Based On Banking Data Encryption Technology For Interactive Systems Design And Implementation

This dissertation describes the related techniques about bank system encryption and digital signature,exhibits the integrated process of the detailed implementation.With the development of the financial industry, the data exchange in bank system is more and more frequent.Especially refer to the data exchange among banks.The data during the transaction among banks is very valuable and confidential.We must make sure the security of the transaction and no probability of stealing.To solve the conflict of high requirement of data exchange and high possibility of security issues,it is much practical and worth studying the security of bank systems.This thesis simulates requesting digital certificates and fetching the certificate for two banks to establish their trust of each other by GUI instead of manual manipulate through keytool and certificate authority.With the issued certificate,a report which is from a branch bank to central bank,is encrypted with Blowfish ECB symmetric arithmetic, RSA public key crypto and SHA hashing for digital signature at the side of branch Bank;then at the central bank side,the report is decrypted with the correspondent arithmetic and keys.This process ensures high security in data transfer processes among banks.This dissertation focuses on implementing two major points of CA provided by Microsoft and Oracle,and the encryption and digital signature procedures with special arithmetic applicable to bank system.
