Security Encryption Control Method of Trading Platform Information Network Based on Blockchain Technology

The conventional encryption control method for information network security of trading platform is mainly based on complex ciphertext. Although the information security is high, it adds a burden to decryption. Therefore, the security encryption control method of trading platform information network based on blockchain technology is designed. Authenticate the information access identity of the trading platform, verify the identity of each visitor, generate an identifier from the verified identity information, and distribute the platform key, so that only visitors who have the key can make a second access, thus ensuring the security of the trading platform information. Based on blockchain technology, the intelligent contract for information network security encryption control of trading platform is deployed, the preset encryption contract terms are executed by computer programming, and the integrity of information network encryption of trading platform is ensured by decentralization, transparency, non-breach, automation, non-tampering and anonymity. The comparison experiment shows that the encryption control effect of this method is better and can be applied to real life.
