New hybrid encryption algorithm for cloud computing security using chaotic system and mCrypton-salsa20 algorithms.

Cloud computing is among the technologies that have become popular in recent times, due to the increasing demand for their use by individuals, companies and organizations. It offers its resources as an online service upon demand by its users. In order to enhance the trust between the cloud and its users, attention must be paid to addressing the issues that the cloud suffers from, the most outstanding of those are problems relating to the safety and privacy of users' data on the cloud. Encryption is considered one of the successful and efficient ways to raise the security of data kept on the cloud by converting it into data that is incomprehensible to unauthorized persons. In our research paper, we will present a method that provides security and privacy for data stored on the cloud, and this method consists of a combination of two lightweight algorithms (mCrypton and salsa20) to form a new lightweight hybrid algorithm based on the mCrypton algorithm, where stages were added to it and other modifications. Additionally, chaos has been added to generate encryption keys. [ABSTRACT FROM AUTHOR]
