Achieving Authentication and Integrity using Elliptic Curve Cryptography Architecture

Abstract

Communication security is one of the areas where research is highly required. The data used in communication is very sensitive and needs to be protected and made abstract from intruders of system. This research is all about securing the messages or data that is being communicated among two parties.The recent branch of Network security is Cryptography using Elliptic Curve Architectures which is based on the arithmetic of elliptic curves and discrete logarithmic problems. ECC schemes are public-key based mechanisms that provide encryption, digital signatures and key exchange algorithms. The best known encryption scheme is the Elliptic Curve Integrated Encryption Scheme (ECIES) which is included in IEEE and also in SECG SEC 1 standards. The key establishment protocol is Elliptic Curve MQV, with implicit certificates and symmetric key cryptographic techniques. The research focuses on achieving secrecy using ECIES algorithm for encryption, and authentication using Hashing technique. The hashed plaintext is again encrypted with RSA. At the receiver end, the hashed text is decrypted first. The hash value of the plaintext decrypted is compared with the latter hash. If they are found equal, the integrity can also be assured. The parameters to considered choosing Elliptic Curves are presented in NIST document of recommended elliptic curves.

Elliptic Curve Cryptosystem for Digital multimedia, General Review

“…The public blockchain in Bitcoin is a collection of everyday Bitcoin transactions. Every block in this group carries an SHA-256 hash of the previous block, therefore the chaining of blocks begins with the origin block [18]. Secure Shell (SSH) employs ECC for server/client selfauthentication by signing a replica of the exchange key, and ECDSA can be the key; clients can then use ECDSA as public keys for client authentication [18].…”

“…Cryptographic hardware modules are included in the smart cards, which carry a private key for encryption and signing. ECC has a smaller key size and lowers computational complexity [18]. The certificates of Transport Layer Security (TLS) consists of a kind of a public key in a way that the server uses to authenticate itself, and ECDSA can be that public key.…”

“…The certificates of Transport Layer Security (TLS) consists of a kind of a public key in a way that the server uses to authenticate itself, and ECDSA can be that public key. TLS included ECC in the client/server greeting messages as well as a new set of cypher suites [12], [18].…”

Data Security for Cloud Computing based on Elliptic Curve Integrated Encryption Scheme (ECIES) and Modified Identity based Cryptography (MIBC)

“…together. Hence it is called Integrated Encryption Scheme, since it is a hybrid scheme that uses a public key system to transport a session key for use by a symmetric cipher [15]. In ECIES, a Diffie-Hellman shared secret is used to derive two symmetric keys k1 and k2.…”
