Method and device for secure storage and retrieval of sensitive data in operation and maintenance system

Abstract

The invention provides a method and device for secure storage and retrieval of sensitive data in an operation and maintenance system. The method mainly comprises steps as follows: sensitive data configuration is loaded; the sensitive data in import data are simultaneously subjected to scrambling operation and encryption operation according to the sensitive data configuration, so that scrambled data and encrypted data are generated and stored respectively; input data are received, sensitive data configuration corresponding to the sensitive data in the input data is determined, the sensitive data in the input data are simultaneously subjected to scrambling operation and encryption operation according to the corresponding sensitive data configuration to generate scrambled data and encrypted data respectively; the encryption data are used to replace the sensitive data in the input data to generate translated input data, then the translated input data are used for retrieval, and the scrambled data are used for verifying a retrieval result. The invention further provides a corresponding device. The method and device have the advantages of safety, function completeness, high utilization rate, low cost, good applicability and high efficiency.

Description

technical field [0001] The invention relates to an operation and maintenance system, in particular to a method for safely storing and retrieving sensitive data in the operation and maintenance system. Background technique [0002] Operation and maintenance support system (referred to as operation and maintenance system): refers to the computer production business system (referred to as business system), which monitors and analyzes the business system, provides statistics and summary of system operation status, early fault alarm, rapid fault diagnosis and An auxiliary system for important functions such as fault location, transaction tracking and query, so as to support the production business system, ensure its normal operation, and continuously improve the operation quality. [0003] Sensitive data: refers to important user data such as user numbers, mobile phone numbers, email addresses, bank card numbers, and credit card numbers that come from the production business syst...

AI Technical Summary

Problems solved by technology

As for the operation and maintenance system, most of its users are ordinary operation and maintenance personnel, and they are far from reaching this level of authorization.

[0010] In order to deal with this situation, there are generally the following practical methods at present: (1) the operation and maintenance system does not store sensitive data, and does not provide corresponding functions such as query and diagnosis and positioning; (2) to increase the complexity of the operation and maintenance system, the monitoring data Data sources and processed data are classified and processed with multi-level permissions to limit access to sensitive data and only allow a small number of authorized personnel to use

Method (1) reduces the functions of the operation and maintenance system, while method (2) not only greatly increases the development cost of the operation and maintenance system, but also greatly increases the use of the operation and maintenance system due to the complex control at all levels and only a small number of personnel are allowed to use it. and operating costs, and is not conducive to various changes in the project, such as changing servers or business systems, adding or subtracting servers or business systems, expanding business functions, etc.
