Enhancing Data Security in the Cloud using Security (RSA) Algorithm

Vishwanath S. Mahalle and Ritesh Satija


Security being the most important factor in cloud  computing  has  to  be  dealt  with  great precautions.  Thus  to  provide security to  the user  data  in  cloud  we  make  use  of  RSA algorithm. We have focused on following key tasks:  

1.  Secure Upload of data on cloud such that even the vendor is unaware of the contents.

2.  Secure  Download  of  data  in  such  a wa that   the   integrit of   data   is maintained.

3.  Proper usage and sharing of the public and private keys     involved          for encryption and decryption.

 The use of a single key for both encryption and  decryption  is  very  prone  to  malicious attacks. But in RSA, this problem is solved by the  use  of  two  separate  keys  one  each  for encryption as well as  decryption. Out of the two keys one is the public key, which is made available  to  all  and  the  second  one  is  the private key which lies only with the user. In this way, both the secure upload as well as secure download of the data is facilitated using the      two      respective    keys.     Also,    the       key generation  technique  used  in  this  project  is unique  in  its  own  way.  This  has  helped  in avoiding any chances of repeated or redundant key.
