Abstract [eng] |
This paper analyses issues of attribute certification in currently used electronic signatures. Fundamentals of electronic signatures and public key infrastructure are briefly described, focusing on possibilities of achieving higher security level in communication when attribute information is important. Various suggestions for attribute certification are analysed, introducing atribute certificates and atribute authorities. Different certification methods are compared and evaluated, applying the most suitable one in the public key infrastructure usage model, that is constructed by simplifying the current situation of electronic signatures. The solution is represented by describing the prototype of improved electronic signature infrastructure. |
