Electronic ticket service system and realizing method thereof

Abstract

The invention discloses an electronic ticket service system and a realizing method thereof. The method comprises the following steps of: generating electronic ticket surface information by a ticket service server; generating electronic ticket verification codes, encrypting the electronic ticket surface information and the electronic ticket verification codes into first ciphertext and transmittingto a ticket-drawing terminal in a safe mode by an electronic ticket authentification server; transferring the first ciphertext to an electronic ticket smart card by the ticket-drawing terminal; and receiving and decrypting the first ciphertext to acquire and store the electronic ticket surface information and the verification code by the electronic ticket smart card. The system and the method adopt a mode that the electronic ticket surface information which is generated by the ticket service server and the verification codes which is generated by the electronic ticket authentification server are safely transmitted to the ticket-drawing terminal, transferred in a ciphertext mode to the electronic ticket smart card and stored in the electronic ticket smart card, and the electronization, theverifiability, the accurate transmission, the safe storage and the copy protection of tickets and the record electronization of ticket use information are realized.

Description

technical field [0001] The invention relates to the field of smart cards and information security, in particular to an electronic ticket service system and its realization method. technical background [0002] Modern cryptography is divided into two categories according to the characteristics of the key: symmetric cryptography and asymmetric cryptography. Among them, the symmetric encryption technology is that the decryption key and the encryption key are the same. In this system, the distribution of the key is a difficult point in the application. Asymmetric cryptography is also called public key cryptography. In the public key cryptography system, the user has two keys, one is the public key and the other is the user's private key. Among the two keys, it is difficult to derive Another key. Therefore, both communicating parties can establish secure communication without exchanging keys in advance. [0003] There is a problem in the public key system: how to effectively c...

Problems solved by technology

[0003] There is a problem in the public key system: how to effectively correspond the user's public key with the user's identity

Such a system has a natural password delegation function, which is suitable for a supervised application environment, but cannot realize the verification of user identity

[0005] Existing smart cards, generally based on symmetric cryptography, are widely used, such as the China Financial Integrated Circuit smart card, but this smart card can only support a prepaid or postpaid service certificate of the same operator / service provider
