摘要:
A hint containing user mapping information is provided in messages that may be exchanged during authentication handshakes. For example, a client may provide user mapping information to the server during authentication. The hint (e.g., in the form of a TLS extension mechanism) may be used to send the domain/user name information of a client to aid the server in mapping the user's certificate to an account. The extension mechanism provides integrity and authenticity of the mapping data sent by the client. The user provides a hint as to where to find the right account or domain controller (which points to, or otherwise maintains, the correct account). Based on the hint and other information in the certificate, the user is mapped to an account. The hint may be provided by the user when he logs in. Thus, a certificate is mapped to an identity to authenticate the user. A hint is sent along with the certificate information to perform the binding. Existing protocols may be extended to communicate the additional mapping information (the hint) to perform the binding. A vendor specific extension to Kerberos is defined to obtain the authorization data based on an X.509 certificate and the mapping user name hint.

Security protocols for mobile operator networks are described. In embodiments, mobile communication link is established between a mobile phone and a media content provider via a communication service provider with which the mobile phone is registered for mobile communications, and via at least one roaming node network with which the communication service provider has a roaming service agreement. The media content provider receives a security policy request from the mobile phone to establish a security policy for end-to-end security of the mobile communication link between the media content provider and the mobile phone for data communication security. The media content provider then communicates a security policy response to the mobile phone to establish the security policy for the end-to-end security of the mobile communication link that is adaptable to security restrictions of the roaming node network.

Various embodiments are disclosed that relate to the automated identification of one or more computer program functions for potentially placing on a remote computing device in a split-computational computing environment. For example, one disclosed embodiment provides, on a computing device, a method of determining a factorable portion of code to locate remotely from other portions of the code of a program to hinder unauthorized use and/or distribution of the program. The method includes, on a computing device, receiving an input of a representation of the code of the program, performing analysis on the representation of the code, the analysis comprising one or more of static analysis and dynamic analysis, and based upon the analysis of the code, outputting a list of one or more functions determined from the analysis to be candidates for locating remotely.

The method of delegating authentication, within a chain of entities, relies upon a recording of at least a portion of a TLS handshake between a gateway device and user, in which the user needs access to a desired server. The method then relies upon re-verification of cryptographic evidence in the recorded portion of the TLS handshake, which is forwarded either (1) to the server to which access is desired, in which case the server re-verifies the recorded portion to confirm authentication, or, (2) to a third party entity, in which case the third party entity confirms authentication and provides credentials to the gateway server which then uses the credentials to authenticate to the server as the user.

Various embodiments are disclosed that relate to decommissioning factored code of a program on a computing device. For example, one disclosed embodiment provides a method of operating a computing device. The method includes executing a program on the computing device, and while executing the program, identifying a remote location of a factored function via a code map, sending a call to the factored function and receiving a return response. The method further comprises, upon occurrence of a decommissioning event, receiving a copy of the factored function; and updating the code map with a location of the copy of the factored function.

Identifying a mobile operator account associated with a user to apply charges incurred by the user at a mobile marketplace service. The mobile operator provides an account identifier for the account to a billing token service associated with the mobile marketplace service. The billing token service creates a billing token including the account identifier, and provides the billing token to the user. When subsequently ordering from the mobile marketplace service, the user sends order requests with the billing token to the mobile marketplace service. The mobile marketplace service extracts the account identifier from the billing token and provides the order requests and the extracted account identifier to a mobile operator billing service. The mobile operator billing service applies a charge to the mobile operator account identified by the account identifier. Based on a charge status from the mobile operator billing service (e.g., a successful or unsuccessful charge), the mobile marketplace service allows or denies access by the user to an item identified in the order request.

Embodiments are disclosed that relate to hindering unauthorized use or distribution of a middleware program contained within an application. One example embodiment provides a method for hindering unauthorized use or distribution of a middleware program contained within an application. The method comprises acquiring factored middleware code, the factored middleware code having a missing function residing on a remote computing device, and building an application around the factored middleware code such that the application is configured to call to the remote computing device for execution of the missing function during use. The application may be configured to send a call to the remote computing device for execution of the missing function during use.

Mobile phone billing for content payment is described. In embodiments, a media content provider receives a billing identifier that is associated with a mobile phone. The billing identifier is received from a communication service provider that authenticates the mobile phone for communications, and a network communication link is established between the mobile phone and the media content provider via the communication service provider. The media content provider receives a request from the mobile phone to purchase and download a media asset. The media content provider determines the billing identifier that is associated with the mobile phone for the purchase of the media asset, and communicates a charge for the media asset to the communication service provider that then bills a user associated with the mobile phone. The user that is associated with the mobile phone is billed for the media asset in a mobile phone service bill.
