  • Patent number: 11683170
    Abstract: A secure digital communications method is provided in which a Certificate Authority generates an improved RSA key pair having a modulus, a public key exponent, a public key, and a private key. The public key exponent can contain descriptive attributes and a digital signature. The digital signature can be responsive to the descriptive attributes and the modulus. A secure session can be established between a first system and a second system, within a secure digital communication protocol. The second system can verify the digital signature to authenticate the public key.

  • Patent number: 10498540
    Abstract: A method and system are provided for improved distributing of a complete software image to all electronic devices of a certain type or model while using encryption to limit its use to specific ones of those devices. In the method, the entire software image is encrypted with a global key and the encrypted software image is distributed to all devices which have the capability of running that software. The global software decryption key for decrypting the software image is uniquely encrypted for every device that is authorized to use the software and the encrypted global software key is distributed to those devices from a field or factory provisioning server across a point-to-point connection.

  • Patent number: 9485230
    Abstract: A method provides end-to-end security for transport of a profile to a target device (e.g., a mobile computing device) over at least one communications network that includes a plurality of nodes. In accordance with the method, the profile is encrypted for transport between the target device and an initial node of the network through which the profile is transported. The encryption is an end-to-end inner layer encryption performed prior to hop-to-hop encryption. The encrypting uses a public key of a public, private key pair. The private key is derivable from a seed securely provisioned in the target device using a public key algorithm. The encrypted profile is transmitted over the communications network to the target device.

  • Patent number: 9197910
    Abstract: A system for securely authenticating software Application Program Interfaces (APIs) includes a handshake protocol that enables promulgation of licensing rights controlling Intellectual Property (IP) to multiple Actors. The handshake is a Challenge-Response protocol that includes a Challenge issued by one Actor who controls IP rights to verify a second Actor has Licensed IP rights when the second Actor Response includes use of a function IPF1. The function e.g. IPF1 is provided through the IP licensing agreement. Other Actors who wish to use software that the first Actor provides will be encouraged to acquire rights to the IP License to obtain the function IPF1 for access. Subsequent Actors who have IP rights controlled by another function IPF2 can be pulled into the same IP Licensing system, or another IP License that becomes part of the same ecosystem with the system controlled using function IPF1.
