Patent number: 10608828Abstract: Providing revocation status of at least one associated credential includes providing a primary credential that is at least initially independent of the associated credential, binding the at least one associated credential to the primary credential, and deeming the at least one associated credential to be revoked if the primary credential is revoked. Providing revocation status of at least one associated credential may also include deeming the at least one associated credential to be not revoked if the primary credential is not revoked. Binding may be independent of the contents of the credentials and may be independent of whether any of the credentials authenticate any other ones of the credentials. The at least one associated credential may be provided on an integrated circuit card (ICC). The ICC may be part of a mobile phone or a smart card.Type: GrantFiled: November 13, 2017Date of Patent: March 31, 2020Assignee: ASSA ABLOY ABInventors: Eric F. Le Saint, Robert F. Dulude

Patent number: 10554393Abstract: An anonymous secure messaging method and system for securely exchanging information between a host computer system and a functionally connected cryptographic module. The invention comprises a Host Security Manager application in processing communications with a security executive program installed inside the cryptographic module. An SSL-like communications pathway is established between the host computer system and the cryptographic module. The initial session keys are generated by the host and securely exchanged using a PKI key pair associated with the cryptographic module. The secure communications pathway allows presentation of critical security parameter (CSP) without clear text disclosure of the CSP and further allows use of the generated session keys as temporary substitutes of the CSP for the session in which the session keys were created.Type: GrantFiled: November 7, 2013Date of Patent: February 4, 2020Assignee: ASSA ABLOY ABInventors: Eric F. Le Saint, Wu Wen

Patent number: 10467832Abstract: A portable authentication system includes a security module, that may be a smart card, SIM (Subscriber Identity Module), USB controller with a secure chip, or similar module capable of storing one or more credentials, and an interface module such as a digital badge holder that is able to communicate with the security module, for instance by providing a smart card communication interface. The portable authentication system may be either a single integrated system or a dual system where the security module can be removed or disconnected from the interface system.Type: GrantFiled: December 27, 2018Date of Patent: November 5, 2019Assignee: ASSA ABLOY ABInventors: Yves Louis Gabriel Audebert, Eric F. Le Saint, Jason Hart, Dominique Louis Joseph Fedronic

Patent number: 10454675Abstract: A method, system and computer program product for ensuring PKI key pairs are operatively installed within a secure domain of a security token prior to generating a digital certificate. The public key component of the PKI key pair is incorporated into a digital certificate which is returned to the security token for storage. The arrangement included herein incorporates the use of a critical security parameter to ensure a chain of trust with an issuing entity such as a registration authority. Furthermore, the arrangement does not require security officer or system administrator oversight during digital certificate generation as the critical security parameter provides a sufficient level of trust to ensure that digital certificate generation is being performed in conjunction with a designated security token rather than a rogue application. Lastly, separate inventive embodiments allow alternate communications and verification arrangements to be implemented.Type: GrantFiled: February 6, 2017Date of Patent: October 22, 2019Assignee: ASSA ABLOY ABInventor: Eric F. Le Saint

Patent number: 10178078Abstract: A secure and transparent digital credential sharing arrangement which utilizes one or more cryptographic levels of indirection to obfuscate a sharing entity's credentials from those entities authorized to share the credentials. A security policy table is provided which allows the sharing entity to selectively authorize or revoke digital credential sharing among a plurality of entities. Various embodiments of the invention provide for secure storage and retrieval of digital credentials from security tokens such as smart cards. The secure sharing arrangement may be implemented in hierarchical or non-hierarchical embodiments as desired.Type: GrantFiled: December 27, 2016Date of Patent: January 8, 2019Assignee: Assa Abloy ABInventors: John Jules Alexander Boyer, Eric F.

Patent number: 10127377Abstract: Managing validity status of at least one associated credential includes providing a credential manager that selectively validates associated credentials for at least one device, the device invalidating a corresponding associated credential, and the device requesting that the credential manager validate the corresponding associated credential after invalidating the associated credential. The associated credential may be invalidated based on an external event, such as a user invalidating the associated credential from a UI of the device, a user improperly entering a pin value, a user indicating that a corresponding device is lost, the device entering sleep mode, the device locking a user interface thereof, the device shutting down, and a particular time of day. The at least one associated credential may be provided on an integrated circuit card (ICC) that may be part of a mobile phone and/or a smart card.Type: GrantFiled: December 28, 2017Date of Patent: November 13, 2018Assignee: Assa Abloy ABInventor: Eric F.

Patent number: 10042990Abstract: Atomically modifying a personal security device includes presenting the personal security device to a reader/writer coupled to an access module, the access module determining if the personal security device includes a factory security mechanism, and, if the personal security device includes a factory security mechanism, using the reader/writer and the access module to replace the factory security mechanism with another security mechanism. The access module may authenticate the personal security device in connection with replacing the factory security mechanism. Authenticating the personal security device may grant access to a user through a door controlled by the access module. Replacing the factory security mechanism may include replacing an application on the personal security device. An ISO/IEC 7816-13 application management request command may be used to replace the application.Type: GrantFiled: March 26, 2013Date of Patent: August 7, 2018Assignee: Assa Abloy ABInventors: Kapil Sachdeva, Philip Hoyer, Eric F.

Publication number: 20170195368Abstract: A security framework for a host computer system which allows a host to control access to a compliant security token by ensuring enforcement of established security policies administered by a middleware application. Processing between the host computer system and the security token is performed using one or more modular security application agents. The modular security application agents are counterpart applications to security applications installed in the security token and may be retrieved and installed upon to ensure compatibility between counterpart token and host security applications. The security policies are a composite of host security policies and token security policies which are logically combined by the middleware application at the beginning of a session.Type: ApplicationFiled: January 10, 2017Publication date: July 6, 2017Inventors: Eric F.
