CLOUD COMPUTING

INTRODUCTION
An emerging computer paradigm where data and services reside in massively scalable data centers in the cloud and can be accessed from any connected devices over the internet.
It is a computing industry where the computing is moved to a cloud of computers.

source code for homomorphic encryption in matlab

The idea of an homomorphic encryption scheme is not a new one.

Already one year after the introduction of RSA (the first public key encryption scheme discovered by the scientific community) it was noticed that RSA had the special property that if you multiply two ciphertexts together, then the resulting value would be a valid encryption of the product of the original plaintexts! In other words, by manipulating the ciphertexts (the random looking strings containing your data) you are manipulatin ....etc

Network coding has been shown to optimally use bandwidth in a network, maximizing information flow but the scheme is very inherently vulnerable to pollution attacks by malicious nodes in the network. A node injecting garbage can quickly affect many receivers. The pollution of network packets spreads quickly since the output of (even an) honest node is corrupted if at least one of the incoming packets is corrupted. An attacker can easily corrupt a packet even if it is encrypted by either forging the signature or by producing a collision under th ....etc

Abstract

Homomorphic encryption is a form of encryption that allows computations to be carried out on ciphertext, thus generating an encrypted result which, when decrypted, matches the result of operations performed on the plaintext.

This is sometimes a desirable feature in modern communication system architectures. Homomorphic encryption would allow the chaining together of different services without exposing the data to each of those services. For example, a chain of different services from different companies could calculate

Homomorphic Linear Authentication Schemes for Proofs of Retrievability

In a proof of retrievability (POR) system, interactive POR protocols are executed between a storage server and clients, so that clients can be convinced that their data is available at the storage server, ready to be retrieved when needed. In an interactive POR protocol, clients initiate challenges to the server, and the server feedbacks responses to clients with input of the stored data. Retrievability means that it should be possible for a client to extract the his/her ....etc

Healthcare, financial, government, and military organizations depend on encryption to secure sensitive data. Historically, this data has had to be decrypted before it could be processed or analyzed. As a result, data processing had to be performed on secured hardware, eliminating the possibility of using the cloud or other low-cost, third-party computing resources.

At the Symposium on the Theory of Computing in 2009, Craig Gentry of IBM presented a fully homomorphic encryption (FHE) scheme that made it possible to send sensitive data to an uns ....etc
