A Survey on Cloud-Based IP Trace Back FrameworkIRJET Journal

��

This document summarizes a survey of cloud-based IP traceback frameworks. It proposes a cloud-based traceback architecture with three layers: an intra-AS layer where traceback servers in each Autonomous System (AS) collect and store traffic flow data; a traceback as a service layer where ASes expose their traceback capabilities; and an inter-AS logical links layer to facilitate efficient traceback across ASes. It then focuses on access control to prevent unauthorized users from requesting traceback information. To address this, it proposes a temporal token-based authentication framework called FACT that embeds tokens in traffic flows and delivers them to end hosts to authenticate traceback queries. The framework aims to ensure only actual recipients of packets can initiate traceback for those packets.

The document discusses the history and development of virtual private networks (VPNs). It explains that early VPNs used IPSec but had problems with complexity and interoperability. This led to the development of user-space VPNs using virtual network interfaces and encapsulating IP packets in UDP for transmission over public networks like the internet. OpenVPN is highlighted as an open-source user-space VPN that follows this model and provides a more portable and easier to configure alternative to IPSec VPNs.

Internet Protocol Security as the Network Cryptography SystemUniversitas Pembangunan Panca Budi

��

Internet Protocol Security (IP Security) is a security protocol that serves to secure information in the event of an exchange on the internet. It happens if there is a connection between private IP and public IP. This protocol will exchange packets on the IP layer safely. It provides two types of encryption options, transport, and tunnel. Transport mode will encrypt the data section without changing the packet header. The algorithm used to encrypt data is a symmetric cryptography algorithm. This protocol authenticates and encrypts every packet from a data transmission session. Also, it can generate keys between the sender and the recipient at the first time it is activated and can negotiate the cryptographic keys that will be used during the session. IP Security is an end-to-end cryptosystem that works at the internet layer of the Internet Protocol Suite. The protocol serves to protect the data flow in host-to-host, network-to-network, and network-to-host as well.

EFFICIENT DEFENSE SYSTEM FOR IP SPOOFING IN NETWORKScscpconf

��

In this age of gigabit Ethernet and broadband internet, network security has been the top priority for most of the researchers. Technology advancements have advantages as well as disadvantages. Most of the communication of present world, the e-world, takes place online, through the internet. Thus the context of network intrusions and attacks to hack into servers also came into existence. A technique to perform this activity is made possible by preventing the discovery of the sender’s identity through IP Spoofing [7]. Many popular internet sites have been hacked and attackers try to forge or spoof the source addresses in IP packets. Using spoofing detection technique, the user can retrieve the list of IP addresses and able to identify the malicious IP addresses.Hence mechanisms must be designed to prevent hacking. This paper proposes a novel technique to detect IP spoofing based on traffic verification and filtering

A Location Based Cryptosystem For Mobile Devices Using Improved Rabin AlgorithmEditor IJMTER

��

As per the recent studies, the volatile growth has been seen in the use of mobile devices as the supporting technology for accessing Internet based services, as well as for personal communication needs in networking. Various studies indicate that it is impossible to utilize strong cryptographic functions for implementing security protocols on mobile devices. Our research negates this. Explicitly, a performance analysis focused on the most commonly used cryptographic protocols based on the location address (latitude & longitude) of the user for mobile applications and projected provably secure authentication protocol that is more efficient than any of the prevailing authentication protocol is being used by the network security methods. Understanding the use of public key cryptography which makes potential use of discrete logarithms problem. The security of ECC depends on the difficulty of Elliptic Curve Discrete Logarithm. To provide secure communication for mobile devices, authenticated protocol is an important primitive for establishing trusted connection. In this paper, it has been shown that the location based system using improved Rabin Algorithm provides a better security and acquires much less energy consumption than the existing authentication protocols.

The results found that wired and WiMAX networks provided the best VoIP quality with high mean opinion scores and low delay and jitter. UMTS had the worst performance with high delay and packet loss affecting voice quality.
