Computer network safe input authentication system and method

Abstract

The invention discloses a computer network safety attestation system and method that comprises terminal computer and network server, the input equipment of the terminal computer includes input unit (4) and interface unit (5), said terminal computer also includes control unit (1) and safe unit (2); the safe unit (2) receives the data input from the input unit (4) in safe inputting mode, encrypting data input with symmetry arithmetic by key, temporary key is encrypted and underwritten by the server general key transmitted by the network server with asymmetric arithmetic; said network server includes encrypting and deciphering unit(7); the encrypting and deciphering unit(7) deciphers the data package transmitted from the terminal computer with corresponding asymmetric arithmetic using server private key to obtain the key, validating the validity of temporary key, then the encrypted character string is deciphered with corresponding symmetry arithmetic using the temporary key to obtain data input by user. The inventions can guarantees the input data of computer not be filched, decrypted or forged.

Description

technical field [0001] The invention relates to the field of computer network security authentication, in particular to a computer network security input system and method. Background technique [0002] With the development of the network, users are using more and more applications on the network, such as mail, games, and online banking. For safety, these applications require users to input characters from input devices for network security authentication such as user identity. [0003] During computer use, users often input sensitive information such as user names, passwords, or transaction data through the network. During the operation of the network, a personal computer (PC) as an input terminal device accepts sensitive information such as user names, close friends, or transaction data input by users, and transmits them to the network server without processing or preliminary processing. The real data processing on the network server may also need to exchange data with ot...

Problems solved by technology

But the defect of this method is that on the one hand, the user needs to generate and read the input, which is very inconvenient to use; password entered

But this method only uses the symmetric key security authentication method, and in order to solve the symmetric key exchange problem, a constant is used to generate the key initially, so that other programs need to know this constant in order to generate related passwords, so that any first All three parties can obtain this constant, and can combine other technologies to obtain the key to decrypt the encrypted input content
