Virtual intelligent password key

Abstract

The invention discloses a virtual intelligent password key which is characterized by comprising security design and logic design. The security design comprises the working processes of generating a random number via a security plug-in, and dispersing a data encryption key via an algorithm; encrypting data or a file needing to be encrypted by combining with an encryption key to form a data ciphertext, and storing the random number and the data ciphertext by a terminal; and when in decryption, according to the random number and equipment information, performing inverse operation of a symmetric algorithm on the data ciphertext in combination with the data encryption key to acquire a decrypted original file. The logic design can be divided into the following modules of initialization, right control, equipment management, application management, container management, file management and password security service. The virtual intelligent password key is used as sensitivity data of a mobile terminal, so that secure storage is also important; the encryption key dynamically generated by multiple factors is used for performing encryption protection; even the user leaks the file of the password key, the other people cannot decrypt either, and the storage security is ensured.

Description

technical field [0001] The invention belongs to the technical field of cipher keys, and in particular relates to a virtual smart cipher key. Background technique [0002] In the current social background of the increasing popularity of the mobile Internet, smart phones have penetrated into all aspects of our lives, but the traditional smart password key needs hardware support and cannot be applied to the mobile terminal, so there are great limitations. The virtual smart password key is for It is developed and designed to solve the problem that mobile terminals cannot be inserted into hardware devices, and can be widely used in mobile online banking, CA applications, e-government, electronic signatures, secure emails, VPN access, and e-commerce. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of virtual intelligent password key which is simple in operation, low in cost, high in strength and good in stabilit...
