Karolis Rubinas, Public Key Infrastructure implementation problems. The main object is a digital signature. The aim of this work is to find out the difficulties, witch prevents Public Key Infrastructure implementation. Goals was to: clear up the definition of a digital signature, find out how digital signature works and what is it for; analyze the structure and introduce it to the reader; compare the existing PKI situation in Lithuania with other countries; identify possible problems implementing a digital signature; compare Lithuanian qualified CA’s CP and CPS. Taking digital signature definitions into generalization, it is possible to conclude, that this is a digital technology, witch enables the user not only to sign the digital document and identify the person who signed, but also keeps the document from distortion and makes it unique. After analyzing the standards and legal documents I may say that the biggest problem implementing and developing PKI is REQUIREMENTS. In every step there are requirements witch you have to fulfill if you want to create a trustworthy and qualified PKI. Comparing the existing situation in Lithuania Digital signature in other countries is way more used and spread even though juridical base was completed by Lithuanians earlier than other countries, with more CAs. In addition it was revealed that there are five CAs in Lithuania, but only three of them produce qualified certificates. These are: UAB „Skaitmeninio sertifikavimo centras“, VĮ "Registrų centras“ and „Gyventojų registro tarnyba“. “„UAB Omnitel“ and „UAB Bitė Lietuva“ is not included in this list. This may be because of lack of meeting most of the requirements that were mentioned and those were not mentioned in this work. This work could be useful for business companies as well as for public organizations witch want to offer digital signature service. Also this is useful for digital signature users, who want to understand more about the digital signature operation, its purpose and benefits. |
