Abstract

The embodiment of the invention discloses a data migration method and system. The method comprises the following steps: a migration preparation stage: a source encryption machine sends a key encryption packet generated by a first administrator lock to a target encryption machine, and the target encryption machine sends the key encryption packet to a second administrator lock; When a synchronization request is received, the source encryption machine obtains a first key synchronization packet from the first administrator lock, and the target encryption machine obtains a second key synchronization packet from the second administrator lock; In the data migration stage, the source encryption machine processes the original data ciphertext by using a source service key and encrypts the original data ciphertext by using a temporary key obtained based on a first key synchronization packet to obtain an original data temporary ciphertext; And the target encryption machine processes the original data temporary ciphertext by using the temporary key obtained based on the second key synchronization packet, and encrypts the original data temporary ciphertext by using the target service key. According to the embodiment of the invention, data security migration between encryption machines can be realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data security, and in particular, to a data migration method and system. Background technique [0002] Normally, in order to prevent the leakage of password-type data, the user's password is generally not saved in plain text, nor is the reversible ciphertext of the password saved, but the irreversible HMAC (key-related hash operation message authentication of the password) Code, Hash-based Message Authentication Code) value is saved as password verification data. Furthermore, an encryption machine can also be used to encrypt multiple rounds of HMAC values ​​of the password and store them as password verification data. Multiple rounds of HMAC will make illegal users pay more computing power. Moreover, using an encryption machine to encrypt will hide multiple rounds of HMAC values, so that illegal users will not be able to compare the original text, which greatly increases the ...
