Research On Anti-phishing Mechanisms Based On Active Encryption Technology

With the rapid development of the computer industry and the rapid improvement of the Internet technology,the data in the network and hard disk is showing a growth spurt,which makes the collection,storage and exchange of information more convenient and faster than before.At the same time,due to the rapid growth of electronic information,the security issue of the electronic data information is also increasingly prominent,and this problem is also a serious threat to the national security and the interests of individuals.Therefore,it is a profound significance for the individual citizens,business interests,and even national security that research on the anti-phishing mechanism of electronic data information.This article is about a research on the active encryption technology and anti-phishing mechanism which is used to protect the electronic data information,and this research is based on the file filter driver technology,eventually formed an electronic data protection technology which is based on file system filter driver technology and active encrypted technology.This technique is mainly used in the Windows kernel level,and it is used for transparent encryption,decryption and access control in the file filter layer for the secret electronic information.Meanwhile,the secret text data files are given the secret document identification,and these classified documents proactive identifications are added in the end of the file,which makes electronic documents and secret identification be bound together,eliminating the need for separate storing and managing the secret identification,and in this way,it can be quickly and easily to match these information.In the exchange between the secret and non-secret electronic document,in order to ensure the security of classified information,the subject mainly uses the SSDT HOOK technology to complete the infection and transmission of the secret state among processes,and eventually realizes the active encryption of the classified documents.This subject also uses an improved chaotic encryption algorithm to encrypt the classified documents.This subject has made the improvement to the "traditional single chaotic Logistic sequence encryption algorithm" and generates a new algorithm which is called "Improved composite Logistic chaotic sequence encryption algorithm".Compared with the traditional chaotic encryption algorithm,this algorithm overcomes the issue of the degradation of chaotic dynamic characteristics which is caused by the limit of the accuracy of equipment,and using this algorithm,the accuracy of encryption can be improved significantly and the classified electronic information can be protected in a large extent.
