【摘要】：隨著移動互聯(lián)網(wǎng)的快速發(fā)展以及智能終端設(shè)備的大范圍推廣,電子標(biāo)簽技術(shù)已經(jīng)逐漸在各行各業(yè)中廣泛運(yùn)用。二維碼作為一種信息的載體,同時也是信息搜集、數(shù)據(jù)存儲的重要方法和手段,已經(jīng)在物流管理、工業(yè)自動化和電子商務(wù)等領(lǐng)域得到了廣泛的應(yīng)用,然而隨之也產(chǎn)生了一系列信息安全問題,特別是在電子商務(wù)領(lǐng)域,如何防范二維碼信息被偽造或被篡改等問題,這已經(jīng)關(guān)系到每個使用者的切身利益。二維碼的安全性問題已成為世界領(lǐng)域?qū)＜覍W(xué)者研究的熱點(diǎn)課題之一。本文詳細(xì)分析了二維碼產(chǎn)生發(fā)展歷程、應(yīng)用領(lǐng)域以及面臨的安全性問題。研究了二維碼編解碼算法以及數(shù)字信息加解密算法。重點(diǎn)研究了 QR碼的編碼和解碼以及非對稱公鑰體系中的RSA算法。在此研究的基礎(chǔ)上提出了一種基于PKI技術(shù)的解決二維碼安全性問題的算法,該算法采用私鑰對二維碼信息加密,采用公鑰進(jìn)行解密,改變了傳統(tǒng)的PKI技術(shù)中公鑰加密私鑰解密的思想。該算法較好的解決了二維碼信息防篡改以及真?zhèn)舞b別等安全性問題。本文采用C#編程語言,設(shè)計(jì)實(shí)現(xiàn)了基于RSA的二維碼加解密應(yīng)用系統(tǒng)。該系統(tǒng)平臺包括公私鑰生成模塊、加解密密鑰管理模塊、二維碼設(shè)計(jì)與生成模塊以及二維碼識別和解密模塊。完成了 PKI公鑰體系中的CA認(rèn)證中心、服務(wù)提供商和用戶三種角色的功能。本算法的密鑰管理模塊中私鑰負(fù)責(zé)加密,而公鑰則負(fù)責(zé)解密。密鑰管理方案采用封閉式,這樣既解決了二維碼數(shù)據(jù)傳輸?shù)陌踩詥栴},又具有了身份認(rèn)證的功能,較好的解決了二維碼數(shù)據(jù)真?zhèn)舞b別問題。這種加解密模式更符合OTO電子商務(wù)模式的認(rèn)證識別。
[Abstract]:With the rapid development of mobile Internet and the wide spread of intelligent terminal devices, tag technology has been widely used in various industries. As a carrier of information, QR code is also a collection of information. The important methods and means of data storage have been widely used in the fields of logistics management, industrial automation and electronic commerce. However, a series of information security problems have emerged. Especially in the field of electronic commerce, how to prevent the information of QR code from being forged or tampered with. The security of QR codes has become one of the hot topics of experts and scholars in the world. In this paper, the development of QR codes is analyzed in detail. The application field and security problems are discussed. The encoding and decoding algorithm of two-dimensional code and the encryption and decryption algorithm of digital information are studied. The encoding and decoding of QR code and the RSA algorithm in asymmetric public key system. Based on this research, an algorithm to solve the security problem of QR code based on PKI technology is proposed. The algorithm uses the private key to encrypt the information of the two-dimensional code and decrypts the information with the public key. The idea of public key encryption and private key decryption in traditional PKI technology is changed. The algorithm solves the security problems such as anti-tampering and authenticity authentication of two-dimensional code information. C # programming language is used in this paper. The design and implementation of a two-dimensional code encryption and decryption application system based on RSA. The system platform includes public and private key generation module, encryption and decryption key management module. The design and generation module of two-dimensional code and the identification and decryption module of two-dimension code. The CA authentication center in PKI public key system is completed. In the key management module of this algorithm, the private key is encryption, and the public key is responsible for decryption. The key management scheme is closed. This not only solves the security problem of the data transmission of QR code, but also has the function of identity authentication. This encryption and decryption mode is more suitable for authentication and identification of OTO e-commerce mode.
