Patent DE-19801241-A1 (DE)
Inventor: MERTES LL M PAUL
IPC: H04L9/32
Filed: 1998-01-12
Abstract: Users need signature and coding keys for generating asymmetrical cryptographic keys. Reliable connections to a trust center are required for personalization and certification. Security problems arise when users wish to generate their own keys, more particularly, cryptographic keys. Said problems are diminished by a method, wherein the user initially receives a generated, personalized and certified pair of keys and components for generating coding pairs from the trust center. At a given moment, the user produces a coding pair of keys, signs the public part of said pair with the secret signature key assigned to him or her and transmits the result to the trust center, where the result is assigned to the user by means of the certified public part of the signature pair of keys. The invention can be particularly applied in all forms of asymmetric cryptographic methods, basically in money cards and bank transactions, access controls to networks and data banks, admission controls to buildings or rooms, digital signatures, digital identification and patient cards.

Patent DE-19834934-A1 (DE)
Inventor: BUTZMANN ULRICH
IPC: H04L9/06
Filed: 1998-07-29
Abstract: 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.
