Abstract (en)

[origin: DE19834934A1] The invention relates to a method for the secure transfer of data transferred as data blocks. The aim of the method is to achieve with little effort a high degree of security during the transfer of data. To this end the data blocks are temporarily stored in a temporary storage unit of the sender in the form of a quadratic matrix projected onto a spherical surface. Starting from a matrix bit designated by a position vector the position vector is placed onto one of the bits adjacent to the initial bit in the horizontal or vertical direction. The shift of the position vector by a column in the horizontal direction or a line in the vertical direction takes place in accordance with a directional vector determined by the state of the initial bit. Said initial bit is inverted and the process repeated for a number of times determined by a random number. The data block encoded in this way is decoded by reversing the process in the receiver module, taking into account the jointly transferred actual values of the position vector and directional vector.
