Query: Security Algorithms for Cloud Computing Environment   In symmetric key cryptography the sender as well as the receiver possess a
common key. Asymmetric key cryptography involves generation of two distinct
keys which are used for encryption and decryption correspondingly. The sender
converts the original message to cipher text using the public key while the
receiver can decipher this using his private key. This is also called Public
Key Cryptography. For every public key there can exist only one private key
that can decipher the encrypted text. Security of RSA Algorithm can be
compromised using mathematical attack, by guessing the factors of a large
number. It may also be compromised if one can guess the private key. In
accordance with the mathematical attack, we propose a secure algorithm in this
paper. In this algorithm, we try to eliminate the distribution of n which is
the large number whose factors if found compromises the RSA algorithm. We also
present a comparative analysis of the proposed algorithm with the RSA
algorithm.
