WebJan 1, 2024 · After studying all of the trending hybrid cryptographic models, we came up with the conclusion that data security is the most considerable topic related to cloud computing technology. Webcryptography is based on the following empirically observed fact (here written as if it were carved in stone): Multiplying two integers is easy, but finding a nontrivial factor of an integer is hard. In other words, integer multiplication is in practice a “one-way function.” If a number is large, it’s essentially impossible to factor it. 11 how to spell trick or treatingWebThis section will described briefly, all the terms used in cryptography model.
