  • Patent number: 9264223
    Abstract: A security architecture in which a security module is integrated in a client machine, wherein the client machine includes a local host that is untrusted. The security module performs encryption and decryption algorithms, authentication, and public key processing. The security module also includes separate key caches for key encryption keys and application keys. A security module can also interface a cryptographic accelerator through an application key cache. The security module can authorize a public key and an associated key server. That public key can subsequently be used to authorize additional key servers. Any of the authorized key servers can use their public keys to authorize the public keys of additional key servers. Secure authenticated communications can then transpire between the client and any of these key servers. Such a connection is created by a secure handshake process that takes place between the client and the key server.

  • Patent number: 9224013
    Abstract: Systems and methods are provided that allow a secure processing system (SPS) to be implemented as a hard macro, thereby isolating the SPS from a peripheral processing system (PPS). The SPS and the PPS, combination, may form a secure element that can be used in conjunction with a host device and a connectivity device to allow the host device to engage in secure transactions, such as mobile payment over a near field communications (NFC) connection. As a result of the SPS being implemented as a hard macro isolated from the PPS, the SPS may be certified once, and re-used in other host devices without necessitating re-certification.

  • Publication number: 20150365404
    Abstract: Systems and methods for binding a smartcard and a smartcard reader are provided. A smartcard is provision to store a first set of credentials for use in traditional transactions such as at a brick and mortar retail store and a second set of credentials for use when performing a transaction using a smartcard reader associated with a user such as an on-line transaction. The user smartcard reader registers with a smartcard issuer server by cryptographically authenticating a secure processor associated with the smartcard reader. As a result of the registration, the secure processor obtains a set of private keys associated with the second set of credentials. When a request for a authorizing a transaction via the user's smartcard reader is received, the smartcard reader cryptographically authenticates itself to the smartcard using a private key associated with a credential to be used to authorize the transaction.
