Hardware encryption protection method and system for cellphone data

Abstract

The invention discloses a hardware encryption protection method and system for cellphone data. The hardware encryption protection method includes utilizing ID (identity) of a cellphone, IMEI (international mobile equipment identity) numbers of an SIM (subscriber identity module), SNs (serial numbers) of a storage chip and name of a source file as dynamic parameters, calling a key generating module and an AES (advanced encryption standard) encrypting and decrypting module to generate Keys for encryption and decryption by being matched with logic calculation; calling a hardware encrypting module to encrypt the file or data for the source file. The key generating module, the AES encryption and decryption module and the encryption and decryption module operate file storage equipment through the storage chip, data encryption and decryption are completed, and the storage chip is welded on a circuit board of the cellphone and provided with an independent core processor. The hardware encryption protection technology for the cellphone data overcomes the defects of the prior art, is free of system resource occupation, has high performance, safety and reliability, and can effectively meet the encryption protection requirements on important files of people.

Description

technical field [0001] The invention is applied to the fields of mobile communication, information security and the like, and in particular relates to a mobile phone data hardware encryption method and system with high reliability and high security. Background technique [0002] Through investigation, there is no method for mobile phones to use hardware encryption chips for data protection in the market at present, and some files are encrypted and decrypted mainly through pure software applications. The usual way to achieve this is: set a security password (it can be a password or a pattern) for user login authentication; after passing the authentication, you can enter the private space, and in the private space you can specify files for encryption, or Encrypted files are decrypted here. But there are following two main deficiencies in this method: (1) the performance problem of encryption and decryption. Because of software encryption, full-text encryption is required for...

AI Technical Summary

Problems solved by technology

But there are following two main deficiencies in this method: (1) the performance problem of encryption and decryption

For a large number of pictures or videos, even partially encrypted, there are performance problems when the pictures need to be seen in real time

(2) Security issues

If the encryption requirements are relatively high, these methods will not meet the requirements
