FIELD: information dissemination systems.;SUBSTANCE: in accordance to the invention, encoded event, containing information which is not meant to be published before time of publishing, is dispatched to clients before the time of publishing. In the moment of the time of publishing, small decryption key is dispatched to each client. In another variant, highly reliable boundary servers, which can be trusted not to publish the information before appropriate time, dispatch non-encrypted event or decode an encrypted event and dispatch decrypted event in certain time or before it, but after the time of publishing, so that decrypted or non-encrypted event reached clients, which can not store and decrypt an encrypted event, approximately at the same time when the key reaches other clients. Therefore, every client may receive information at approximately one and the same time, independently from client throughput or client capacity for storage and decryption of information.;EFFECT: ensured valid dissemination between various clients.;10 cl, 7 dwg
