Figure 1C shows a block diagram of the system 100, wherein the non-volatile memory device 105 The host system is interfaced via a USB interface. The non-volatile memory device 105 is authenticated by a remote server 1丨4 before allowing the user to use the non-volatile brother device. In one embodiment, the non-volatile memory device 1〇5 conforms to the USB specification (ie, the non-volatile memory 105 can be accessed via a uSB interface). A standard USB-based application design interface can be used (Ap </ br> to read or write data. In the view of the host 100, the non-volatile memory device 1 具有 5 has a plurality of logical units (LUNs) with storage space, and each LUN can be a different type of storage device For example, the non-volatile memory device 1〇5 can have a standard mass storage category volume (LUN 0, 107A) (the analog 8 (: 81 hard disk drive behavior) and one MMC category volume (LUN) 1, i〇7B) (which simulates the behavior of CD-ROM) LUN 1 107B can store a plurality of software applications (116, FIG. 1), one of the operating systems, a minimum version (Micro-OS) (l 1 5, figure ID), for a virtual engine (120, FIG. 1D) The code, and other information, as discussed below, is discussed in Figure 1D.

The overall operation of the non-volatile memory device 105 is controlled and executed by the controller 1〇6.

Micro-OS 115 is the smallest version of an operating system, i.e., has a reduced functionality compared to a standard operating system. Micr〇_〇s ιΐ5 is used to control the overall environment in which the code for a virtual engine is executed. The MiCro_〇S 115 can be customized to execute the code for the virtual engine, as described below. The Micro-OS can be stored in the read-only section 1〇76 (Fig. (1)). Application II6 is a software application that users can want to execute on different hardware/software platforms. More than one application 116 can be stored in the non-volatile memory device 105. The application 116 can include a web browser (e.g., Firef(R)/) that the user uses to browse the website. The web browser can be executed on any computer connected to the Internet 128115.doc 200837630 network. The web browser receives the request and sends it to a web server, and obtains information from the World Wide Web (www) (the computer's network). The web server is a program, and after receiving a request, the information of the (4) request is sent to a requesting user. The virtual engine (or virtual machine) (VE) 120 includes a private code for providing a virtual environment. The virtual environment provides a software platform that is independent of the host operating system. The code executed in the virtual environment is not controlled by the host operating system and is controlled by a virtual operating system executing within the virtual environment. The VE 120 also includes executable code for different operating systems executing in a virtual environment independent of the base host operating system. Micr〇_〇s ιΐ5 controls the overall execution of the VE 120. The code blocks for different operating systems are shown as V〇s 1, yog], VOS3, and VOSn. VOS1 can be used to implement the operating system of the base KWind〇ws8, VOS2 can be used for the Linux operating system, and v〇S2 can be used for operating systems based on υκ[χ. The operating system specific code (v〇sl to v〇s (2) is executed in a virtual environment independent of the operating system of the host system 100. The ve 120 allows the user to use the non-volatile memory device 105 on different hardware/software platforms. Different types of virtual engines can be used to implement the adaptive aspects of the present disclosure. For example, VMWare Player and VMWare Ace available from VMware c〇rp〇rati〇n can be used; available from Micros〇ft

Virtualpc and others purchased by Corporation. It should be noted that more than one virtual engine can be stored and used for application execution. This will make it difficult for illegal infringers to break into the operating system, because viruses or other destructive software will need to be connected to 128115.doc •14- 200837630 for two or more virtual engines instead of one virtual engine. Low level support. During the authentication phase, the non-volatile memory device 1 〇 5 uses device authentication 11 8 as described below. Security key 119 can be used to generate a password to authenticate a user/device. Using standard or proprietary encryption techniques, encryption engine 1 〇 6a can use secure key 119 to encrypt the stored content. A virtual private network (VPN) code 121 is provided to facilitate VPN connections, as described below. Restrict access to the VPN code 121 (by being stored in ίυΝ 1 (107B), Figure 1C) to make it difficult to illegally reprint or break into a virtual connection. Note for multiple software components (Micro-〇S 115, The executable code of the application 116, the firmware 117, the device authentication ns, the security key 119, the virtual engine 120, and the VPN code 122) may be stored in the security section 1-7C or the read-only section 107B. In addition, the executable code for the plurality of components can be forked and partially stored in the read-only section 丨〇 7B and the security section 丨〇 7c. Figure 2 illustrates a process flow diagram for protecting an operating system/application execution in one aspect of the present disclosure. The process begins in step S2, where the non-volatile memory device 105 is coupled to the host system 100 that detects the non-volatile memory device 1〇5. Most host systems today have one, plug and play, and options that can be detected as long as the device is plugged in. The firmware 117 or hardware (not shown) detects the type of operating system executing on the host system 100. After detecting the host operating system, in step S2〇2, the non-volatile 128115.doc -15-200837630 memory device 105 and the user using the device are identified. In one aspect, the servo identifies the non-volatile memory device 105 using device authentication 丨18. Standard or proprietary techniques can be used to identify the non-volatile memory device 105. For example, public key infrastructure (pκι) authentication (eg, 118) can be used to identify non-volatile memory devices 1〇5. The user may also have to authenticate himself or herself before allowing the user of the non-volatile memory device 105 to access the non-volatile memory device. This can be performed by using a unique user specific password generated by using the security key 119. The cryptographic engine 106 can be used to identify the non-volatile memory device 105 and the user. Step S2〇2 attempts to prevent unauthorized use of the non-volatile memory device 105. In step S204, the non-volatile memory device 1〇5 loads the code for a virtual machine (VOS1, V0S2, V0S3 or v〇Sn) into the ram 1〇3. In one aspect of the present disclosure, controller 1-6 can execute virtual engine code 120 to initialize a virtual environment. In another aspect, the virtual engine code 120 is detachable such that one code segment is executed by the host CPU (101, K 1A) and the other segment is executed by the non-volatile memory device 1 〇 5. This makes illegal copying or intrusion difficult. After initializing the virtual engine code 120, all other applications/codes (e.g., application 116) are executed in a virtual environment separate from the host operating system. In step S206, the host system 100 opens a virtual private network (VPN) connection (not shown) of one to one enterprise server or gateway (not shown). The nature of the network connection will depend on the connection, for example, the connection to a website 128115.doc • 16 - 200837630 or connected to the local area network. VPN code 121 can be used to open a VPN connection. At step S208, application 116 is executed in a suitable virtual operating system environment. The application 116 executes in a virtual environment independent of the host operating system controlled by the virtual engine 12A. Therefore, it is difficult to break into (invade) the application 116 to execute.

In one aspect of the present disclosure, the code for the application 116 is written so that the code can be executed in a virtual environment that is independent of a host system operating system. Therefore, different versions of the application 1 16 for different operating systems and platforms are not required. The reduced code development/maintenance assembly is stored in the read-only section of the non-volatile memory device 105 (eg, coffee). (or 107C)) 'It is therefore difficult to illegally reprint it. In a further aspect of the present disclosure, the user is provided with a security environment to conduct e-commerce transactions without changing the overall user experience, such as ▲ silver ordering. Once the non-volatile memory device 105 is connected and the environment is created, the user can navigate to a website with minimal piracy risk.
