Data Security Architecture in Cloud Computing based on Elliptic Curve Cryptography with Special Focus on Lowering the Cipher Space

Public key Cryptography which is associated with pair of public and private keys is an important requirement for electronic commence in the history of cryptography. Since public key is shared it should be digitally stored in the software in the form of public key Infrastructure (PKI) certificates Elliptic Curve Cryptography plays major role in cloud computing due to the exceptional property of smaller key size. ECC has wide range of applications in Secure Socket Layers (SSL) of cloud computing. The main disadvantage of ECC is the cipher space is two times the message. The present paper explains an innovative elliptic curve cryptosystem that reduces the cipher space, equal to the original message
