Patent number: 8495381Abstract: This invention provides a simple and secure PIN unblock mechanism for use with a security token. A set of one or more passphrases are stored on a remote server during personalization. Likewise, the answers to the passphrases are hashed and stored inside the security token for future comparison. A local client program provides the user input and display dialogs and ensures a secure communications channel is provided before passphrases are retrieved from the remote server. Retrieval of passphrases and an administrative unblock secret from the remote server are accomplished using a unique identifier associated with the security token, typically the token's serial number. A PIN unblock applet provides the administrative mechanism to unblock the security token upon receipt of an administrative unblock shared secret. The remote server releases the administrative unblock shared secret only after a non-forgeable confirmatory message is received from the security token that the user has been properly authenticated.Type: GrantFiled: August 6, 2007Date of Patent: July 23, 2013Assignee: ActivcardInventor: Mark Herbert Priebatsch

Publication number: 20130145442Abstract: This invention provides a privilege delegation mechanism, which allows a privilege and associated control attributes to be delegated from a security token to another security token or an intelligent device such as a computer system. The privilege may be in the form of an attribute certificate, a key component of a cryptographic key, a complete cryptographic key, digital certificate, digital right, license or loyalty credits. The purpose of the delegation is to allow another security token or computer system to act as a surrogate for the security token or to access a resource which requires components from both units before access is permitted. Attributes associated with the delegated privilege control the scope and use of the privilege. The delegation may allow the surrogate to perform authentications, access data or resources included on another security token or computer system. Authentications are performed prior to transferring of the delegable privileges.Type: ApplicationFiled: September 25, 2012Publication date: June 6, 2013Applicant: ACTIVCARDInventor: ACTIVCARD

Patent number: 5937068Abstract: The system includes a first card-like unit adapted to communicate with a second unit giving only conditionally access to a function. Both units are capable of running software for generating a password by means of encryption of a plurality of dynamic variables produced separately but in concert (so as to have a predetermined relationship, such as identity, with one another) in the units. The encryption is carried out in each unit by a public algorithm using a dynamically varying encryption key. Each time an access request is issued by a card user, the key is modified as a function of the number of access requests previously formulated by the card user. Access to the function is granted when the passwords generated in the units have a predetermined relationship (such as identity) with each other.Type: GrantFiled: October 2, 1997Date of Patent: August 10, 1999Assignee: ActivcardInventor: Yves Audebert

Patent number: 5887065Abstract: The system includes a first unit adapted to communicate with a second unit. The second unit grants conditional access to a function or service in accordance with an authentication operation. Both units are capable of running software for generating passwords by means of encryption of several dynamic variables as for example a time dependent variable and/or a variable representing the number of formulated authentication requests. The encryption may be performed using a dynamic key. In order to synchronize the values of the variables generated in concert but independently in the units, only some of the least significant digits of the variables are transferred from the card-like unit to the other unit, with the transfer being performed by adding the digits to the password.Type: GrantFiled: October 2, 1997Date of Patent: March 23, 1999Assignee: ActivcardInventor: Yves Audebert
