“…Once discovered, the attacker can use various approaches and tools such as brute force cracking to destroy the cipher text, which greatly increases the risks with secret communication. In short, encryption technology hides the content of covert communication [7,8], while steganography technology hides the "behavior" of covert communication, so steganography technology is able to provide better concealment and security [9,10]. Table 1 compares the differences between steganography and encryption in five aspects [11].…”

The rapid advance and popularization of VoIP (Voice over IP) has also brought security issues. VoIP-based secure voice communication has two sides: first, for legitimate users, the secret voice can be embedded in the carrier and transmitted safely in the channel to prevent privacy leakage and ensure data security; second, for illegal users, the use of VoIP Voice communication hides and transmits illegal information, leading to security incidents. Therefore, in recent years, steganography and steganography analysis based on VoIP have gradually become research hotspots in the field of information security. Steganography and steganalysis based on VoIP can be divided into two categories, depending on where the secret information is embedded: steganography and steganalysis based on voice payload or protocol. The former mainly regards voice payload as the carrier, and steganography or steganalysis is performed with respect to the payload. It can be subdivided into steganography and steganalysis based on FBC (fixed codebook), LPC (linear prediction coefficient), and ACB (adaptive codebook). The latter uses various protocols as the carrier and performs steganography or steganalysis with respect to some fields of the protocol header and the timing of the voice packet. It can be divided into steganography and steganalysis based on the network layer, the transport layer, and the application layer. Recent research results of steganography and steganalysis based on protocol and voice payload are classified in this paper, and the paper also summarizes their characteristics, advantages, and disadvantages. The development direction of future research is analyzed. Therefore, this research can provide good help and guidance for researchers in related fields.

“…This kind of solutions cannot be generalized as usually VoIP communications are performed through the internet, and therefore, the effects of security applications are more critical than those in local networks. One recent interesting approach for Son et al has tested the Advanced Encryption Standard (AES) encryption and PKI by using RSA Rivest Shamir and Adelman algorithm on VoIP communications quality, but they only consider the delay factor. Moreover, Wanga and Liu also tested the AES and elliptic curve Diffie–Hellman for key exchange on VoIP quality.…”

“…In many cases, congestion on IP and internet networks prevents service providers and users from delivering an excellent quality for VoIP communications. It is worth to note that there exist considerable research proposals and solutions tackling the quality of service issues in VoIP networks . However, there is a paucity of research on VoIP security threats.…”

The early days of voice over IP (VoIP) adoption were characterized by a lack of concern and awareness about security issues related to its use. Indeed, service providers and users were mostly preoccupied with issues related to its quality, functionality, and cost. Now that VoIP is a mainstream communication technology, security has become a major issue. This paper investigates the major security threats for VoIP communications and proposes a multipath approach solution, especially targeted for low bandwidth networks. Results show that security has an effect on VoIP quality especially for a large distance between communicating nodes and packet size. Results also show that our proposed multipath solution reduces significantly packet losses and performs better than single routing techniques in networks with low bandwidth capacities.

“…Authentication and confidentiality are the main requirements inorder to secure any environment, For resource constrained environments many authentication schemes [1, 5-7, 12, 13, 16, 25, 26] and encryption schemes [8,21,23] are proposed, but unfortunately all these schemes are not well suited for future advanced wireless and mobile networks and its applications in multimedia, as the distinct authentication and encryption schemes double fold the resource requirements, Therefore a single process which combines both authenticion and encryption is of indespensible need. Fortunately Signcryption is the desired process which carries out encryption and digital signatures in one step not only to decrease computation cost but also communication cost and storage requirements.…”

The need for Lightweight cryptography is on the rise as transition has been made from wired to wireless network. Wireless systems inherently are insecure and resource (power) constrained, to deal with these constraints, many techniques for symmetric and asymmetric cryptography are defined. One such important developement is Signcryption to achieve message confidentiality, integrity, sender and message authentication, non repudiation, forward secrecy as well as unforgeability,and public verifiability. Since Signcryption combines the signature and encryption therefore the cost is very less in comparison to those schemes based on the signature then encryption. Many signcryption schemes have been proposed based on El-Gamal, RSA and ECC till today. This paper highlights limitations of the existing ECC based schemes using signcryption. These limitations include some missing security aspects as well as high computation power requirement, more communication overhead incurred and large memory requirements. Further it proposes an efficient lightweight signcryption scheme based on HECC which fulfills all the security requirements. The scheme reduced significant amounts of computation, communication costs and Multimed Tools Appl message size as compared to existing signcryption schemes making it the good candidate for environments suffer from the resource limitation problems.
