Abstract: Internet banking has become one among the fastest and easiest ways of banking. The threat of cyber security attacks set a great challenge for the internet banking industries, where the security of our data has become a huge issue. This paper aims to describe a type of information attack or theft called salami slicing attack. In a nutshell, salami slicing attack occurs when a small piece of information is acquired from various sources in such a way that the victims whose information ware acquired from didn?t notice. So many researches were carried out till date to solve the issue of salami attack nevertheless all of them seem to be very unrealistic. Salami attack is correspondingly called penny splinter, not observed stealing (NoS). The remedy for this kind of attack is achieved by proposing homomorphic encryption. When the info is transferred to the general public area, there are many encryption algorithms to secure the operations and therefore the storage of the info. But to process data located on remote server and to preserve privacy, homomorphic encryption is beneficial that permits the operations on the cipher text, which may provide an equivalent results after calculations because the working directly on the data. In this paper, the most focus is on public key cryptographic algorithms supported homomorphic encryption scheme for preserving security.
