Abstract:
A method, a system and a computer program product for file transfer between a source node and a target node in a communications network are disclosed. The method comprises the steps of generating and storing a first hash product of a file; sending the first hash product to the target node via the communications network; receiving the first hash product as a second hash product from the target node via the communications network; generating a third hash product of the file; comparing the first, second and third hash products; and sending the file to the target node via the communications network if the first, second and third hash products match. Optionally, the method comprises the further steps of sending the matching hash product to the target node as a fourth hash product; receiving, from the target node, a result of a comparison between the second hash product, the fourth hash product and a fifth hash product generated at the target node from the file; and determining an integrity of the transferred file based on the result. The method is applicable for integration with the File Transfer Protocol (FTP).
