Lightweight security mechanism for PSTN-VoIP cooperation
Wojciech Mazurczyk, Zbigniew Kotulski
In this paper we describe a new, lightweight security mechanism for PSTN-VoIP cooperation that is based on two information hiding techniques: digital watermarking and steganography…
Security of mobile agents: a new concept of the integrity protection
Aneta Zwierko, Zbigniew Kotulski
The recent developments in the mobile technology (mobile phones, middleware) created a need for new methods of protecting the code transmitted through the network. The proposed mec…
Alternative security architecture for IP Telephony based on digital watermarking
Wojciech Mazurczyk, Zbigniew Kotulski
Problems with securing IP Telephony systems, insufficient standardization and lack of security mechanisms emerged the need for new approaches and solutions. In this paper a new, al…
Secret Sharing for n-Colorable Graphs with Application to Public Key Cryptography
Kamil Kulesza, Zbigniew Kotulski
At the beginning some results from the field of graph theory are presented. Next we show how to share a secret that is proper n-coloring of the graph, with the known structure. The…
On secret sharing for graphs
Kamil Kulesza, Zbigniew Kotulski
In the paper we discuss how to share the secrets, that are graphs. So, far secret sharing schemes were designed to work with numbers. As the first step, we propose conditions for "…
On the graph coloring check-digit scheme with applications to verifiable secret sharing
Kamil Kulesza, Zbigniew Kotulski
In the paper we apply graph vertex coloring for verification of secret shares. We start from showing how to convert any graph into the number and vice versa. Next, theoretical resu…
