The document proposes a system that provides authentication and confidentiality in a broker-less content-based publish/subscribe system. It adapts identity-based encryption mechanisms to ensure only subscribers with matching credentials can decrypt events. A secure overlay clusters subscribers to preserve weak subscription confidentiality. The system evaluates performance of the security mechanisms, finding authentication and encryption costs are proportional to subscribed attributes. Delays increase modestly with system size.

Empirical Study of a Key Authentication Scheme in Public Key CryptographyIJERA Editor
Public key cryptosystem plays major role in many online business applications. In public key cryptosystem, public key need not be protected for confidentiality, but the authenticity of public key is needed. Earlier, many key authentication schemes are developed based on discrete logarithms. Each scheme has its own drawbacks. We developed a secure key authentication scheme based on discrete logarithms to avoid the drawbacks of earlier schemes. In this paper, we illustrate the empirical study to show the experimental proof of our scheme.

Mitigating Various Attacks in Mobile Ad-hoc Networks Using Trust Based ApproachIJLT EMAS
A Mobile ad hoc network (MANET) is self-organizing,
decentralized and infrastructure-less wireless network. The
successful transmission of the data packet depends on the
complete cooperation of each node in the network. These types of
network don’t have permanent base station, so each node in the
network acts as a router. Due to openness, decentralized, selforganizing
nature of MANET, it is vulnerable to various attacks.
So security is the main concern in MANET.
In this project, we have considered 2 attacks; Vampire
attack and DDoS attacks. Vampire attack drains the energy of
the nodes. DDoS attack exhausts the resources available to a
network, such that the node cannot provide any services. Here,
we discuss methods 2 methods as a solution to our problem; one
is to prevent the attack from happening and other to detect and
recover from the attacks.

Security is one of the extensive and complicated requirements that need to be provided in order to achieve few issues like confidentiality, integrity and authentication. In a content-based publish/subscribe system, authentication is difficult to achieve since there exists no strong bonding between the end parties. Similarly, Integrity and confidentiality needs arise in published events and subscription conflicts with content-based routing. The basic tool to support confidentiality, integrity is encryption. In this paper for providing security mechanism in broker-less content-based publish/subscribe system we adapt pairing-based cryptography mechanism. In this mechanism, we use Identity Based Encryption (IBE) technique to achieve the needs of publish/subscribe system. This approach helps in providing fine-grained key management, effective encryption, decryption operations and routing is carried out in the order of subscribed attributes

Public subscribe systems are more attracted academic and industrial interest in last few years, including certain
experiences of development and deployment. The primary requirements of security mechanisms such as
authentication and confidentiality in content based publish subscribe system. This system consists of various
types of brokers or agents where these brokers are organize their roles. These brokers are information or events
are published by publishers and this information is received by subscribers and it depends on their subscription.
Publisher and subscriber system is loosely coupled and asynchronous communication and this system is based on
distributed system. Broker play vital role in business development and obtain by question mark over the
trustworthiness of broker. The used of security coupled system for Brokerless is huge demand. In addition to our

Efficient Instant-Fuzzy Search with Proximity Ranking
System finds answers to a query instantly while user types in keywords character-by-character.
Fuzzy search improves user search experiences by finding relevant answers with keywords similar to query keywords.
A main computational challenge in this paradigm is the high speed requirement
At the same time, we also need good ranking functions that consider the proximity of keywords to compute relevance scores
The previous systems were able to recommend results based on just previously typed characters kept in cache module.
Most of the times Previous Search Log might be useful to make recommendation system more faster!

Implementation is the stage of the project when the theoretical design is turned out into a working system. Thus it can be considered to be the most critical stage in achieving a successful new system and in giving the user, confidence that the new system will work and be effective.
The implementation stage involves careful planning, investigation of the existing system and it’s constraints on implementation, designing of methods to achieve changeover and evaluation of changeover methods.
Main Modules:-
1. User Module:
In this module, Users are having authentication and security to access the detail which is presented in the ontology system. Before accessing or searching the details user should have the account in that otherwise they should register first.
2. Secure DeDuplication System:
To support authorized deduplication, the tag of a file F will be determined by the file F and the privilege. To show the difference with traditional notation of
tag, we call it file token instead. To support authorized access, a secret key kp will be bounded with a privilege p to generate a file token. Let ϕ′ F;p = TagGen(F, kp) denote the token of F that is only allowed to access by user with privilege p. In another word, the token ϕ′ F;p could only be computed by the users with privilege p. As a result, if a file has been uploaded by a user with a duplicate token ϕ′
F;p, then a duplicate check sent from another user will be successful if and only if he also has the file F and privilege p. Such a token generation function could be
easily implemented as H(F, kp), where H(_) denotes a cryptographic hash function.
3. Security Of Duplicate Check Token :
We consider several types of privacy we need protect, that is, i) unforgeability of duplicate-check token: There are two types of adversaries, that is, external adversary and internal adversary. As shown below, the external adversary
can be viewed as an internal adversary without any privilege. If a user has privilege p, it requires that the adversary cannot forge and output a valid duplicate token with any other privilege p′ on any file F, where p does not match p′. Furthermore, it also requires that if the adversary does not make a request of token with its own privilege from private cloud server, it cannot forge and output a valid duplicate token with p on any F that has been queried.
4. Send Key:
Once the key request was received, the sender can send the key or he can decline it. With this key and request id which was generated at the time of sending key request the receiver can decrypt the message.

Securing Brokerless Publish/Subscribe Systems
Using Identity Based Encryption
ABSTRACT
The provisioning of basic security mechanisms such as authentication and
confidentiality is highly challenging in a content based publish/subscribe system.
Authentication of publishers and subscribers is difficult to achieve due to the
loose coupling of publishers and subscribers. Likewise, confidentiality of events
and subscriptions conflicts with content-based routing. This paper presents a
novel approach to provide confidentiality and authentication in a broker-less
content-based publish/subscribe system. The authentication of publishers and
subscribers as well as confidentiality of events is ensured, by adapting the
pairing-based cryptography mechanisms, to the needs of a publish/subscribe
system. Furthermore, an algorithm to cluster subscribers according to their
subscriptions preserves a weak notion of subscription confidentiality. In addition
to our previous work this paper contributes 1) use of searchable encryption to
enable efficient routing of encrypted events, 2) multicredential routing a new
event dissemination strategy to strengthen the weak subscription confidentiality,
and 3) thorough analysis of different attacks on subscription confidentiality. The
overall approach provides fine-grained key management and the cost for
encryption, decryption, and routing is in the order of subscribed attributes.
Moreover, the evaluations show that providing security is affordable w.r.t. 1)

throughput of the proposed cryptographic primitives, and 2) delays incurred
during the construction of the publish/subscribe overlay and the event
dissemination.
EXISTING SYSTEM:
In the past, most research has focused only on providing expressive and scalable
pub/sub systems, but little attention has been paid for the need of security.
Existing approaches toward secure pub/sub systems mostly rely on the presence
of a traditional broker network. These either address security under restricted
expressiveness, for example, by using only keyword matching for routing events
or rely on a network of (semi-)trusted brokers. Furthermore, existing approaches
use coarse-grain epoch based key management and cannot provide fine-grain
access control in a scalable manner. Nevertheless, security in broker-less pub/sub
systems, where the subscribers are clustered according to their subscriptions, has
not been discussed yet in the literature.
PROPOSED SYSTEM:
Proposed System presents a new approach to provide authentication and
confidentiality in a broker-less pub/sub system. Our approach allow subscribers
to maintain credentials according to their subscriptions. Private keys assigned to
the subscribers are labeled with the credentials. A publisher associates each
encrypted event with a set of credentials. We adapted identity-based encryption
(IBE) mechanisms 1) to ensure that a particular subscriber can decrypt an event
only if there is a match between the credentials associated with the event and the

key; and 2) to allow subscribers to verify the authenticity of received events.
Furthermore, we address the issue of subscription confidentiality in the presence
of semantic clustering of subscribers. A weaker notion of subscription
confidentiality is defined and a secure overlay maintenance protocol is designed
to preserve the weak subscription confidentiality.
PROBLEM STATEMENT:
It include two entities in the system: publishers and subscribers. Both the entities are
computationally bounded and do not trust each other. Moreover, all the peers (publishers
or subscribers) participating in the pub/sub overlay network are honest and do not deviate
from the designed protocol. Likewise, authorized publishers only disseminate valid
events in the system. However, malicious publishers may masquerade the authorized
publishers and spam the overlay network with fake and duplicate events. We do not
intend to solve the digital copyright problem; therefore, authorized subscribers do not
reveal the content of successfully decrypted events to other subscribers.
SCOPE:
The pub/sub overlay proposed is similar to DPS system with modifications to
ensure subscription confidentiality. In this paper, we, therefore, evaluate
performance and scalability of the proposed pub/sub system only with respect to
the security mechanisms and omit other aspects. In particular, we evaluate the
performance of our system the overlay construction time and the event
dissemination delays. We measure the average delay experienced by each
subscriber to connect to a suitable position in an attribute tree. Delay is measured
from the time a subscriber sends connection request message to a random peer in
the tree till the time the connection is actually established. The evaluations are

performed only for a single attribute tree. It shows that the average connection
time (delay) increases with the number of peers in the system because of the
increase in the height of the attribute tree (each new hop increases the network
delay as well as time to apply security methods).
MODULE DESCRIPTION:
Number of Modules
After careful analysis the system has been identified to have the following
modules:
1. Content-Based Publish/Subcriber Module.
2. Identity Based Encryption Module.
3. Key Generation for Publisher/Subscriber Module.
4. Secure Overlay Maintenance Module.
1.Content-Based Publish/Subscriber Module:
The routing of events from publishers to the relevant subscribers, we use the
content-based data model. We consider pub/sub in a setting where there exists
no dedicated broker infrastructure. Publishers and subscribers contribute as
peers to the maintenance of a self-organizing overlay structure. To authenticate
publishers, we use the concept of advertisements in which a publisher announces
beforehand the set of events which it intends to publish.

2.Identity Based Encryption Module:
In our approach, publishers and subscribers interact with a key server. They
provide credentials to the key server and in turn receive keys which fit the
expressed capabilities in the credentials. Subsequently, those keys can be used to
encrypt, decrypt, and sign relevant messages in the content based pub/sub
system, i.e., the credential becomes authorized by the key server. The keys
assigned to publishers and subscribers, and the ciphertexts, are labeled with
credentials. In particular, the identity-based encryption ensures that a particular
key can decrypt a particular ciphertext only if there is a match between the
credentials of the ciphertext and the key. Publishers and subscribers maintain
separate private keys for each authorized credential.
3. Key Generation For Publisher/Subscriber Module:
Publisher keys: Before starting to publish events, a publisher contacts the key
server along with the credentials for each attribute in its advertisement. If the
publisher is allowed to publish events according to its credentials, the key server
will generate separate private keys for each credential. The public key of a
publisher p for credential is generated.
Subscriber keys: Similarly, to receive events matching its subscription, a
subscriber should contact the key server and receive the private keys for the
credentials associated with each attribute A.

4.Secure Overlay Maintenance Module:
The secure overlay maintenance protocol is based on the idea that in the tree,
subscribers are always connected according to the containment relationship
between their credential. A new subscriber s generates a random key SW and
encrypts it with the public keys for all credentials that cover its own credential,
for example, a subscriber with credential will generate ciphertexts by applying
the public keys. The generated cipher texts are added to a connection request
(CR) and the request is forwarded to a random peer in the tree. A connection is
established if the peer can decrypt any of the cipher text using its private keys.
