In this paper we present a few non cryptographic methods for improving the security, integrity and reliability of real time services. The methods presented in this paper apply to real time transmitting systems, which are based on the Peer-to-Peer (P2P) model. A basic idea of the first technique is to use agents for detecting steganographic content in packet headers, so packets with suspicious entries...
Public-key cryptosystems allow secure connections and data exchange through unsafe communication channel without the need of a previous secure key exchange. The most popular cryptosystem used nowadays is RSA. However recently a serious rival appeared - elliptic curve cryptosystems (ECC).Cryptanalytic attack on ECC system involves solving the elliptic curve discrete logarithm problem (ECDLP). The best...
