Analysis and Countermeasures of Network Security LiuBingyao Abstract This article is concerned about network security. It mentions about the present situation of network security and an analysis of the reason that lead to unsafe network environment. Then the article introduces two frequently used protocols in network security: HTTP (Hypertext Transport Protocol) and HTTPS (Hypertext Transfer Protocol over Secure Socket Layer)‚ then compare them and give a brief conclusion. On the other side

CRYPTOGRAPHY- ENCRYPTION AND DECRYPTION Cryptography is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally‚ it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality‚ integrity‚ authentication‚ and non-repudiation. Modern cryptography intersects the disciplines of mathematics‚ computer science
