Project Abstract

LIVE: Lightweight Integrity Verification and Content Access Control for Named Data Networking

 

ABSTRACT:-

 

            Named data networking (NDN) is a new paradigm for the future Internet wherein interest and data packets carry content names rather than the current IP paradigm of source and destination addresses. Security is built into NDN by embedding public key signature in each data packet to enable verification of authenticity and integrity of the content. However, existing heavyweight signature generation and verification algorithms prevent universal integrity verification among NDN nodes, which may result in content pollution and denial of service attacks. We propose a lightweight integrity verification (LIVE) architecture, an extension to the NDN protocol, to address these two issues seamlessly. LIVE enables universal content signature verification in NDN with lightweight signature generation and verification algorithms. Furthermore, it allows a content provider to control content access in NDN nodes by selectively distributing integrity verification tokens to authorized nodes.

EXISTING SYSTEM

PROPOSED SYSTEM

EXISTING CONCEPT:-

Existing process heavyweight signature generation and verification algorithms prevent universal integrity verification among NDN nodes, which may result in content pollution and denial of service attacks.

Heterogeneous network setting are only needed to achieve the same delay performance as the performance limit of any two-hop relay forwarding policy under its homogeneous counterpart.

 PROPOSED CONCEPT: -

We propose a lightweight integrity verification architecture (LIVE) that emphasizes controlling content access in NDN by leveraging content integrity verification.

We also analyze CPs’ security policies for content access in NDN nodes to ensure secure content access.

 

 EXISTING TECHNIQUE:-

Named data networking (NDN) Algorithm.

PROPOSED TECHNIQUE:-

Key Generation and Encryption algorithm.

 TECHNIQUE DEFINITION:-

Security mechanism in NDN with a minimal extension. Particularly, our design is based on the fact that the current NDN design requires a signature field in each content packet for content integrity verification.

Intuitively, NDN nodes, i.e., content routers and end users (devices), are willing to cache or consume a data packet only after its integrity is successfully verified, which means that the packet is not tampered or faked.

TECHNIQUE DEFINITION:-

The signing algorithm in LIVE performed by a CP. To generate a signature for a content, the CP needs to generate a new token key vector X and uses the hash algorithm to produce a new token.

The signature verification algorithm performed in an NDN node, which is similar to the signing algorithm.

The NDN node computes the bit vector g with the MHT algorithm according to the received content and the token.

 

DRAWBACKS:-

Traditional signature schemes, it is not easy to revoke public keys so that it may not be possible to revoke content verification permissions assigned to content routers or users at run time.

Existing security mechanism in NDN with a minimal extension.

ADVANTAGES:-

Simple integrity verification in LIVE.

We seek to address efficient integrity verification and content access (including caching) control with a single solution in the network layer.
