Seminar on Nymble: Anonymous IP-Address Blocking



Abstract

. Anonymizing networks such as Tor allow users to access Internet services
privately using a series of routers to hide the client’s IP address from the
server. Tor’s success, however, has been limited by users employing this anonymity
for abusive purposes, such as defacingWikipedia.Website administrators rely on IPaddress
blocking for disabling access to misbehaving users, but this is not practical
if the abuser routes through Tor. As a re ....etc

Networked computer systems are rapidly growing in importance as the medium of choice for the storage and exchange of information. However, current systems afford little privacy to their users, and typically store any given data item in only one or a few fixed places, creating a central point of failure. Because of a continued desire among individuals to protect the privacy of their authorship or readership of various types of sensitive information, and the undesirability of central points of failure which can be attacked by opponents wishing t ....etc

The rapid growth of Internet usage raised concerns over the privacy of communication and information dissemination. For example, Number of online advertising companies uses traffic analysis to learn the browsing habit of the target users and launch the advertisements accordingly. Corporate companies could use traffic analysis to monitor, when the competitor visits its website, and track what pages or products that interest the competitor. And the privacy loses in defense organizations matters more. Anonymous communication is a ....etc

Abstract
Onion Routing is an infrastructure for private com-
munication over a public network. It provides anony-
mous connections that are strongly resistant to both
eavesdropping and tra_c analysis. Onion routing's
anonymous connections are bidirectional and near real-
time, and can be used anywhere a socket connection
can be used. Any identifying information must be in
the data stream carried over an anonymous connec-
tion. An onion is a data structure that is treated as the
destination address by onion routers; thus, it is ....etc

ABSTRACT
• To optimize traffic anonymity protocol used in wireless networks.
EXISTING SYSTEM
• Suitable for wireless wide area networks
• Assumes multiple links in wide area networks.
• This makes easy for the adversary to identify the physical location of the sender and receiver and also their network identity.
PROPOSED SYSTEM
• To introduce an approach for Enhanced anonymous routing in broadcas ....etc

Privacy-Preserving Updates to Anonymous and Confidential Databases -
JAVA



ABSTRACT
Suppose Alice owns a k-anonymous database and needs to determine whether her database, when inserted with a
tuple owned by Bob, is still k-anonymous. Also, suppose that access to the database is strictly controlled, because
for example data are used for certain experiments that need to be maintained confidential. Clearly, allowing Alice
to directly read the contents of the tuple breaks the privacy of Bob (e.g., a patient’s medical record); on ....etc

Abstract

This is paper presents a complete view on working of payment transaction by E-cash. Cryptography used in this process finds the double spending and forgery of E-cash which is nothing but digital information. The digital information specified as E-cash contains the identity of buyer. Bank maintains all information involved in E-cash notes for every user.

The process of transaction involves three participants i.e, bank (who signs E-cash notes),buyer (who uses E-cash),seller(who deposits the notes). The cryptograph ....etc

1.Introduction
 Information protection
 When dealing with information protection, we must distinguish between security and dependability.
 Security can be defined in terms of confidentiality, availability,integrity and authenticity .
 Dependability mostly concerns the computing system.
 It can be described as a composite of availability (of a service), reliability (continuity of service) and maintainability (ability to undergo modifications and repairs)

Abstract—View is a labeled directed graph containing all information about the network that a party can learn by exchanging messages with its neighbors. View can be used to solve distributed problems on an anonymous network (i.e., a network that does not guarantee that every party has a unique identifier). This paper presents an algorithm that constructs views in a compressed form on an anonymous -party network of any topology in at most rounds with bit complexity, where the time complexity (i.e., the number of local computation steps pe ....etc
