A NOVEL SECURITY MECHANISM FOR HYBRID ENCRYPTION IN MINERAL MANAGEMENT INFORMATION SYSTEM
To increase the tax collection of mineral resources and enhance the management of resource exploitation, computerized mineral management information systems (MMIS) are developed and applied to the government management system. The MMIS are run at checking portals that inspect trucks transporting minerals. Only the trucks with the special permit (also called ticket) can pass through the checking portal after the ticket is correctly authenticated by the MMIS. Due to the huge economic benefits of the special tickets, the tickets are frequently fabricated. Because tickets are exoteric and current, the security of them becomes an urgent problem. In this paper, a novel security mechanism is proposed for the mineral management information system, in which the hash function, AES (Advanced Encryption Standard) encryption algorithm and ECC (Elliptic Curve Cryptography) encryption algorithm are hybrid to encode and encrypt the data involved with the ticket according to different sensitivity levels. Data are dynamically and separately stored into the disk storage or RFID (Radio Frequency Identification) tags storage. Identity authentication of the ticket is achieved by data in the two-dimensional bar code printed on the ticket, the RFID tag that is installed on the truck with the ticket, and the disk storage of MMIS database. MMIS equipped with the presented ticket encryption mechanism is secure and results in great economic and society interests.
