Opis:
Voice over Internet Protocol (VoIP) has been recently one of the more popular applications in Internet technology. It benefits lower cost of equipment, operation, and better integration with data applications than voice communications over telephone networks. However, the voice packets delivered over the Internet are not protected. The session initiation protocol (SIP) is widely used signaling protocol that controls communications on the Internet, typically using hypertext transport protocol (HTTP) digest authentication, which is vulnerable to many forms of attacks. This paper proposes a new secure authentication and key agreement scheme based on Digital Signature Algorithm (DSA) and Elliptic Curve Cryptography (ECC) named (ECDSA). Security analysis demonstrates that the proposed scheme can resist various attacks and it can be applied to authenticate the users with different SIP domains.

Opis:
A strong multiple designated verifiers signature (SMDVS) enables a signer to convince a set of verifiers by generating one signature, of which the verification needs a private key of a verifier. After a brief survey of current SMDVS schemes, we find no schemes suitable to a broadcast propagation, where the simulation needs only one verifier's private key. Motivated by this discovery, we propose a broadcast SMDVS scheme. The new scheme is proven secure in the random oracle model.

Opis:
Wireless sensor networks have received wide attention recently across the indoor and outdoor applications. On the other hand, more and more application scenarios require sensor nodes to be mobile, which imposes new technological challenges for security. Key management is the core for secure data communications among the resource-constrained sensor nodes. In this paper, based on the Group Diffie-Hellman key agreement protocols and the energy level of each node in the network, we propose Energy Aware Group Diffie-Hellman key management protocol for mobile wireless sensor networks. The simulation results show that the proposed key management protocol provide significant improvement in maximizing the lifetime of networks.

Opis:
One of the most recent challenges in communication system and network system is the privacy and security of information and communication session. Blockchain is one of technologies that use in sensing application in different important environments such as healthcare. In healthcare the patient privacy should be protected use high security system. Key agreement protocol based on lattice ensure the authentication and high protection against different types of attack especially impersonation and man in the middle attack where the latticebased protocol is quantum-withstand protocol. Proposed improved framework using lattice based key agreement protocol for application of block chain, with security analysis of many literatures that proposed different protocols has been presented with comparative study. The resultant new framework based on lattice overcome the latency limitation of block chain in the old framework and lowered the computation cost that depend on Elliptic curve Diffie-Hellman. Also, it ensures high privacy and protection of patient’s information.
