Background
The vehicle insurance anti-fraud platform is a hardware platform for implementing the vehicle insurance business, and the data security of the vehicle insurance anti-fraud platform is a key factor for ensuring the normal operation of the vehicle insurance business. Data encryption is recognized as the only practical method for protecting data transmission security and the effective method for protecting the security of stored data, and is the most important defense line in the technology of data protection. Data encryption refers to the transformation of sensitive plaintext data into ciphertext data that is difficult to identify according to a particular cryptographic algorithm and cipher copper. When necessary, the ciphertext data may be restored to plaintext data, i.e., data decrypted, using a cryptographic algorithm and key corresponding to the encryption. By encrypting the data at the transmitting end and decrypting the received ciphertext data at the receiving end, the security of the data in the transmission process can be ensured. With the rapid development of information technology and network technology, the data security of the current vehicle insurance anti-fraud platform is seriously threatened.
