The invention discloses a method for saving and/or acquiring authentication parameters on terminal network equipment. When saving the authentication parameters on the terminal network equipment, a user terminal calculates the encrypted authentication parameters to produce a first identifying code; while acquiring the authentication parameters from the terminal network equipment, the terminal network equipment calculates the pre-saved encrypted authentication parameters to produce a second identifying code and compares the first identifying code with the second identifying code; the terminal network equipment sends the encrypted authentication parameters to the user terminal only when the two codes are the same. Accordingly, the invention also discloses a system for saving and/or acquiring authentication parameters on the terminal network equipment. Thereby, the invention avoids the criminal to obtain authentication parameters if the criminal doesn't get the identifying codes at the same after the terminal net
