Abstract: Data security is an important issue in current scenario of banking financial operation specially with transaction of secure and confidential data. It must be send with high security at the time of communication. In this paper we will discuss various types of encryption methods and standards which are used in secure banking data transmissions to make more data security. Specially here we discuss the communication security methods used between Auto teller machine and bank server banking financial operations, When we transmit data from an Auto Teller Machine to bank server it must send in encrypted form so that an unauthorized user cannot access the secure information directly at the time of data communication. using this paper I will try to explain different data security that how the data transactions can make more secure with different security techniques used in ATM transactions. Various security levels of data and encryption standard used in banking data transaction security. Encryption methods are built into the communication network to prevent unauthorized transactions that could protect the data from unauthorized access. This paper focuses on Data Encryption Standard and Advanced Encryption Standard, these are the encryption standards used by the banks to protect the data and for secure data transmission.
