    Abstract: A computer system that may include a trusted platform module (TPM) along with a processor hashes a user-supplied password for a predetermined time period that is selected to render infeasible a dictionary attack on the password. The results of the hash are used to render an AES key, which is used to encrypt an RSA key. The encrypted RSA key along with the total number of hash cycles that were used is stored and the RSA key is provided to the TPM as a security key. In the event that the RSA key in the TPM must be recovered, the encrypted stored version is decrypted with an AES key that is generated based on the user inputting the same password and hashing the password for the stored number of cycles.

    Abstract: A method of use protects a door hinge from splattered paint while allowing movement of the door, because the barrel portion is covered by the non-adhesive central portion of a masking tape. Use of a specialized roll of painter's masking tape includes the steps of having a longitudinal narrow region in the center without adhesive, in between two outer left and right regions which include adhesive. This non-adhesive center region is sized to match the circumference of the pin barrel exposed on the front of the hinge when opened flat. The tape is cut at predetermined lengths to form disposable masks for masking door hinges. The same tape is used for masking at least a portion of both the front butt plates as well as all of the back pin barrel side of the hinge. The front mask does not impede movement of the attached pivotably openable door.

    Abstract: A method for providing a secure single sign-on to a computer system is disclosed. Pre-boot passwords are initially stored in a secure storage area of a smart card. The operating system password, which has been encrypted to a blob, is stored in a non-secure area of the smart card. After the smart card has been inserted in a computer system, a user is prompted for a Personal Identification Number (PIN) of the smart card. In response to a correct smart card PIN entry, the blob stored in the non-secure storage area of the smart card is decrypted to provide the operating system password, and the operating system password along with the pre-boot passwords stored in the secure storage area of the smart card are then utilized to log on to the computer system.

    Abstract: Applications which function under a first operating system also function when it becomes necessary to call into action a second operating system due to provision having been made for configuration and other settings necessary to the execution of such applications (here generically called policy settings or policy source data) to be made available to the second operating system.

    Abstract translation: 在第一个操作系统下运行的应用程序也起作用，因为为了执行这些应用程序所必需的配置和其他设置（这里一般称为策略设置或策略源数据），必须为第二操作系统调用动作 ）可供第二个操作系统使用。
