Abstract

Public key cryptography has become very popular recently. To use it securely, it
is necessary to employ systems offering at least a basic set of functions
associated with public key cryptosystems containing generation of keys, secure
generation of certificates, verification of signatures, dissemination of revoked
certificates, and so on. This paper demonstrates that the use of public key
cryptography is not easy and it is very difficult to perform the above-mentioned
actions in a way satisfying some predefined security level. The reason is in the
complexity of the problem. We are not generally able to ensure the usage of
systems able to work with all existing algorithms, key lengths, and formats in
the whole public key infrastructure. Also, some people are of the opinion that
X.509 as a basis ofr PKI is obsolete.
