Abstract: The present invention relates to electronic payments in a mobile communication system, methods and arrangements for secure transmission using SMS in a mobile communication system. In a method data and a PIN-code are stored in a memory in a mobile terminal. A first bit sequence is created from the data and the PIN-code where different 8-bit combinations represent each character of the data and the PIN-code. Next the first bit sequence is encrypted using a PKI (Public Key Infrastructure) public-key to create a second bit sequence. A sequence of characters is then created from the second bit sequence, where each character in the sequence of characters is represented by an 8-bit combination. The characters are then transposed to 7-bit characters to create a third bit sequence which is transmitted to a server using SMS. The data, PIN-code and first bit sequence are also erased from the memory in the mobile terminal.

Abstract: A casting mould for keeping the cast compound together and supporting it on casting elongated objects, standing on an underlayer and extending vertically comprises a flexible elongated envelope (3) being substantially inelastic and having an opening (7) at one end thereof for supplying cast compound (6). The envelope is arranged to be held substantially vertically while being stretched by cast compound introduced through said opening (7) so as to form a casting mould having a circular cross-section, extending vertically and supporting and keeping the cast compound together.
