Data Security Scheme for a Trusted Third Party Platform Based on RSA One-time Key

In recent years, the possibility that cloud data is accessed illegally and the key is cracked in the process of storage is becoming increasingly. The paper proposes a data security scheme of a trusted third party platform based on RSA one-time pad encryption technology. It can use RSA one-time pad encryption technology to realize the function that encrypt the data in security. Then it manages the one-time key generation by the trusted third party platform. Finally, the simulation experiment detected the data security by using the MD5 algorithm and compared the digital fingerprint generated by the data before being attacked and after being attacked. The experimental results show that this scheme increases the workload of the key cracking, and reducing the probability of key being cracked and data being accessed illegally.
