    Elliptic Curve Cryptology What and Why of ECC? Elliptic curve cryptography (ECC) is a public key cryptography technique by making use of elliptic curve properties and their algebraic structure of over finite fields. It is one of the efficient ways of providing encryption of cryptographic keys. Elliptic curves as algebraic/geometric entities have been studied extensively for the past 150 years, and from these studies has emerged a rich and deep theory. Elliptic curve systems as applied to cryptography

    encryption: when Alice wishes to send a message to Bob, she looks up Bob's public key in a directory, uses it to encrypt the message and sends it off. Bob then uses his private key to decrypt the message and read it. No one listening in can decrypt the message. Anyone can send an encrypted message to Bob but only Bob can read it. Clearly, one requirement is that no one can figure out the private key from the corresponding public key. Here's how it works for authentication: Alice, to sign a message

In addition the secret key needs to have some simple, exploitable relationship with the operations that are visible in the measurement trace. Finally typically, vulnerable implementations include key dependent branching. Differential Side Channel Analysis: It looks for side channel differences that are not directly visible in one measurement trace. The statistical methods have to

First Alice will generate a random challenge, C1, to send to Carol. Carol will compute a message digest of the challenge C1 and the shared key KAC, and reply to Alice. Carol will also send another challenge, C2, to Alice. Alice will do the same thing with C2 and KAC, and send the response to Carol. When each recipient receives

    TOR Onion routing (Syverson) is an anonymous communication technique used to anonymize network traffic. Messages are encrypted recursively and sent to multiple network nodes or onion routers; each router decrypts one layer of the message and passes it on to the next router. This prevents the transport medium to find out who you are; the network does know that onion communication is taking place.

    Homomorphic Encryption allows access to highly scalable, inexpensive, on-demand computing resources that can execute the code and store the data that are provided to them. This aspect, known as data outsourced computation is very attractive, as it alleviates most of the burden on IT services from the consumer. Nevertheless, the adoption of data outsourced computation by business has a major obstacle, since the data owner does not want to allow the un trusted cloud provider to have access to the data
