Extension of Sts Protocol on Elliptic Curve Diffie-Hellman to Reduce Man-in-the-Middle Attack
Cloud computing offers an efficient and economic solution for sharing resources among different cloud users.
Yet, data sharing in a multi-owner manner and simultaneously preserving data and privacy in untrusted cloud is challenging.
Therefore, this paper proposed a mutual authentication among Multi-Owners and also minimizes the execution time and
finally improves security level against the cryptography attacks by using Diffie-Hellman key exchange protocol, Elliptic
Curve Digital Signature Algorithm. To prevent owners against Man-in-the-Middle attack the Station to Station Protocol is
used in proposed technology along with Elliptic Curve Diffie-Hellman algorithm. The ECDSA (Elliptic Curve Digital
Signature) algorithm is used for making signature and verifying signature. Our proposed algorithm ECDH with STS
improves authentication and data privacy on Multi-owner cloud.
