APPLICATION MANAGEMENT METHOD FOR TERMINAL, APPLICATION SERVER AND TERMINAL
Disclosed in the embodiments of the present invention are an application management method for a terminal, an application server and a terminal. The method comprises: upon receipt of an application download request sent by a terminal, an application server sending the corresponding application installation package to the terminal; then, receiving a first verification message sent by the terminal, the first verification message being generated by the terminal according to the content of the received application installation package; when determining that the first verification message is consistent with a stored second verification message, the application server sending an installation permission message to the terminal, so that the terminal installs the application according to the received application installation package. As the application server determines, according to the first verification message and the second verification message, the validity of the application installation package received by the terminal, it is unnecessary for the terminal to perform signature verification with a certificate, thereby reducing the effort of the terminal in managing certificates and improving application installation efficiency. When the application verification method needs to be upgraded, only the application server, rather than each terminal, needs to be upgraded, thereby improving the time-efficiency of application verification upgrading.

INTERCONNECTED REGION CONTROLLER, INTERCONNECTED REGION CONTROL METHOD, AND COMPUTER STORAGE MEDIUM
The present invention provides an interconnected region controller comprising an interconnected region routing module configured when a tenant is created. The interconnected region routing module is configured to: allocate a first identifier to the tenant for identifying traffic of the tenant; create a virtual routing forwarding instance for the tenant in a core switching network, and to bind the first identifier to the virtual routing forwarding instance; and to activate a dynamic routing protocol in the core switching network, and to bind a dynamic routing protocol instance to the virtual routing forwarding instance, wherein each virtual router corresponding to the tenant and distributed in multiple independent network partitions is associated with the interconnected region routing module. The invention further provides an interconnected region control method and a computer storage medium. The technical solution of the invention achieves a direct intranet connection in a heterogeneous SDN network region.
Disclosed in the present invention are a standardisation method and apparatus for erroneous transactions: receiving an erroneous service invocation request sent by a client terminal, and converting the erroneous service invocation request into a standard format exchange message; on the basis of a preset certificate database, encrypting sensitive data areas in the exchange message to generate encrypted message areas; signing key fields in the exchange message to generate signed message areas; and, by means of a two-way authenticated secure communication link, sending the exchange message comprising the encrypted message areas and the signed message areas to a UnionPay erroneous transaction network.

A METHOD AND SYSTEM FOR SECURELY AND AUTOMATICALLY DOWNLOADING A MASTER KEY IN A BANK CARD PAYMENT SYSTEM
A method and system for securely and automatically downloading a master key TMK in a bank card payment system is disclosed, wherein the bank card payment system includes a Point Of Sale POS, a Terminal Management system TMS, a PIN PAD and a HSM. A pair of public and private keys are generated by the TMS invoking the HSM. The master key TMK is randomly generated by the POS terminal invoking the PIN PAD. The TMK is encrypted with the public key of the TMS, and the encrypted TMK is uploaded to the TMS. The TMK is decrypted with the private key by the TMS invoking the HSM, and the decrypted TMK is stored. According to the present invention, the TMK is randomly generated, and the process of transmission is not exposed, and thus the TMK plaintext will not be exposed outside the secure storage devices. The TMK remains encrypted with the public key during the entire process of transmission. The TMK cipher text will not be decrypted until it reaches the HSM of the TMS. Thus, the present invention is of high security level.
