Abstract

The present invention provides a method and an apparatus for data processing. The method comprises: performing first comparison on a locally stored version number of a set of data with a remotely stored version number of the set of data; according to a positive result of the first comparison, reading data file, the data file containing the set of data and the version number of the set of data; performing second comparison on the locally stored version number with a version number of the set of data included in the data file; and accessing the set of data according to a positive result of the second comparison. The method and the apparatus for data processing can effectively improve secure access of security data.

Description

technical field [0001] The present invention relates generally to data security, and more particularly to a technique for preventing rollback attacks (rollback) on some secure data versions by remote attacks. Background technique [0002] Unless otherwise stated, the approaches described in this section are not antecedents to the claims listed above and are not admitted to be antecedents by their incorporation in this section. Data security generally refers to the protection of data, such as databases and / or data files, from destructive forces and unwanted actions by unauthorized users. For example, a remote attack targeting one or more computers looking for a weak point in the computer's security software or network to gain access to the computer or system is a malicious act. The main reasons for remote attacks are to illegally browse or obtain secure data, introduce viruses or other malware, and / or cause damage to the targeted computer or network. Various data security t...
