Embodiment 1

[0029] As shown in Figure 2, the mobile phone 1 of the present invention that realizes electronic signature has mobile phone card 5 (SIM or UIM card etc.), and this mobile phone card 5 belongs to the owner of this mobile phone 1 exclusively, and when carrying out electronic signature, the owner People can use the signature program to electronically sign the signature file according to the key, the pre-stored STK program, and the digital certificate representing the identity of the mobile phone owner. After signing, any changes to the content and form of the signature file and the electronic signature Therefore, the electronic signature complies with the requirements of reliable electronic signatures in the Electronic Signature Law, and has the same legal effect as handwritten signatures and seals.

[0030] Wherein, the digital certificate is provided by an electronic certification service provider (such as a CA, not shown), and the electronic certification service provider has ...

Embodiment 2

[0035] The mobile phone of embodiment 2 of the present invention also has the same structure as shown in Figure 1, and when carrying out electronic signature, this owner can according to electronic seal, the STK program of pre-stored and the digital certificate representing mobile phone owner's identity, to After signing, any changes to the content and form of the signature document and the electronic signature can be found, so that the electronic signature complies with the requirements of reliable electronic signatures in the Electronic Signature Law, and has the same characteristics as handwritten signatures. It has the same legal effect as stamping.

[0036] An electronic seal is prestored in the mobile phone card 5, and the electronic seal corresponds to the digital certificate. The mobile phone reads the electronic seal through the APDU (Application Protocol Data Unit) protocol, and utilizes the electronic seal to realize the electronic signature of the signature file. ...

Embodiment 3

[0039]

[0040] FIG. 2 shows a schematic diagram of an electronic signature system according to Embodiment 3 of the present invention. The electronic signature system utilizes the SIM or UIM card of the mobile phone in Embodiment 1 to implement a symmetrically encrypted electronic signature.

[0041] As shown in FIG. 2 , the electronic signature system includes a signatory's mobile phone 1 , an electronic authentication service provider (not shown), a server 2 and a client 3 . Wherein, the mobile phone 1 has been authenticated by the electronic authentication service provider as described in Embodiment 1, and has a digital certificate.

[0042] Key K is pre-installed on the mobile phone card 5 (SIM or UIM card) in the mobile phone 1, and this mobile phone card 5 can realize the function of the application program Applet that adopts Java program writing. At the same time, the key K with the same content is also pre-installed on the server 2, and the same two keys are protecte...

Abstract

Based on STK program and digit certificate, which represents identity of owner of mobile terminal, the mobile terminal carries out electronic signature for signature file. Being accorded with stipulation of electronic signature raw, electronic signature possesses force of law identical to handwritten signature and stamp.

Description

technical field [0001] The present invention relates to an electronic signature mobile terminal, system and method, in particular to an electronic signature mobile terminal, system and method for realizing symmetric or asymmetric encryption by using a mobile terminal ID card of the mobile terminal. Background technique [0002] Many traditional electronic signatures use the PKI system, that is, public key infrastructure = Public-KeyInfrastructure), which is a combination of public key cryptography and symmetric cryptography, and realizes automatic key management on the Internet to ensure the security of online data. The mechanism of transmission. PKI uses public key technology and digital certificates to ensure system information security and is responsible for verifying the identity of digital certificate holders. [0003] PKI uses the same certification authority (Certification Authority, CA) that all participants trust, and the CA uses digital certificate application sof...
