A Hybrid Model for Cloud Data Security Using ECC-DES

An online data storage and retrieval system known as a cloud computing environment makes it easier for users to access data from virtually anywhere at any time. However, according to the CIA triad, data kept on the cloud is vulnerable to data breaches. Data integrity and authentication can be compromised since end users and third parties are both permitted access to the data. With the help of cryptographic algorithms like elliptic curve cryptography (ECC), numerous methods and protocols have been developed to ensure the security and integrity of data. A popular symmetric key block cypher method is the data encryption standard (DES). Up until it was proven unsafe, the security of DES was a sensitive and resolved topic. In this research, we present a method for protecting data transmission among users in cloud computing that, when combined with ECC, can address the security issue with DES. We present a hybrid approach that combines two cryptographic methods. We propose a solution to reduce the key size issue. In comparison to existing encryption systems, our system ensures data confidentiality and authentication integrity. By retaining more space, our plan reduces computational complexity.
