    摘要: A method and apparatus for booting a computer. The method comprises the steps of emulating a floppy disk drive communicatively coupled to a computer in a token via a USB-compatible interface, and booting the computer using the token. The apparatus comprises means for performing these functions, including a token with a processor having one or more memories storing processor instructions and data for performing the method steps. The memory may also securely store sensitive data.

    摘要: A method is provided for protecting distributed software which relies on a unique factor such as an accessible serial number or the generation of a profile or fingerprint of the computer of the user which is entered individually and/or with a random factor to generate a unique first key which will differ for different computers. The first key is sent to a processing center which then generates a second key. The user applies the second key which compares the unique and/or random factors. If the comparison matches, the first and second keys are used in an algorithm in the software to generate a decrypting key permitting the customer to purchase the selected program(s).

    摘要: A hypervisor runs on a host computer system and defines at least one virtual machine. An address space of the virtual machine resides on physical memory of the host computer system under control of the hypervisor. A guest operating system runs in the virtual machine. At least one of a host operating system and the hypervisor sets parts of the address space of the host computer system corresponding to parts of the address space of the virtual machine to a locked state in which those parts can be read but not written to.

    摘要: In an embodiment of a method of and system for detecting rollback of usage data, the usage data is recording in a database. A sequence value in the database is repeatedly advanced. A copy of the sequence value is repeatedly saved to protected storage. The copy of the sequence value in the protected storage is compared with the sequence value in the database, and it is determined whether the result of the comparison is consistent with normal operation of the database since the previous save to protected storage.

    摘要: A method and apparatus for securing a token from unauthorized use is disclosed. The method comprises the steps of receiving a first message transmitted from a host processing device and addressed to a PIN entry device according to a universal serial bus (USB) protocol; accepting a PIN entered into the PIN entry device; and transmitting a second message comprising at least a portion of the first message and the PIN from the PIN entry device to the token along a secure communication path. In another embodiment, the present invention describes an apparatus for securing a token from unauthorized use, comprising a PIN entry device, communicably coupleable to a host processing device transmitting a first message addressed to the PIN entry device, and communicatively coupleable to the token according to a universal serial bus USB protocol, the PIN entry device comprising a user input device, for accepting a user-input PIN; and a processor, communicatively coupled to the user input device, the processor for receiving the first message and combining the first message with the user-input PIN, and for producing a second message having at least a portion of the first message and the user-input PIN.
