Abstract: A method of operating a protection node for protecting a pattern classification node from malicious requests may be provided. The protection node may receive, from a user node, a request containing an original pattern to be classified by a machine learning algorithm performed by the pattern classification node. The protection node may add noise to the original pattern to generate a noisy pattern. The protection node may obtain a first classification of the noisy pattern based on processing of the noisy pattern by a first clone of the machine learning algorithm at the protection node; obtain a second classification of the original pattern based forwarding the request for processing of the original pattern by the machine learning algorithm performed at the pattern classification node; and compare the first and second classifications to determine whether the first and second classifications satisfy a defined similarity rule. The protection node may use the comparison to manage the request from the user node.

Abstract: A server (600), a client device (602) and methods therein, for handling cached content resources. When the client device (602) sends a download request (6:3) in a downloading session, the server (600) identifies (6:4) at least one content resource deemed to be potentially needed later in the downloading session. The server (600) then sends a cache map to the client device (602) in a response to the download request. The cache map comprises a pre-fetch indication indicating that the identified at least one content resource should be pre-fetched by the client device (602) from a cache (604) containing the identified at least one content resource. Thereby, the client device is able to pre-fetch (6:8) the content resources before the performance of communication may become reduced so that communication with the cache (604) is difficult or even impossible, e.g. due to deteriorated radio conditions or congestion in the communication network.

The actions facilitate caching the content in one or more caches. The one or more caches are selected from a plurality of caches based at least in part on proximity to the users to associated with the group.

Abstract: A server (500), a client device (502) and methods therein, for handling cached content resources. When receiving (5:3) a request from the client device (502) in a downloading session, the server (500) identifies (5:4) a set of caches (504, 506) that can be accessed by the client device (502). The server (500) then sends (5:6) a cache map to the client device (502) indicating that a first content resource is stored in a first cache (504) of the identified set of caches and a second content resource is stored in a second cache (506) of the identified set of caches. Thereby, the server (500) is able to adapt the cache map depending on which caches can be accessed by the client device (502), to ensure that the client device (502) can retrieve the content resources in an efficient manner.
