Abstract: - Shared data systems have grown in numbers and hence they are susceptible to many security challenges. The sender embeds a plain message in another plain text called Cheating Text. The positions of the characters of the plain text in the cheating text are stored in a Real Message Index File (RIF).This file is encrypted using Nth degree truncated polynomial ring (NTRU) scheme and sent along with the cheating text. The receiver once received, proceeds to decrypt the RIF table and gets back the original message from the received cheating text. Authentication to decrypt is achieved by NTRU key exchanges prior to session initiation at both senders and receivers side along with the MD5 hash of the RIF. An NTRU 263-bit encryption key, has cryptographic strength equivalent to renowned powerful 1024-bit RSA key. We propose to replace any secure Scheme with a more robust NTRU crypto system.
