And determining the effectiveness of the information interaction of the block chain financial data by using a formula, thereby ensuring the operation reliability of the block chain data storage module. The financial data information interaction capacity is greatly improved.
In the above embodiment, the encryption module is an improved Blowfish encryption algorithm module, and the improved Blowfish encryption algorithm module includes an encryption unit, a block link point, and a decryption unit, where an output end of the encryption unit is connected to an input end of a block chain node, and an output end of the block chain node is connected to an input end of the decryption unit.
In the above embodiment, the encryption unit is provided with an early warning function and a clear function, the encryption unit encrypts the data information in the transmission process through a Blowfish encryption algorithm in the encryption process, when the encrypted data information meets risk data information, the early warning function is automatically started to prompt that risk occurs in the transmission process, when the early warning level reaches the set highest level, the clear function is automatically started, the high-risk financial data information in the transmission process is cleared, and the financial data information before clearing is returned in the original way.
In a specific embodiment, Blowfish is an algorithm by 64-bit grouping whose key can change its length, and this is a symmetric encryption algorithm that can quickly encrypt a 64-bit length string. The Blowfish encryption algorithm is capable of fast encryption and decryption and has a variable key length, which is well known for these characteristics. The whole operation process needs to be divided into two steps to encrypt and decrypt data by using a Blowfish encryption algorithm: the first step of the operation is to pre-process the key of the encryption algorithm, in the design of the Blowfish encryption algorithm, it provides the source keys-pbox and sbox of the Blowfish algorithm, the source keys-pbox and sbox provided are fixed, each user uses the same set of source keys-pbox and sbox.
Therefore, if it is desired to encrypt data, as shown in fig. 3, it is necessary to prepare an encryption key, and use this key in combination with the source keys-pbox and sbox to generate the sub-keys key _ pbox and key _ sbox. The second step is to encrypt the data by key _ pbox and key _ sbox. The encryption flow of the Blowfish encryption algorithm is shown in fig. 3. Since Blowfish is a symmetric encryption algorithm, the sub-keys key _ pbox and key _ sbox also need to be generated through key preprocessing during decryption, except that the order of encryption and decryption by using the sub-keys is reversed. In the Blowfish encryption algorithm, the length of the encryption key is uncertain, and the length of the encryption key can be changed, so that great convenience is brought to a user in designing the key, and great hidden danger is brought to data security. Since the Blowfish encryption algorithm is at the core of encryption and decryption in key selection and confidentiality, improvements in the selection and confidentiality of Blowfish encryption algorithm keys are needed.
As shown in fig. 4, user a needs to prepare the public keys of Blowfish encryption algorithm, MD5 algorithm, and RSA encryption algorithm of user B to send data message M to user B, and prepare three tools to complete the following work. A user A sending end needs to encrypt an electronic file by using a Blowfish encryption algorithm to obtain a document ciphertext; encrypting the secret key of the Blowfish encryption algorithm through the RSA encryption algorithm public key received by the public network to obtain a Blowfish secret key ciphertext; and finally, the digital signature is carried out on the official document ciphertext through the MD5 algorithm, so that whether the data transmission is complete can be verified, and the encrypted official document ciphertext can only be obtained even if the MD5 algorithm is cracked violently, still needs to be cracked, and has great safety.
In the above embodiment, as shown in fig. 5, the operation method of the decryption unit is as follows:
decrypting the signature block by using the MD5 algorithm public key, comparing the ciphertext of the official document by using the hash function digest, if the sources are the same and no loophole is found, considering the file as complete without resending, if the MD5 algorithm public key can not realize data decryption, starting the RSA decryption algorithm to decrypt the data information of the file, and then outputting the secret key of the Blowfish encryption algorithm; and finally, decrypting the document ciphertext through the key of the Blowfish encryption algorithm, and outputting the decrypted electronic file M.
