Safety intelligent hardware, and protection method and system of user data of intelligent terminal

Abstract

The invention discloses safety intelligent hardware, and a protection method and system of user data of an intelligent terminal. The safety intelligent hardware comprises a cryptographic algorithm module, a safety data storage module, a wireless communication module, and a safety software storage unit. The safety intelligent hardware can carry out wireless communication with the intelligent terminal, thereby providing safety protection for the user data in the intelligent terminal; and thus the user secret data in the safety intelligent hardware can be outputted and inputted safely. The provided safety intelligent hardware, and the protection method and system of user data of an intelligent terminal can be applied to the technical field of information safety.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a method and system for protecting intelligent security hardware, intelligent terminal user data. Background technique [0002] With the continuous development of information technology, smart terminals represented by smart phones are used more and more in people's daily life and work. Using smart terminals makes it easy for people to acquire, store, process and process information. Interaction greatly facilitates people's daily life and work. More common smart terminal products, such as mobile smart terminals, vehicle smart terminals, IoT smart terminals, smart home appliances and wearable smart devices. However, since many smart terminals have the function of connecting to the network, once a smart terminal is maliciously attacked, it is likely to cause leakage of user data, and even cause great losses to the user's property and other aspects. Therefore, while t...

Problems solved by technology

The current main defects of the external key encryption technology include: 1. It does not provide the safe export and import function of the key in the external key. The key can only exist in a certain external key. Once the external key is lost or damaged, the encrypted The data cannot be decrypted, which seriously affects the usability of the data; 2. The function of the external key is single, and the various cryptographic application systems are not compatible. The ciphertext or digital signature of one cryptographic application system cannot be decrypted or verified in another system, and the user Each password application system needs to apply for an external key, which not only increases the purchase cost for the user, but also causes inconvenience in the management and portability of multiple external keys
