摘要： Disclosed is a method for generating a privilege-based key using a computer. In the method, a privilege is received from an application, and verified as being associated with the application. The computer cryptographically generates a second key using a first key and the privilege. The second key is provided to the application.

摘要： Embodiments describe a system and/or method for multiple party digital signatures. According to a first aspect a method comprises establishing a first validity range for a first key, establishing a first validity range for at least a second key, and determining if the validity range of the first key overlaps the first validity range of the at least a second key. A certificate is signed with the first validity range of the first key and the first validity range of the at least a second key if the validity ranges overlap. According to another embodiment, signage of the certificate is refused if the first validity range of the first key does not overlap with the first validity range of the at least a second key.
摘要翻译： 实施例描述了用于多方数字签名的系统和/或方法。 根据第一方面，一种方法包括建立第一密钥的第一有效范围，为至少第二密钥建立第一有效范围，以及确定第一密钥的有效范围是否与至少一个密钥的第一有效范围重叠 第二个关键 如果有效范围重叠，则证书具有第一密钥的第一有效范围和至少第二密钥的第一有效范围。 根据另一实施例，如果第一密钥的第一有效范围不与至少第二密钥的第一有效范围重叠，则拒绝证书的标识。

摘要： Methods, apparatus, and systems are described for providing an accessor device an access credential to interact with a device resource on an accessee device. An authorization entity having a trust relationship with the accessee device, or a linked subordinate authorization entity, generates the access credential. The access credential includes a modification detection indicator, at least one access privilege, and an accessor public key. The at least one access privilege corresponds to at least one device resource on the accessee device. The authorization entity forwards the access credential to the accessor device, which presents the access credential to the accessee device for authentication. Once authenticated, the accessee device grants access to one or more device resources, and controls requests to insure they are within the scope of the at least one access privilege.

摘要： A method of providing access to content within a user device is disclosed and may include determining a location of the content, determining whether the content is within an allowed region, and selectively prompting a user to purchase a license to access the content. In a particular aspect, the user may be prompted to purchase the license to the access the content when the content is not within an allowed region. If the license is purchased, the user may be allowed to access the content. The license may be an unlimited license, a limited license, or a transfer license.
