                    <dim:field mdschema="dc" element="description" qualifier="abstract">Security of the qualified digital signature depends primarily on the choice of cryptographic algorithms and length of the keys used. In this paper we analyzed the Certification Authority in Serbia that issue qualified digital certificates. The analysis includes comparison of parameters and standards used with the recommendations of relevant international organizations. The focus of the analysis has bee put on the selection of a cryptographic algorithm, hash functions and length of the keys used.</dim:field>
