SUNXiuxian，DONG Huijuan （Jining senior vocational school， Jining 272ooo，China）

Abstract： at present， network atacks are increasingly frequent，and the use of data encryption technology can effectivelyresist theriskof network atacks.In view ofthis，this paper proposes asetoffeasible encryption technology for the data security problem in thecomputer network data transmission.Atthesame time，inorder torealize the evaluation of network securitythreats，AES and other encryption schemes are selected forapplication testing.Through the test and verification，the effectiveness of using AES-128 encryption algorithm to ensure the security of data transmissionisconfirmed.It is hoped thatthisresearch workcanprovide efective technicalsupportforthesecurityof computer network data transmission.
