Abstract-We present a comprehensive survey of Voice over IP security academic research, using a set of 245 publications forming a closed cross-citation set. We classify these papers according to an extended version of the VoIP Security Alliance (VoIPSA) Threat Taxonomy. Our goal is to provide a roadmap for researchers seeking to understand existing capabilities and to identify gaps in addressing the numerous threats and vulnerabilities present in VoIP systems. We discuss the implications of our findings with respect to vulnerabilities reported in a variety of VoIP products.We identify two specific problem areas (denial of service, and service abuse) as requiring significant more attention from the research community. We also find that the overwhelming majority of the surveyed work takes a black box view of VoIP systems that avoids examining their internal structure and implementation. Such an approach may miss the mark in terms of addressing the main sources of vulnerabilities, i.e., implementation bugs and misconfigurations. Finally, we argue for further work on understanding cross-protocol and cross-mechanism vulnerabilities (emergent properties), which are the byproduct of a highly complex system-of-systems and an indication of the issues in future large-scale systems.

“…Also, a symmetric key can contain a stream cipher and a block cipher; the block cipher will be used here. The concept of a block cipher is to divide the text into fairly bulky blocks, for instance, 128 bits, then encode every block individually [2] [3].…”

Cryptography is a security technique that must be applied in both communication sides to protect the data during its transmission through the network from all kinds of attack. On the sender side, the original data will be changed into different symbols or shapes by using a known key; this is called encryption. On the other communication side, the decryption process will be done and the data will be returned to its former shape by using the agreed key. The importance of cryptography is to fulfil the communication security requirements. Real time applications (RTA) are vulnerable for the moment because of their big size. However, some of the current algorithms are not really appropriate for use with these kinds of information. In this paper, a novel symmetric block cipher cryptography algorithm has been illustrated and discussed. The system uses an 8x8x8 cube, and each cell contains a pair of binary inputs. The cube can provide a huge number of combinations that can produce a very strong algorithm and a long key size. Due to the lightweight and fast technique used in this idea, it is expected to be extremely rapid compared to the majority of current algorithms, such as DES and AES.

“…Compression technology techniques have developed as well as security systems. Furthermore, nowadays, computers, laptops, smartphones and other communication products have hundreds of applications that provide multimedia services over IP networks for free such as Skype [3]. The characteristics of RTA require a high bandwidth because of their large size.…”

Cryptography technology is one of the most important security methods that guarantee the security requirement such as confidentiality, integrity and nonrepudiation. The importance of the cryptography is very clear in transmitting a sensitive date through an open network such as Internet. Some of the current algorithms are not fully applicable with the Real Time Applications due to its sensitivity of time. In this paper, an encryption algorithm is suggested to deal with RTA's that is supposed to spend less time compared to the AES and Blowfish. The first of the proposed solution is that the key is regenerated with a different value in each single round from its sixth different rounds. The use of XOR operation is appropriate with RTA with reference to its lightweight and speed.
