Abstract: Provided are a key derivation method and device. The method includes: acquiring a slice identifier corresponding to a network slice to which a user equipment is currently attached, where the slice identifier uniquely identifies the network slice; and transmitting the slice identifier to a designated communication device. The slice identifier is configured to instruct the designated communication device to derive, according to the slice identifier, an intermediate key required by the network slice. By means of the technical solution described above, the problem in the related art that a slice function cannot be implemented normally due to the fact that different network slices probably use the same intermediate key may be solved, and different network slices may correspond to different intermediate keys, thereby avoiding a case that the slicing function cannot be implemented normally caused by allocating the same intermediate key to different network slices.

Abstract: Systems and methods are directed to enabling a client device to insert customized content from a first server into a container page received from a second server without using an asynchronous data fetching protocol. The second server determines contextual information related to the client device and prepares a container page that includes an image link having a cryptographically verifiable representation of a set of one or more parameters based on the contextual information. The client device receives and uses the image link to send, to the first server, an image request with the cryptographically verifiable representation of the parameter set. The first server verifies the cryptographically verifiable representation, and uses the set of parameters to generate a customized image. The client device receives and renders the customized image within the container page without reloading the container page.

Abstract: A novel solution to the vexing problem of how to secure a cashless transaction card and card account from unauthorized use. By adding enhanced security to a cashless transaction card, the present invention significantly reduces, and may in fact eliminate, unauthorized use of a cashless transaction card and card account. In accordance with embodiments of the present invention, a cashless transaction card and card account are linked with an authentication device that must be in proximity with the cashless transaction card when that card is being used for a cashless transaction. In this way, the present invention makes unauthorized use of the card significantly less likely. The authentication device is chosen by the owner and linked thereby with the cashless transaction card and card account. Only when the authentication device is in proximity with the cashless transaction card will a cashless transaction be authorized.
