Abstract: There is provided a method of protecting the execution of a software application, the method performed by a plurality of processes comprising a process for executing the software application and a plurality of protection processes, wherein each protection process in the plurality of protection processes is configured to: monitor a process state of at least one other process in the plurality of processes to determine whether said process state corresponds to a predetermined process state; and perform a predetermined action in response to a determination that said process state corresponds to the predetermined process state; wherein the plurality of protection processes are configured such that a process state of the process for executing the software application is monitored by at least one protection process and a process state of each protection process is monitored by at least one other protection process in the plurality of protection processes. Additionally provided is a computer program and a system for carrying out the method and a computer readable medium for storing such a computer program.

Abstract: There is described a method of enabling a content receiver to access encrypted content, the content receiver forming part of a home network. The method comprises executing, on a device that also forms part of the home network, a key provisioning application. The method further comprises the key provisioning application receiving a key provisioning message and, based on the key provisioning message, providing to the content receiver via the home network one or more content decryption keys for decrypting the encrypted content. There is also described a device arranged to carry out this method. In addition, there is described a content receiver arranged to (a) receive from the aforementioned device, via a home network, one or more content decryption keys for accessing encrypted content; and (b) decrypt encrypted content using the one or more content decryption keys. Related computer programs and computer readable mediums are also described.
