The Research Of SIM Card Dignity Attestation System Based On OMS Mobile Terminal

As more and more extensive use of smart phones, mobile phone access to the Internet, play online games, buy merchandise, pay fees, such as mobile phones become a popular and convenient services, the trend and needs.In order to ensure that the property can only be the users have the legal authority to ensure the accuracy and reliability of service providers to ensure information security, the arrival of the recipient, and so all of this,an urgent need for a way to provide security services for mobile terminals.The authentication service is the first line of security services in the field of information security has an important significance.Now commonly used authentication method there are various enough, or not enough security, such as username/password approach; or expensive, such as a fingerprint identification; or not conducive to use in public places, such as digital certificates;or upon issuance, no change orupgrades, such as USB-key; more can not be applied to mobile terminals.The same time, although the existing mobile terminals in terms of security advantages and disadvantages, but there is a common problem, identity information can be lost because of cell phones stolen.This article address this issue,which is based on PKI-SIM card authentication technology.The technology will be PKI-SIM card as the user private key of the carrier, providing the hardware level of the private key data confidentiality, and the card to achieve a variety of security algorithms, there is sufficient security measures to ensure the integrity of the key.And this authentication technology in the mobile terminal to achieve, has designed a mobile platform based on safety programs and to achieve the program.To address the mobile Internet end to end security issues. Paper first analyzes the current status of mobile terminals, as well as the safety of people's needs, indicating the provision of security services, the need for mobile terminals.In this mobile phone platform based on the authentication system OMS program,and designed overall system architecture diagram.Secondly, the paper gives the mobile phone platform authentication system OMS application modules, memory modules, the detailed functional design and protocol design.Including the landing of software securit applications, functional design, protocol design.Memory modules in the key safety management protocol design.Then the authors OMS security applications on the mobile phone operating system, the development of in-depth study and practice to achieve the program's core functions.Finally,the author will use the OMS mobile platform identity authentication system for mobile terminals and are not using the system to compare the mobile terminal to verify the practicality and superiority of the program and pointed out the inadequacy of the program.
