20090165083 | METHOD AND APPARATUS FOR MANAGING POLICIES FOR TIME-BASED LICENSES ON MOBILE DEVICES - Methods and devices provide for creating, managing, modifying, and/or enforcing flexible digital rights management license policies for protecting games, media, data, or other software with a time-based license. Embodiments are especially directed toward situations in which a source of time is unavailable, untrustworthy, or unreliable. Licenses are defined by a small number of parameters. Parameter values may be defined by and included with protected content or applications. The parameter values may be chosen to define and enforce a desired level of compromise between usability and security characteristics. | 06-25-2009 |
20100173608 | SAFE APPLICATION DISTRIBUTION AND EXECUTION IN A WIRELESS ENVIRONMENT - The present invention provides safe and secure application distribution and execution by providing systems and methods that test an application to ensure that it satisfies predetermined criteria associated with the environment in which it will execute. Furthermore, by using rules and permission lists, application removal, and a modification detection technique, such as digital signatures, the present invention provides mechanisms to safely distribute and execute tested, or untested, applications by determining whether the application has been modified, determining if it has permission to execute in a given wireless device environment, and removing the application should it be desirable to do so. | 07-08-2010 |
20100325708 | SYSTEM AND METHOD FOR PROVIDING A MULTI-CREDENTIAL AUTHENTICATION PROTOCOL - A system and method for providing secure communications between remote computing devices and servers. A network device sends characteristics of a client computing device over the network. A network device receives characteristics of a client computing device over the network. A plurality of credentials are generated where at least one of the plurality of credentials based on both the received characteristics of the client computing device and a unique client key, and at least one of the plurality of credentials based on both the received characteristics of the client computing device and a generic key. A network device sends the plurality of credentials over the network. A network device receives the plurality of credentials via the network. | 12-23-2010 |
20110107107 | Multisigning - A Protocol For Robust Multiple Party Digital Signatures - 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. | 05-05-2011 |
20120030742 | METHODS AND APPARATUS FOR PROVIDING APPLICATION CREDENTIALS - Methods and apparatus for providing an application credential for an application running on a device. In one embodiment, a method provides an application credential to an application running on a device, wherein the application credential is used by the application to authenticate to a data server. The method comprises receiving a request to generate the application credential, wherein the request includes an application identifier. The method also comprises generating the application credential using the application identifier and a master credential associated with the device. | 02-02-2012 |
