Hybrid Encryption of Cloud Processing With IOT Devices Using DNA And RSA Cryptography

The research paper titled "Hybrid Data Encryption as well as Decryption Using Hybrid RSA and DNA" develops a hybrid cryptosystem by combining the usefulness of such an asymmetric-key (public-key) cryptosystem with the efficacy of a symmetric-key (private-key) cryptosystem. These two types of cryptosystems use different types of keys. The method addresses concerns regarding the users' right to privacy, authentication, and accuracy by utilizing a data encryption process that is secure in both directions. Both the process of encrypting data and the process of decrypting data, which are both utilized by the system, are two different encryption methods. It has been suggested that a hybrid encryption algorithm, which combines DNA and RSA, be used for file encryption in order to address the issues with efficiency and security. The results of the testing show that the RSA and DNA hybrid encryption algorithm is suitable for use. In this particular research project's hybrid encryption and decoding for cloud processing with IOT devices, the DNA and RSA algorithms were used

ENCRYPTION ALGORITHMS FOR DATABASES

For most cases, people use an ecrypted mode when sending personal information to a server, via an electronic form. Whenever shopping is done online, the browser uses cryptographic methods to send to the server the credit card number and private information. Thanks to the surprising development of the Internet, and not to the structural models (OSI and TCP/IP) this technology is based on, the electronic commerce requires quality, security, reliability and, above all, the possibility of implementing all such concepts. It is interesting that none of the widely used cryptographic systems is mathematically demonstrated to be safe. As a matter of fact, the entire technology of cryptography is based on mathematical problems that are still unanswered to.Looking at the above, the study of the cryptographic and security methods, as well as finding strong crypto-systems is still a pivotal issue.encryption algorithms; database security; crypto-graphically; cipher

A Combination of Vigenere Cipher and Advanced Encryption Standard for Image Security

In an era where digital information security is paramount, this research addresses the pressing need for robust encryption methods. We propose a novel approach that combines the Vigenere Cipher and the Advanced Encryption Standard (AES) for secure digital image transmission. Our study recognizes the research gap in secure image transmission methods and aims to bridge it with a powerful encryption solution.
