Abstract: The disclosed technology provides for establishment of a secure tunnel with implicit device identification. The implicit device identification can be provided during establishment of a secure tunnel with a server by performing a mutual authentication with the server using a device-specific private key of the device. The device-specific private key may be provisioned during manufacturing of the device and stored by a secure hardware component of the device. Establishing the secure tunnel using implicit device identification can be helpful for operations in which a server is configured to only establish secure communications with one or more particular types of device, and can be performed without the use additional device identification communications.

Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for key space division and sub-key derivation for mixed media digital rights management content and secure digital asset distribution. A system practicing the exemplary method derives a set of family keys from a master key associated with an encrypted media asset using a one-way function, wherein each family key is uniquely associated with a respective client platform type, wherein the master key is received from a server account database, and identifies a client platform type for a client device and a corresponding family key from the set of family keys. The system encrypts an encrypted media asset with the corresponding family key to yield a platform-specific encrypted media asset, and transmits the platform-specific encrypted media asset to the client device. Thus, different client devices receive device-specific encrypted assets which can be all derived based on the same master key.

Abstract: In various embodiments, techniques for flexible resource authentication are provided. A principal attempts to login to a target resource using first credentials. The target resource does not recognize the first credentials and in response thereto forwards the first credentials to an identity service. The identity service authenticates the principal via the first credentials and supplies second credentials to the target resource. The target resource recognizes and authenticates the second credentials and grants access to the principal.

Abstract: Techniques for recognizing multiple patterns within a string of characters are presented. A dictionary is hierarchically organized, such that leaf nodes within the dictionary represents words defined in the dictionary. A string of characters are received. Each character within the string is traversed by attempting to match it with a character defined in the dictionary. As long as a match continues with the dictionary the characters within the string are traversed. Once a longest possible match to a word within the dictionary is found, the next character following the last matched character for the string is processed.
