Verfahren zur Generierung asymmetrischer Kryptoschlüssel beim Anwender

摘要

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.
