Secure Data Storage based on Integrated Encryption Technology in Cloud Environment

The development of cloud computing poses data security challenges to cloud storage services, and traditional encrypted storage mechanisms have shortcomings. This article proposes an integrated secure data storage system framework that uses RSA algorithm to establish encryption mechanism. Through data preprocessing and pseudocode generation, encryption and decryption are performed using modular exponentiation to ensure secure storage of data. It was found that the RSA algorithm proposed in this article only takes 52.12 seconds to encrypt 60000 pieces of data. With the continuous increase of plaintext/bytes, the RSA algorithm ciphertext always remains at 15 bytes. When the plaintext length is 250 bytes, the RSA algorithm takes 25 seconds to access and can access the entire plaintext. This system has improved the security factor of data transmission. The RSA algorithm has advantages in encryption performance, ciphertext length, access time consumption, and plaintext access security, which can effectively ensure the secure storage of data and meet the data security requirements in cloud environments.
