Method for realizing secure migration of user data based on voice channel

Abstract

The invention discloses a method for realizing safe migration of user data based on a voice channel, which comprises the following steps of: deploying a cryptosystem combining a symmetric password and an asymmetric password on a trusted terminal of a secret telephone communication network; confidentiality protection of the user information being completed by utilizing the characteristics of high encryption and decryption speed, high calculation efficiency and less resource occupation of the symmetric password; identity authentication of two communication parties being realized by utilizing calculation difficulty of discrete logarithms of asymmetric passwords in a finite field, and meanwhile, sharing factors of the two communication parties being obtained through point multiplication of temporary public and private keys by means of composite characteristics of an elliptic curve algorithm, so that a one-time pad service data protection key being generated, and forward security of user data is ensured; and finally, respectively utilizing the calculation determinacy of the hash algorithm and the uncertainty of the random sequence to solve the problems of integrity protection of the user data in the transmission process and the anti-replay performance of the cryptographic protocol.

Description

technical field

[0001] The invention relates to the technical field of data migration, in particular to a method for realizing safe migration of user data based on a voice channel. Background technique

[0002] In recent years, with the development of mobile communication technology, the dominance of fixed telephone in the traditional market has been continuously impacted. However, the broadband voice communication platform with the voice exchange server as the core breaks through the restrictions of the network firewall on VoIP technology. It is more in line with the development trend of the new generation network represented by IMS, and plays an irreplaceable role in the field of fixed telephone communication.

[0003] In order to meet the diverse needs of users, more and more services are integrated on broadband telephone terminals, such as short messages, memos, private calls, voice assistants, meeting schedules, etc. As an important carrier for storing user informatio...

Examples

Embodiment Construction

[0041] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] see Figure 1 to Figure 3 A method for implementing secure migration of user data based on a voice channel is applied to data transfer between two device terminals, including a request terminal, a transfer terminal and a broadband voice server, and includes the following steps:

[0043] Establish a connection: the requesting terminal and the transfer terminal use the signaling channel with the broadband voice server to establish a call connection;

[0044]Identity authentication request and verification: the requesting terminal uses the media channel in the call connection to send an identity authentication request to the transfer terminal, and the transfer terminal verifies the identity authentication request to realize the identity authentication and authentication of both parties;
