The network system security has become one of the most popular issues concerned by the masses of users on the Internet.To telecom operators,vast amounts of customer information let them make a lot of profit by analyzing the user data.But while they improve the service efficiency and income,all kinds of safety problems also appear constantly.The key to protect information security is the technique level and the user's experience degrees,and it depends on the system security.As a result,an telecom operator's BSS system as an example,this paper put forward the improved mind of the algorithm about the resistance of collision by analyzing the existing risk on security of the BSS system,summarizing the requirements of the system security,depending on the advantage and disadvantage of the MD5.It proves the advantages of the advanced algorithm through the comparison with the 3DES and the SHA-1.It reduces the risk of the permissions violated through combination with login security mechanism,provides the safety ensurance of the BSS system security. |
