| Abstract: | PPPoE’s principles of work and its two kinds of safety threats are briefly elaborated.Taking advantage of the legal host and legal access concentrator with the property of their own specific user name and its password,and also with the help of HMAC algorithm,the program advanced in the article constructs a two-way authentication process on the basis of challenge and response.A practical PPPoE program for security improvement is given,and a thorough analysis is also given. |
