Abstract: A method, system and related apparatus are described, the system comprising a caching-capable element which is part of a data network, which receives a request from a downstream client device, the request including a content request, the content request including a Universal Resource Identifier (URI) and an explicit caching request, the caching request includes a unique content identifier which is independent of the URI, and optional expiration date information, a comparator included at the caching-capable element which compares the caching request against the existing cached content, and if the requested content is cached then the caching-capable element forwards the cached copy of the requested content to the client device, and if the requested content is not cached, then the caching-capable element forwards the request to a further upstream device, and, upon reception of the requested content from the further upstream device, returns the requested content to the requesting downstream device, and caches the requested content for further distribution to other clients. Related methods, systems and apparatus are also described.

Abstract: In one embodiment, a processing device includes a memory to store an executable program including a multiplicity of encrypted component blocks such that different combinations of blocks selected from the encrypted component blocks are operative when decrypted and executed to perform a same functionally equivalent data transformation, each of the component blocks being operative upon execution to convert input data into output data, and a processor operative to receive a selection of cryptographic keys, decrypt some of the encrypted component blocks using the cryptographic keys such that each one of the some encrypted component blocks is decrypted with a different one of the cryptographic keys yielding a multiplicity of decrypted component blocks, and execute the executable program including the multiplicity of decrypted component blocks to perform the same functionally equivalent data transformation. Related apparatus and methods are also described.
