand for privacy of digital data increased over the last decade. The new invention in cryptography world is Homomorphic Encryption (HE). HE enables operation on cipher text without knowing the plaintext and private key. When receiver decrypts the result of any operation, it is the same as if the receiver carried out the calculation on the plain text. HE has some specific property. There are two properties in homomorphic …

Data Privacy in AI: Securing the Sensitive Information Through Homomorphic Encryption
Abstract: Artificial intelligence (AI) technology increasingly relies on sensitive user data, particularly finance and healthcare. While legacy encryption technologies safeguard data in transit and at rest, they are of no use when data must be decrypted to be processed. This is a bleak privacy threat, particularly in AI applications that call for constant processing of data. The objective of this study is to apply homomorphic encryption, a feature in which operations …

The Evolution of Ransomware: In-Depth Analysis of Threat Development and Modern Defense Mechanisms
Abstract: Ransomware is the most severe of all cybersecurity threats the contemporary digital world is confronted with. It is a form of malware that encrypts a victim's information and requests ransom, usually in cryptocurrency, for its decryption. From its first appearance in the late 1980s, ransomware grew from simple malware into very advanced and targeted attacks that can be used to bring down entire organizations, businesses and critical infrastructure. This study …

Data Transmission Using Laser
Abstract: This paper proposes a model to transmit data using raspberry pi, Laser light and Light Detecting Resistance(LDR) sensor. The model takes the input as a file and then the data is encoded into binary, then encrypted . Now the encrypted data is transmitted to the receiver side using a Laser which is detected by the LDR sensor. After that the received data is decrypted and decoded into the required file. …

An Overview to Enhance Visual Cryptography Techniques
Abstract: A unique type of cryptographic method called "visual cryptography" allows for decryption to be carried out using only the human eye. Generally speaking, for some crucial security, in modern society, processing and protecting information from attacks is becoming a very important aspect for people. Researchers are developing new ways to protect information from unwanted intrusion. Numerous encryption methods have been discovered, with many more yet to be discovered. Visual ciphers …
