Protection and security of Business process outsourcing in the cloud computing space (using a new digital signature solution, BLS)

In cloud computing, every resource is provided and delivered to the user as a service. This means that cloud computing is long-term computing that makes technology more and more successful. It is very easy and convenient to use and perform calculations because a user only needs a web browser and experience working with cloud computing. When it comes to data security and privacy, many challenges and issues arise for hackers. Researchers suggest that cloud computing security is not ۱۰۰% secure because information can be leaked at any level of the cloud and information can be leaked. Currently, protecting the functioning of the cloud on the Internet is a big challenge, and in the meantime, information security and maintaining user privacy in the cloud space are very necessary and critical. Issues such as data privacy, access control, encryption, identity management, and intrusion detection are among the important security challenges that are considered in cloud computing. Also, with the emergence of new technologies such as the Internet of Things and the expansion of further communications, new security challenges are expected to arise in this area in the future. Therefore, research in the field of identifying and resolving these challenges and providing appropriate and efficient solutions to protect users' vital information is of great importance. In this research, the model proposed is that when a user stores information and data in the cloud, he encrypts them and uses digital signature generation (BLS) to inspect the data to ensure security.
