A method for end-to-end securing of transactions between a mobile terminal (1) and an internet server (5) at the application level, whereby cryptographic transaction identification documents (91), destined for transaction partner applications in the mobile terminal (1), from the internet server application are stored (92) for the mobile terminal (1), in a proxy server (6). The proxy server (6) calculates a document identification for each stored transaction identification document and a document proxy from the corresponding stored transaction identification document, transmits (94) the above to the mobile terminal (1), extracts a document identification and a document proxy from the information directed (95) to the internet server application from the mobile terminal (1). The compatibility (96) of the extracted document proxy is checked (97) with the document proxy which may be calculated from the stored transaction identification document corresponding to the extracted document identification and where there is compatibility (98) the stored transaction identification document determined by the extracted document identification is transmitted (99) to the internet server application.
