  • Publication number: 20260061326
    Abstract: Implementations relate to methods, systems, and computer-readable media to perform customized matchmaking. In some implementations, the method may include receiving a request from a user device of a requesting user to join a particular virtual experience, identifying virtual experience instances that are in progress, determining a first set of virtual experience instances eligible for the requesting user to join, obtaining one or more matchmaking rules that are associated with the particular virtual experience, determining a second set of virtual experience instances that satisfy the one or more matchmaking rules, determining a respective score for individual virtual experience instances in the second set of virtual experience instances based on one or more matchmaking scoring criteria, determining, based on the respective scores, a third set of virtual experience instances, and causing the user device to connect to the server that hosts a particular one of the third set of virtual experience instances.

  • Patent number: 7961882
    Abstract: Methods and apparatus are provided for using explicit initialization vectors in both encryption and decryption processing. In one example, a sender generates an initialization vector, identifies cryptographic keys, encrypts data using the initialization vectors and the cryptographic keys, and transmits the encrypted data in a packet along with the initialization vector. A receiver identifies cryptographic keys, extracts the initialization vector from the received packet, and decrypts the encrypted data using the cryptographic keys and the initialization vector extracted from the received packet.

  • Patent number: 7768108
    Abstract: A semiconductor die package. The semiconductor die package includes a leadframe structure, a first semiconductor die comprising a first surface attached to a first side of the leadframe structure, and a second semiconductor die attached to a second side of the leadframe structure. The second semiconductor die comprises an integrated circuit die. A housing material is formed over at least a portion of the leadframe structure, the first semiconductor die, and the second semiconductor die. An exterior surface of the molding material is substantially coplanar with the first surface of the semiconductor die.
    Type: Grant
