Method for Realizing User Data Security Migration Based on Voice Channel

Abstract

The invention discloses a method for realizing safe migration of user data based on a voice channel. A cryptographic system combining symmetric cipher and asymmetric cipher is deployed on a trusted terminal of a secure telephone communication network. Utilize the characteristics of fast encryption and decryption speed, high computing efficiency, and less resource occupation of symmetric ciphers to complete the confidentiality protection of user information; use asymmetric ciphers to calculate the difficulty of discrete logarithms in finite fields to realize the identity authentication of both parties in communication, and at the same time With the help of the complex characteristics of the elliptic curve algorithm, the shared factor of the two parties in the communication is obtained through the point multiplication of the temporary public and private keys, and a one-time secret service data protection key is generated to ensure the forward security of user data; finally, the hash algorithm is used respectively The calculation determinism of the random sequence and the uncertainty of the random sequence solve the integrity protection of the user data during transmission and the anti-replayability 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...

AI Technical Summary

Problems solved by technology

In the field of telephone communication that requires high security, the user data of fixed-line terminals is relatively small, but there is a need for long-distance transmission, and the security requirements in the process are extremely high. Peripherals such as Bluetooth or WIFI or due to distance reasons, or are unavailable due to security risks
