【摘要】：現(xiàn)階段3G(第三代移動(dòng)通訊技術(shù))和Wi-Fi無(wú)線網(wǎng)絡(luò)技術(shù)已經(jīng)發(fā)展到普及的程度,4G(第四代移動(dòng)通訊技術(shù))也開始進(jìn)入人們生活,人們使用智能手機(jī)甚至超過(guò)了使用個(gè)人PC；智能手機(jī)已經(jīng)成為個(gè)人、家庭、企業(yè)的必不可少工具,這使得智能手機(jī)承載的數(shù)據(jù)涉及到了生活、教育、醫(yī)療、交通、商業(yè)等眾多領(lǐng)域,關(guān)系到了人們的隱私和安全。以Android系統(tǒng)為平臺(tái)的手機(jī)已經(jīng)占據(jù)了國(guó)內(nèi)市場(chǎng)主導(dǎo)地位,所以研究針對(duì)Android平臺(tái)的數(shù)據(jù)保護(hù)問題具有普遍的實(shí)用價(jià)值和一定的理論意義。 本文旨在設(shè)計(jì)和實(shí)現(xiàn)一個(gè)基于云計(jì)算平臺(tái)的Android智能手機(jī)數(shù)據(jù)保護(hù)的應(yīng)用,提高數(shù)據(jù)的安全系數(shù),防止數(shù)據(jù)丟失和敏感數(shù)據(jù)泄密。 針對(duì)現(xiàn)階段Android智能手機(jī)的數(shù)據(jù)安全狀況,在研究了Android平臺(tái)及其開發(fā)關(guān)鍵技術(shù)、移動(dòng)平臺(tái)信息安全技術(shù)、備份策略、加密解密技術(shù)、云計(jì)算技術(shù)的基礎(chǔ)上,采用面向?qū)ο蟮乃枷牒图夹g(shù)進(jìn)行了系統(tǒng)的可行性分析、需求分析、概要設(shè)計(jì)、詳細(xì)設(shè)計(jì)和實(shí)現(xiàn)。系統(tǒng)結(jié)合云計(jì)算和移動(dòng)計(jì)算兩大熱門技術(shù),針對(duì)手機(jī)丟失或被盜對(duì)敏感數(shù)據(jù)的威脅這一情況,提出了一套基于云計(jì)算平臺(tái)的數(shù)據(jù)保護(hù)安全方案,客戶端將數(shù)據(jù)采用高效的最新加密標(biāo)準(zhǔn)算法AES加密后備份到云端,獲取云端數(shù)據(jù)后解密恢復(fù),被保護(hù)的數(shù)據(jù)是用戶私有數(shù)據(jù)如通訊錄、短信息錄、圖片、文本等；當(dāng)手機(jī)處于危險(xiǎn)狀態(tài)時(shí)如丟失、被盜,及時(shí)改變手機(jī)狀態(tài)并發(fā)送數(shù)據(jù)刪除指令,實(shí)現(xiàn)遠(yuǎn)程刪除手機(jī)被保護(hù)數(shù)據(jù)的功能,達(dá)到保護(hù)個(gè)人數(shù)據(jù)的可用性、完整性、保密性的目的。最后介紹了系統(tǒng)測(cè)試的硬件、軟件環(huán)境和測(cè)試用例,并進(jìn)行了真機(jī)測(cè)試,并針對(duì)測(cè)試結(jié)果的分析提出了改進(jìn)方向。實(shí)驗(yàn)證明該系統(tǒng)滿足了提出的需求,一定程度上解決了移動(dòng)數(shù)據(jù)的安全威脅問題,對(duì)以后移動(dòng)平臺(tái)數(shù)據(jù)安全方面的研究也具有指導(dǎo)意義。
[Abstract]:At this stage, 3G (third generation mobile communication technology) and Wi-Fi wireless network technology have developed to the extent of popularization. 4G (fourth generation mobile communication technology) has also begun to enter people's lives. People use smartphones more than personal PCs; smartphones have become essential tools for individuals, families, and businesses, so that smartphones carry data about life, education, health care, transportation, Business and many other fields, related to people's privacy and security. The mobile phone with Android system as the platform has already occupied the dominant position in the domestic market, so it is of universal practical value and certain theoretical significance to study the data protection problem of the Android platform. The purpose of this paper is to design and implement an application of Android smart phone data protection based on cloud computing platform, to improve the safety factor of data, and to prevent data loss and sensitive data leakage. In view of the current data security of Android smart phone, this paper studies the key technologies of Android platform and its development, mobile platform information security technology, backup strategy, encryption and decryption technology, cloud computing technology. The feasibility analysis, requirement analysis, outline design, detailed design and implementation of the system are carried out by using object-oriented thought and technology. Combining two popular technologies of cloud computing and mobile computing, the system proposes a data protection security scheme based on cloud computing platform in view of the threat to sensitive data caused by the loss or theft of mobile phones. The client uses the new encryption standard algorithm AES to backup the data to the cloud and decrypts and recovers the data. The protected data is private data such as address book, short message book, picture, text and so on. When the mobile phone is in a dangerous state, if it is lost or stolen, it can change the status of the mobile phone and send the data deletion instruction in time, so as to realize the function of remotely deleting the protected data of the mobile phone, and achieve the purpose of protecting the availability, integrity and confidentiality of personal data. Finally, the hardware, software environment and test cases of the system test are introduced, and the real computer test is carried out, and the improvement direction is put forward for the analysis of the test results. Experiments show that the system can meet the requirements and solve the security threat of mobile data to a certain extent. It also has a guiding significance for the future research on data security of mobile platform.
