Problems solved by technology
Information systems in the financial field have very high requirements for the confidentiality of transmitted data information. If the transmitted data information is leaked, it will pose a serious threat to the security of the entire financial field information system.
[0003] At present, the communication at the information system interface is mainly based on plaintext transmission, and the encryption method used in a small number of encrypted transmissions is also very simple, which is easy to crack, resulting in poor data transmission security.

The invention relates to a business data processing method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring a financial service instruction; based on a first system public key generated by a data receiver, performing encryption processing on the random key and the first current timestamp to obtain a digital envelope; performing digital signature processing on the financial service instruction, the random key and the first current timestamp based on a second system private key generated by a local machine to obtain a first data abstract; based on the random key, performing encryption processing on the financial service instruction to obtain encrypted data; and packaging the digital envelope, the first data abstract and the encrypted data into message data, and initiating a service request to a data receiver based on the message data. By adopting the method, the security of the financial service instruction in the transmission process can be greatly improved.
Description
technical field [0001] The present application relates to the technical field of financial security, in particular to a business data processing method, device, computer equipment, storage medium and computer program product. Background technique [0002] With the continuous development of computer network technology, in recent years, various unknown network security threats have emerged one after another, and network security incidents have occurred frequently. Among them, the information system interface is a crucial link in the network transmission process, and the message data communicated by the interface is easy to be illegally monitored, intercepted, tampered with or forged by attackers. Information systems in the financial field have very high requirements for the confidentiality of transmitted data information. If the transmitted data information is leaked, it will pose a serious threat to the security of the entire financial field information system. [0003] At p...
