Patent number: 9117324Abstract: 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.Type: GrantFiled: February 27, 2012Date of Patent: August 25, 2015Assignee: Broadcom CorporationInventor: Mark Buer

Publication number: 20150058620Abstract: An authorized user may be provided access to a service only when a wireless token assigned to the user is in the proximity of a computing device. A user's credential may be stored on an RFID token and an RFID reader may be implemented within a security boundary on the computing device. Thus, the credential may be passed to the security boundary without passing through the computing device via software messages or applications. The security boundary may be provided, in part, by incorporating the RFID reader onto the same chip as a cryptographic processing component. Once the information is received by the RFID reader it may be encrypted within the chip. As a result, the information may never be presented in the clear outside of the chip. The cryptographic processing component may cryptographically encrypt/sign the credential received from the token.Type: ApplicationFiled: July 30, 2014Publication date: February 26, 2015Applicant: BROADCOM CORPORATIONInventors: Mark BUER, Ed FRANK, Nambi SESHADRI

Patent number: 8958821Abstract: A multi-radio mobile device comprises a plurality of different radios. When a location update occurs, the multi-radio mobile device, at a specific location, acquires location-based radio information from a remote location server. The multi-radio mobile device selects a radio for use in the specific location based on the acquired location-based radio information comprising available radios in the specific location and radio weights. The radio is selected from the available radios based on the radio weights in the specific location. Transmissions of a desired service are received in the specific location utilizing the selected radio. Location-based radio measurements reports to the remote location server are generated utilizing signal strength measurements for the received signals. Radio quality information of the available radios is calculated by the location server utilizing location-based radio measurement reports from associated users.Type: GrantFiled: August 26, 2013Date of Patent: February 17, 2015Assignee: Broadcom CorporationInventors: Charles Abraham, Mark Buer, David Garrett, Jeyhan Karaoguz, David Albert Lundgren, David Murray
