1. Abstract

Summary – Addresses the security and fault tolerance issue communication in the presence of opponents via multi-hop wireless networks with frequently changing topologies. We design and evaluate Secure Message Transfer (SMT) protocol and its alternative, the Secure Single-Path Protocol (SSP), to effectively deal with arbitrary and malicious interruptions of data transmission.

One of the distinguishing features of SMT and SSP is that they can operate exclusively in an end-to-end manner without limiting assumptions about trust and security associations in the network. As a result, the protocol is applicable to a wide range network architecture. We demonstrate that reliable communication with low latency and low delay variability can be maintained even when a significant part of network nodes systematically or intermittently disrupts communication. SMT and SSP reliably detect transmission errors, avoid and tolerate data loss and continuously configure operations to ensure communication availability. This is achieved at the cost of moderation tradable transmission and routing overheaddelay.Overall,theprotocol'sabilitytomitigate both malicious and harmless errors enables fast and reliabledatatransmissioneveninhighlyhostilenetwork environments.

THE EMERGING Mobile Network (MANET) technology is based on multi-hop wireless architecture and does not require fixed infrastructure or preconfiguration of network nodes. The salient features of thisnewnetworkparadigmis:

1) Joint support of basic network functions such as routinganddatatransfer

2) Lack of administrative boundaries for network nodes;

3) Nocentralpointinthenetwork

4) In general, temporary associations of network nodes.

As a result, a node cannot make assumptions about the trustworthiness of the peers that assist it in communication and typically do not have credentials Securing basic network operations is becoming a major concernandindeedarequirementforad-hocnetworks.

Recently, many papers have proposed secure routing mechanisms to defend against different attacks under different assumptions and system requirements. However, a secure routing protocol that guarantees correct route finding alone cannot guarantee safe and problem-freedatadelivery.Inotherwords,acorrectand up-to-date route cannot automatically be considered hostile-free. For example, a sophisticated attacker could followthe routediscovery rules,be placedonthe route, and later start redirecting traffic, dropping packets, or forging and injecting. Of course, attackers can hide their malicious behavior for long periods of time and launch attacks at unexpected times. Therefore, it is impossible to detect such an enemy before attacking. For detecting such enemy attacks we need to threw the data to surf intothethings.

The combination of Internet Protocol (IP) address and public key uniquely identifies a node. Any twonodesthatwishtocommunicateinasecuremanner are assumed to be able to establish an endto- end security association (SA). Symmetric-key cryptographic primitives are computationally more efficient than public-key ones, so assuming a symmetric shared key instantiates an SA between end nodes, source and

Details and examples of distributed algorithms, which basically behave like erasure codes, are given in. A computed Message Authentication Code (MAC) and a sequence number are added to each part to verify the integrity and authenticity of the original, and the traffic is then denied.

Reference [44] proposes stimulating rational node cooperation through fictitious currencies and rewards,and[45]proposesgame-theoreticmotivations for reputation systems. In contrast to and earlier work, SMT offers a solution tailored to his MANET environment that combines her four elements: 1) Reliance on end-to-end security bindings only. 2) Simultaneous transmission over several different paths determined by the protocol. 3) Robust detection of communication errors. 4) Adaptation to network conditions. Such or similar features are proposed separately.[10],[12]–[14],and[46],butnevercombined them into a single protocol. SMT can work with secure routing protocols to provide comprehensive security by protecting the data transfer phase. On the other hand, SMT's robust end-toend error detection can prevent abuse of such protocol's route maintenance operations and prevent attackers from hiding or reporting erroneous route error messages. In addition, SMT does not require a long observation period to characterize a misbehaving node as an adversary, and is susceptible to ``intimidation'' attacks by adversaries who disseminate falsereportsofmisbehaving.

CONCLUSION

We present and analyze SMT and SSP protocols for secure data communication in ad- hoc networks. These two protocols are widely used because they provide lightweight end-to- end security services and operate without knowing the trustworthiness of individual network nodes. They are highly effective and provide veryreliable,low-latency,low-jittercommunicationeven in very hostile environments. SMT supports real-time communication, provides near-constant latency and

jitter, and delivers 93% of messages without retransmitting, even when 50% of network nodes stop sending data. For example, if 30% of the network nodes arehostile,evenwithasmallnumberofroutesavailable, SMT can deliver over 98% of messages with limited retransmissions. The SMT and SSP are versatile because they automatically adapt to resource-constrained environments and application requirements. In fact, our protocol covers a wide range of solutions, offering the flexibility to trade off overhead for better resilience and reliability, or trade delay and delay variability for low overhead. increase. For example, SSP has less than onethird the network overhead of SMT, yet is as reliable as SMT. At the same time, their customizations are robust astheycannotbeexploitedbyattackersandareresilient to random data transfer interruptions. Finally, components of SMT and SSP such as error detection or path survival estimation may be applicable to other types of networks (such as wired) and other communicationpatterns(suchasmulticast).

Overall, data communication security and fault tolerance are paramount in an inherently insecure and unreliablead-hocnetworkenvironment.
