The only an important role to exchange information form one mobile encryption involved during transmission is the encryption to another. SMS is a popular medium for delivering value between the base transceiver station and the mobile station.

Wireless LAN two modes: Ad Hoc vs Infrastructure

Therefore, there is a need to provide secure B. Instead, each node participates in routing by forwarding data for other nodes dynamically based on the network connectivity. Ad-hoc wireless network Fig. Ad-hoc Network in Minatory Application In addition to the classic routing, ad hoc networks can use flooding for forwarding the data.

Nodes of ad-hoc networks 7. Power limitation multi-hop relay is needed are often mobile, which also implicates that they apply 8. Scalability issues wireless communication to maintain the connectivity, in 9. In ad-hoc networks, nodes Query all sensors that sensed something without using any pre-existing network infrastructure and particular in the past hour which can form any arbitrary topology. The emerging need for mobile ad hoc networks and secured data transmission II.

We will discuss here the As MANET is based on dynamic topology and is self- literature review of wireless infrastructure based network as organizing concept, so there are many challenges that the well as wireless infrastructureless network. Some of these challenges are: Wireless Infrastructure based Networks 1.

Lisonek and M. For securing, it has been chosen the asymmetric cipher RSA. RSA performs signature bit keys has not been successfully implemented yet. Franke University of for signature generation. The scheme described in paper [12] Bonn was able to factorize number with a length of bits. Using PKI we building up the dictionary because it is used in the OAEP can be sure that a signature was really made by the person in padding scheme.

The paper [5] describes that in , possession of the private key. Since the keys are created roughly 13 percent of the US population had cell phones; by within the device and the private key is never exposed June , it was 80 percent.

In , In the second quarter of key size algorithms are not suitable for SMS encryption due , Verizon Wireless alone says it handled Toorani and A. SMS uses only [14]. It efficiently combines encryption and digital signature a set of characters as data type. It requires very low and uses public keys for a secure key establishment to be bandwidth and it is a low cost service compared with others used for encrypting the short messages via a symmetric which makes it suitable for a set of applications. If message encryption. Since it deploys elliptic curves and a symmetric delivery is not possible, for example if the mobile device is encryption algorithm, it has great computational advantages not available, the service center regularly stores the message over the previously proposed public key solutions while for a time 24 hours and delivers it when the cell phone is simultaneously providing the most feasible security services.

Since the original design of short message service The paper [15] presents a comprehensive analysis of the has restrictions. It was created to deliver a message from a energy requirements of a wide range of cryptographic mobile device to another. Moreover, the message has limited algorithms that form the building blocks of security to maximum number of characters. Furthermore, it does not mechanisms such as security protocols.

In [16], m-payment have a process for authentication and the text is sent plain transaction model between consumer and merchant in m- without encryption. In addition to service restrictions, mobile commerce is easy for payment anywhere and anytime devices prevents of using security schemes highly reliable because it is SMS-based, advanced mobile phones are not because they use to have short memory and low processing needed, and no extra charges are imposed by third-party capabilities compared with desktop or portable computers.

This is especially true for SMS messages The paper [8] proposes Home Network architecture which do not integrate any security mechanism. The main for message encryption and authentication that was designed objective of the integrated system is to remotely monitor and with the limited memory and processing power of a mobile control the devices in the Home Network via computer or device in mind; and a protocol that will ensure their GSM mobile terminal.

The main contribution in [9] is a confidentiality and integrity. Hosain et al proposes a security system for with electronic identity application are used. Over the past many years is desired not to be disclosed to a third party. In this paper an several leading banks in India have launched SMS banking application for sending encrypted SMS messages using services. However, the security of mobile SMS payment and cryptographic methods based on theory of quasigroups is banking has topped the list of concerns for most of the proposed.

The encryption algorithm is characterized by a customers. In this paper [18], an investigation about the secret key [10]. It contains a high security node [28]. A pair of attacker nodes may create a wormhole authentication mechanism, which confirms true identities and [29] and shortcut the normal flows between each other. In the generates the bits session key. Paper [20] presents may target the route maintenance process and advertise that high security communication protocol for SMS. Through an operational link is broken [26]. The paper [21] shows an end-to-end facto standard IEEE It is well known that The The attacker may exploit its binary exponential backoff scheme to deny access B.

Wireless Infrastructureless Networks to the wireless channel from its local neighbors [31, 32]. In DSR and AODV are reactive protocols, only used when the MANET context, the prevention component is mainly new destinations are sought, a route breaks, or a route is no achieved by secure ad hoc routing protocols that prevent the longer in use.

  • One of the most popular protocols which are attacker from installing incorrect routing states at other nodes. Unfortunately, AODV do These protocols are typically based on earlier ad hoc routing not define special security mechanisms. The bad news is that protocols such as DSR [23], and AODV [22], and employ there are only a few proposed solutions to solve this problem different cryptographic primitives e.

    Several researchers tried to improve security weakness in III. SAODV [41] uses anonymity which are necessary to develop a secure network. TAODV [42] uses trust metrics to allow communicating partner; for better routing decisions and penalize uncooperative nodes. Non-repudiation means the origin of a message cannot Zapata and Asokan propose SAODV [41], a secure version deny having sent the message; of AODV, which uses digital signatures and hash chains to Availability means the normal service provision in face of secure the routing messages.

    Meka et al. Obviously, access The family of routing attacks refers to any action of control is tied to authentication attributes. In the context of DSR [23], the attacker may Anonymity means that all the information that can be modify the source route listed in the RREQ or RREP packets used to identify the owner or the current user of the node by deleting a node from the list, switching the order of nodes should default be private and not be distributed by he node in the list, or appending a new node into the list [26].

    When itself or the system software. The into two classes: Such challenge is to develop efficient algorithms which can attacks are usually difficult to detect and hence, defending provide more security in order to reduce response time time against such attacks is complicated. An Active Attack, complexity and required memory space complexity.

    Some of these original algorithms have already authentication, or attract packets destined to other nodes. The broken. Some padding schemes can be used to make the goal is basically to attract all packets to the attacker for network more secure like PKCS5 padding for symmetric analysis or to disable the network. Such attacks can be algorithms and PKCS1 padding for asymmetric algorithms. Security in wireless network both infrastructure based network and infrastructureless can be provided by some A. Security Attacks in Wireless Infrastructure based Network cryptographic approaches.

    Some of these approaches are: Understanding the basics of message security opens the Secure Authentication and Confidentiality Encryption door to preventing some common security threats in message approaches: Based on the routing Secure Non-repudiation Digital Signature approaches: Network-layer vulnerabilities generally VI.

    Most prominent attacks against ad-hoc networks are encrypted and digitally signed in order to maintain the active attacks. These attacks are: Attacks based on integrity of message in such kind of networks. The challenge modification; Attacks by Fabrication of Information; Denial is to develop efficient algorithms which can provide more of Service DoS ; Impersonation; Disclosure; Location security in order to reduce response time time complexity Disclosure; Replay Attack; Blackmail; Rushing Attack; and required memory space complexity.
