Encryption method of call handling strategy

Abstract

An encryption method of a call handling strategy comprises the following steps: a management device generates a public key and a private key by using an asymmetric encryption algorithm, and provides the public key to a control device on a communication service server; the management device encrypts a fraud phone call processing strategy through a public key; wherein the strategy comprises suspicious fraud number data and suspicious fraud number segment data, the suspicious fraud number data is a suspicious fraud number encrypted by using a public key, the suspicious fraud number segment data is composed of a suspicious fraud number segment length and an encrypted suspicious fraud number segment, and then synchronizing a call processing strategy to the control device; and the control deviceextracts the number from the call triggered to the service server, matches the extracted number with the call processing strategy, and when the extracted number is consistent with the call processingstrategy, indicates that the call is a suspicious fraud call and processes the call. The invention belongs to the technical field of information, and can ensure the safety of suspicious fraud numbersand number segment data in a call processing strategy and prevent sensitive data leakage.

Description

technical field [0001] The invention relates to an encryption method for a call handling policy, belonging to the field of information technology. Background technique [0002] Mobile communication technology facilitates people's life and work, and has made an indelible contribution to the development of social economy. However, where there is light, there must be darkness. In recent years, malicious acts such as fraudulent calls have been banned repeatedly. In order to effectively combat fraudulent calls, it is necessary to form a communication protection network against fraudulent calls. [0003] In the call handling of fraudulent calls, the calling number is usually matched with the suspected fraudulent number and number segment. However, from the perspective of security, the management side does not want the call control side to be able to obtain the list of suspected fraudulent numbers. Therefore, how to ensure the security of suspicious fraudulent numbers and number s...

[0003] In the call handling of fraudulent calls, the calling number is usually matched with the suspected fraudulent number and number segment. However, from the perspective of security, the management side does not want the call control side to be able to obtain the list of suspected fraudulent numbers. Therefore, how to ensure the security of suspicious fraudulent numbers and number segment data in fraudulent call handling strategies and prevent sensitive data leakage has become a technical problem that technicians urgently need to solve
