Dynamic mobile signature system and method

Abstract

The invention discloses a dynamic mobile signature system and method. An improvement is conducted on the software and hardware environment of a mobile terminal, so that the dynamic encryption process and the dynamic decryption process are achieved. The mobile terminal is made to conduct dynamic signature on trade data sent to a commercial tenant through data interaction between a cloud dynamic signature service platform and the mobile terminal and data interaction between the cloud dynamic signature service platform and a commercial tenant platform, then, the trade data are sent to the commercial tenant platform through the cloud dynamic signature service platform to be confirmed after the signature is authenticated, and the operation of mobile payment is permitted according to trade information confirmed by a commercial tenant, wherein the cloud dynamic signature service platform and the mobile terminal are connected through the internet. By means of the dynamic mobile signature scheme, the defects of the hardware signature are overcome, the dynamic signature authentication at the software level is achieved, safety and flexibility of the mobile terminal are greatly improved when the mobile terminal participates in electronic commerce trade information confirming, the signature and authentication process is produced through a dynamic signature algorithm which is unceasingly updated on the basis of a cloud server, and therefore invasion of Trojan horse viruses can be effectively resisted, and safety performance of information confirming can be improved.

Description

technical field [0001] The invention relates to an information security authentication technology of a mobile terminal, which is realized by comprehensively utilizing computer, network server, information coding and mobile communication technology, and can be applied to the mobile terminal to perform information confirmation on money exchanges or application server login, etc. The system and field of identity confirmation specifically relate to a dynamic mobile signature system and its implementation method. Background technique [0002] In November 2007, Google released Android, a software platform for smart terminals. Over the past five years, the Android system has rapidly become the most widely used platform for mobile smart devices with its technical features such as high efficiency, open source, and easy expansion. However, in recent years, malicious codes have spread rapidly along with the market expansion of the Android system, and the security problems exposed in t...

Problems solved by technology

[0006] The reason is that the previous transaction confirmation method was too simple and fixed. In addition to the risk in the password acquisition process of this kind of password authentication method, the hardware and software programs of the password authentication are relatively fixed, which are easy to be hijacked, damaged and rewritten. Even if the online banking U-shield Regularly updating the so-called drivers cannot avoid the bad luck of being hijacked. The above-mentioned methods of hardware encryption and verification can no longer adapt to the current trend and needs of the rapid development of e-commerce
