The invention discloses a safe distributed duplicated data deletion method. According to the method, a file is segmented into fragments through a secret sharing technology without any encryption mechanism. The shared fragments are distributed in a plurality of independent storage servers. In addition, in order to support reduplication removing, a different short value is calculated and sent to the storage servers as the indicator of one fragment. Only possessors uploading data for the first time need to carry out such calculation and distribution of secrete sharing, and then people possessing the same data copies do not need to calculate and store the sharing any longer. When the data copies are restored, users must access the storage servers with the minimum quantity to reconstruct the data through authentication and acquisition of the secret sharing. In other words, the secret sharing of the data can only be accessed by the users who possess the same copies and are authorized.

This invention discloses a method for protecting data of charge cards of a charge center in an intelligent network including: applying an encrypted cryptographic key in the public key system to encrypt information in the charge card data to generate attached verification information and loading recordings of charge cards containing said attached check information, when a user is charged, the intelligent network charge center applies a de-ciphered cryptographic key corresponding to the key to de-cipher the attached verification information corresponding to the charge center. This invention alsodiscloses a data encrypting method, a de-ciphering method to charge card data, a system for protecting the charge card data, a card-issuing customer end and a charge center of an intelligent network.

The invention discloses a method and a system for extending software functions, an upper-layer software client and a remote function server. The method includes that the upper-layer software client calls the remote function server according to parameters configured in advance; the remote function server logs in a lower-layer software server according to the parameters configured in advance, and an interface of a lower-layer software client is transmitted to the upper-layer software client in an interface remote mode. The system comprises the upper-layer software client and the remote function server. The upper-layer software client comprises a parameter configuring module, a calling module and a receiving module. The remote function server comprises a target plug-in module and a target graphical user interface (GUI) program module. The method, the system, the upper-layer software client and the remote function server have the advantages that the software functions are extended in the interface remote mode under the condition that original software function codes are not changed, and the safety and the confidentiality of lower-layer software are protected.

In packet switched communications systems, a number of techniques exist for measuring packet loss, but each of these has respective disadvantages, each of varying degree. Consequently, the present invention provides a method of generating a test packet for measuring packet loss, where an initial packet is encapsulated with a first shim header (300), the encapsulated initial packet being encapsulated with a second shim header (306). The first shim header (300) has a label (308), the label (308) being indicative of a monitoring status of the test packet and used to identify the monitoring status of the packet as the test packet traverses a Label Switched Path of a Multi-Protocol Label Switched network. An advantage of using this technique is that the trailers of the test packet can be easily forwarded to an Internet Protocol (IP) address of a monitoring station, when the initial packet is an IP packet.

Existing approaches to security in networks such as the oneM2M network are limited. For example, content may only be protected if it is transmitted between mutually trusted entities. Here, the integrity and confidentiality of the content in the M2M network is protected. Such content may be "stationary" such that the content is stored at the hosting node. Only authorized entities can store and retrieve data stored at the hosting node, and the data can be protected from a confidentiality and integrity perspective.
