Problems solved by technology
[0003] Disadvantage 1: KLD uses short-distance communication to inject the key, and the plaintext of the key is exposed to the transmission process of the communication medium without protection, and the data content is easily obtained by various monitoring devices, resulting in the leakage of sensitive information
[0004] Disadvantage 2: The key is manually input directly at the POS terminal, so that the key is carried out of the safe environment for use, and there are certain security risks in management, which may easily cause leakage of sensitive information

Embodiment Construction
[0055] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0056] In the present invention, all confidential information that should not be obtained by non-owners is collectively referred to as sensitive information. In the field of financial POS, sensitive information includes and is not limited to various keys used for financial transactions, bank card passwords (PINs) held by cardholders, and encryption technology-related keys used by POS manufacturers to achieve POS security. In order to facilitate the description of the mechanism of the present invention, a typical financial POS key download case is used for illustration below. But the present invention is not limited to the financial POS key download, and can be applied to any line transmission safety protection measures for sensitive inform...

The invention discloses a sensitive information transmission method which is used for transmitting sensitive information from a source terminal to a destination terminal, wherein the sensitive information is stored at the source terminal. The sensitive information transmission method includes the following steps that S1, an RSA private key and an RSA public key are stored at the source terminal and the destination terminal respectively; S2, the source terminal is subjected to legal verification by aid of the RSA private key and the RSA public key; S3, if the source terminal is legal, the destination terminal sends a request of to the source terminal for downloading the sensitive information, and the source terminal encrypts the sensitive information and sends the encrypted sensitive information to the destination terminal. The method fully uses the asymmetrical character of the RSA public key and the private key, and when the source terminal is verified to be legal, the sensitive information is encrypted and is transmitted to the destination terminal from the source terminal so that the download problem of the initial key of symmetrical keys in the field of information safety is solved, the key transmission in the form of plaintext is avoided, and the management is convenient. The invention simultaneously discloses a sensitive information transmission system.
Description
technical field [0001] The invention relates to the technical fields of information security and encryption, especially a transmission method and system for sensitive information. Background technique [0002] In the traditional financial POS initial key download method, usually in the safe environment of the bank, the initial key (sensitive information) is downloaded from the key download device (Key Load Device, KLD) using short-distance communication (RS- 232, etc.) to the POS terminal; or the full-time personnel directly manually input the initial key on the POS terminal. There are following defects in the above-mentioned way: [0003] Disadvantage 1: KLD uses short-distance communication to inject the key, and the plaintext of the key is exposed in the transmission process of the communication medium without protection, and the data content is easily obtained by various monitoring devices, resulting in the leakage of sensitive information. [0004] Disadvantage 2: The...
