The invention discloses a dynamic security encryption method for Internet of Things. The method is used for establishing an initiative authentication mechanism and dynamic password authentication between wireless transmission devices. A system for implementing the method comprises a connecting device, a password book selecting device, an access code judging device, an authentication end pointer maintaining device, an authentication end pointer increasing device, an authentication judging device, a sending end pointer increasing device, a two-end pointer increasing device, a password pointer judging device, a connection maintaining device, a disconnecting device and an irregular authentication device. According to the method, connection is determined in an initiative password authentication mode, further, instead of use of a calculation result obtained with a single formula, irregular authentication and a two-factor authentication mode of password books and dynamic password pointers are adopted, accordingly, a Trojan horse program is prevented from getting a control right, and system automation can be realized.

The invention discloses a platform account sharing method which is characterized in that a user performs registration and topping-up on a platform called a user registration platform, namely that the platform registers the user name, login password and balance. The method comprises the following steps: when a user logs into another platform except the registration platform, if the platform does not have the registration information of the user, the user informs the registration platform thereof to send the registration information and balance to the platform; otherwise, the user informs the registration platform thereof to send the balance to the platform. The method has the following beneficial technical effects: the account information can be shared among all platforms through once registration to realize account transfer and prevent the risk of 'database attack' caused by password leak of some platform; and moreover, centralized management of the balance can be realized so that the balance can be used universally on all platforms and the risk of capital loss of the user caused by operation failure and bankruptcy of the platform is reduced.

The present invention relates to the field of charging devices and particularly relates to a shared charging device system and a multi-sequence encryption management method thereof. The multi-sequenceencryption management method includes the steps that: a plurality of sub-codes arranged in sequence are set; a charging device generates a dynamic password group including a plurality of sub-codes arranged in sequence and generates another dynamic password group again after the trigger is turned on, and a first sub-password of the dynamic password group is a next sub-password of a sub-password corresponding to an input when the trigger is turned on; a background management system generates a different pairing password in every time of communication connection with an intelligent mobile terminal, the intelligent mobile terminal is in communication connection with the background management system to obtain a pairing password to be a starting password matched with the dynamic password groupof the charging device; and the starting of the charging device is triggered by inputting the starting password. The background management system and the charging device are matched through independently generated pairing password and the dynamic password group to achieve the management of a shared charging device without the influence of a network, and the charging experience is improved.

The invention relates to the field of mobile power supplies, and specifically relates to a shared mobile power supply system and an encryption management method thereof. The encryption management method comprises the following steps: presetting a plurality of sub-passwords arranged in sequence; enabling a server to be in communication connection with mobile equipment and rental charging equipmentrespectively; generating a different dynamic password group containing the plurality of sub-passwords arranged in sequence by the rental charging equipment when each time the rental charging equipmentis disconnected from the server, wherein a first sub-password of the dynamic password group is a next sub-password of the input corresponding sub-password when the rental charging equipment is triggered to be opened; generating different pairing passwords by the server when each time the server is disconnected from the rental charging equipment and sending the pairing passwords to the mobile equipment as an open password matched with the dynamic password group; and inputting the open password to control to trigger to open the rental charging equipment. According to the encryption management method provided by the invention, the rental charging equipment can still be managed in the case of a poor network, and the mobile equipment is charged by using the rental charging equipment, thereby improving the charging experience.

Shared mobile power supply system and encryption management method thereof

The invention discloses a method for preventing a network account from being stolen by adopting a dynamic password technology. The method comprises the following steps of: binding a user network account with N authentication passwords, and authenticating by circularly using the passwords during user account operation. The method has low implementation cost, and is easy and convenient for a user to use, in addition, the configuration and the work flow of the conventional website system are not changed basically with the method. For certain network virtual electronic payment accounts, such as accounts of electronic commerce third party payment platforms including alipay, quick money and the like, user recharging accounts of online game websites, user recharging accounts of other various electronic commerce websites and the like, the account safety of a user can be protected by adopting the method disclosed by the invention, the accounts are prevented from being stolen by other people, and the safety performance of a system is enhanced.
