FIELD: data processing.

SUBSTANCE: invention relates to a method and a data processing system. Said method comprises the steps of receiving, using a computing device, two or more sub-tokens, each of a fixed size, wherein the sub-tokens together represent a larger token whose size exceeds said fixed size, while a larger token represents data that is immutable as long as the larger token is valid; obtaining a cryptographically strong key and information that identifies a source from which it is possible to obtain the data represented by the larger token, using a computing device from one or more of said sub-tokens; and providing, using a computing device, evidence of the key to the offload provider that includes at least one other computing device that is separate from said computing device, in order to get a portion of data represented by a large token without going through this part of the data through an initiator that provided the above-mentioned sub-tokens.

EFFECT: enabling the offload provider to use large tokens.
