The Considerable Security Issues on the Security Enforcement of Cryptographic Technology in Finance Fields

By known attacks against cryptographic technology and decline of security, internal and external major institutions have defined their recommendations in kinds, expiration, safe parameters of cryptographic technology and so on. Internal financial fields will change some cryptographic technology to follow these recommendations. To keep strong security of financial systems against sudden security changes of cryptographic technology, this article finds pre-steps : status of applied cryptographic technology, selection of vulnerable cryptographic technology.
