Hybrid cryptographic algorithm

The traditional approach towards information security was to use a single encryption algorithm or any well-known cryptographic algorithm. In this paper, a combined encryption algorithm is proposed. That is, the algorithm security is greatly improved through researching and improving some data encryption algorithms, and arranging encryption algorithm in some predefined order. First, write an initial encryption algorithm, second, add in the famous AES algorithm, and then RSA algorithm. Using this hybrid algorithm, the user’s information is gradually encrypted, and the algorithm security is greatly enhanced.
