no. 1 approach

[0089] Next, the password security system for mobile devices according to the first embodiment of the present invention will be described.

[0090] image 3 is a configuration diagram of a cryptographic security system for mobile devices according to the first embodiment of the present invention.

[0091] like image 3 As shown, the password security system for mobile devices according to the first embodiment of the present invention includes a smart phone 400 and a wearable device 500 . Wherein, the smart phone 400 includes a TEEI area (TrustedExecutiveEnvironmentIntegration, trusted execution environment) 410 and an Android area 420 . In the first embodiment, the TEEI area 410 is equivalent to the aforementioned security device, the Android area 420 is equivalent to the aforementioned first mobile device, and the wearable device 500 is equivalent to the aforementioned second mobile device.

[0092] In the current technology, TEEI (Trusted ExecutionEnvironmentIntegration, ...

[0120] Figure 4 is a configuration diagram of a cryptographic security system for mobile devices according to the second embodiment of the present invention.

[0121] like Figure 4 As shown, the password security system for mobile devices according to the second embodiment of the present invention includes a smart phone 600 and a wearable device 700 . Wherein, the smart phone 600 includes a TEEI area (TrustedExecutiveEnvironmentIntegration, trusted execution environment) 610 and an Android area 620 . In the first embodiment, the TEEI area 610 is equivalent to the aforementioned security device, the Android area 620 is equivalent to the aforementioned first mobile device, and the wearable device 700 is equivalent to the aforementioned second mobile device.

[0122] TEEI area 610 has:

[0123] Trusted interactive interface module 611, used to obtain the original password input by the user;

[0124] A trusted storage module 612, configured to store the original password;

no. 3 approach

[0139] It can be seen from the above-mentioned first and second specific embodiments that the improvement of password protection measures in the present invention is mainly through an additional mobile smart device instead of the human brain for password input, so that the password is freed from the human brain. The input style is too single and fixed due to the mismatch of computing power with smart devices.

[0140] On this basis, the inventor further found that if the encrypted password is dynamically changed, the encrypted ciphertext generated by the wearable device is dynamically generated each time, which can better eliminate the risk of being copied.

[0141] Based on this transformation mechanism, in the third embodiment of the present invention, such a solution is applied to the existing card-free payment user login protection, which can solve the problem that the existing card-free payment is easy to be stolen when the login password is logged in as a user. problems,...

Abstract

The present invention relates to a password safety system for mobile device and an application method thereof. The system comprises: a safety device configured to obtain password and generate a password ciphertext in the password generation phase and then transmit the password ciphertext to a first mobile device, and configured to verify the password ciphertext sent by the first mobile device in the password verification phase; the first mobile device configured to receive generated password ciphertext and transmit the password ciphertext to a second mobile device in the password generation phase, and configured to read the password ciphertext and send to the safety device in the password verification phase; and the second mobile device configured to store the password ciphertext received from the mobile device in the password generation phase, and provide stored password ciphertext to the first mobile device in the password verification phase. According to the invention, the safety and the convenience of password usage may be improved.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a password security system for mobile equipment and a password security input method for mobile equipment. Background technique [0002] As smart mobile devices gradually become personal life assistants, more and more personal information is stored in smart mobile devices, which contain closely related private information, such as personal photos, social accounts, game accounts, etc. How to Security protection of these personal privacy information is a major security requirement of users for smart phones. [0003] The existing common technical means use the password method, that is, let the user set a password. When the user wants to protect personal information, the user is required to enter the password, and the smart mobile device judges whether the password is correct. If it is correct, the personal information is After that, if the user needs to view personal information...
