Abstract:The essence of electronic payment is the information of web-based flow of funds, which needs to be guarded against security risks. There is no information system (IS) security without cryptology. This study focuses on a variety of cryptography techniques including the traditional symmetric cryptography, asymmetric cryptography, password Cryptanalysis of Hash Ftmctions, as well as digital certificate and other cryptography techniques that is used among the financial community in electronic payments.
These cryptography techniques are used in electronic payments, ensuring the security of electronic transactions, and guarantee the integrity, confidentiality, reliability, non-repudiation and auditability of the transactions data.
This study has elaborated on the security of the techniques above.
Keywords:electronic payment  cryptology  symmetric cryptography  asymmetric cryptography  password cryptanalysis of Hash functions  online-banking
