Abstract:
The invention relates to a method and a device for management of multimedia data. More particularly, the invention relates to a method and a device to allow an end-user to manage and keep with him his personal multimedia video and music Library. This method is based on a purchase of multimedia content step made using a first portable device of the end-user (10, 20, 30), and a multimedia content playing step on a distinct second device (70) used for displaying the multimedia content (40), this distinct second device (70) being a portable communication device.
Abstract:
The invention relates to a method for communicating with a personal token (10) over an IP network, in which method a request is made to the personal token and the personal token provides a response to this request, the method being characterized in that it comprises the step which consists in encapsulating (20) the said request to the personal token inside a message which is a response to a prior request emitted by the personal token for the purpose of such encapsulation.
Abstract:
The invention relates to a method for checking the integrity of a set of data packets received by a receiving communication device from a sending communication device, the data packets of the set being received in unpredictable order. The invention also relates to a communication device implementing a method according to the invention, in particular to a smart card.
Abstract:
Patching of software application. A software application is stored on a smart card as partitions and is loaded from the smart card into the memory of a host computer to which the smart card is connected. The software application is executed on the host computer; which using the instructions of the software application establishes a communications channel between the software application and a remote patch server containing a patch for at least one partition of the software application. Upon detecting that a patch is available for the at least one partition of the software application, downloading the at least one partition from the remote server into volatile memory allocated to the software application on the host computer via the first communications channel, and uploading the at least one partition from the volatile memory allocated to the software application to the smart card. Other systems and methods are disclosed.
Abstract:
The inventions relates to a personal security token (10) for a mobile telecommunicaction terminal (20) said personal security token (10) comprising a memory and a processor, said memory storing a content file (11), an access condition list (ACL) to such file (11) under a first security environment and an access condition list (ACL) to such file (11) under a second security environment, the two access condition lists being both stored in a given file (12) which is divided into records, characterized in that the access condition list (ACL) under the first security environment and the access condition list (ACL) under the second security environment are stored in the same record (13) of the said given file (12), and the token (10) stores and runs a program for identifying wether the token (10) is currently actuated under the first security environment or under the second security environment and reading only the access condition list which corresponds to the current security environment.
Abstract:
A system and method for detecting network-based attacks on an electronic device. The system and method operable to detect network-based attacks on the electronic device comprising receiving data packets on the electronic device, tracking disposition of the data packets by the electronic device by recording one or more paths through a finite state machine model of the processing of data packets by the electronic device, and raising an alert that the electronic device is under a network-based attack based on patterns of the one or more recorded paths
Abstract:
Role-based hierarchical access control system and method. A computer system having a data storage capacity and a central processing unit and at least one resource has an access control data structure defining role-based access control lists for the resource, wherein the access control list defines based on the role of a user the types of access that the user may have to the at least one resource. A hierarchy of roles having at least a first role and a second role wherein the second role inherits the permissions granted to the first role for the at least one resource. Access to the resource is determined by comparing roles defined to have access privileges to the resource and the permissions granted to such roles to the role of an entity seeking access to the resource.
Abstract:
The invention relates to a personal token (PT) for a hosting telecommunication terminal (T) such personal token (PT) storing a secret master key and comprising a microprocessor and a software equipment for interpreting at least one incoming command so as to generate first derived key material on the basis of the stored secret master key and on the basis of the content of said incoming at least one command, said software equipment controlling interpretation of said command so as to determine whether said command indicates that the first derived key material should be delivered to the hosting terminal (T) or not, characterized in that the software equipment performs a checking task as to whether the command comprises a content which complies with a predetermined content format and refuses to proceed to delivery of the first derived key material in case said content does not comply with said content format.
Abstract:
A mobile device and UICC communication using standard Internet protocols. Such communication allows users access to their UICC information using standard web browsers and allows use of the UICCs to communicate with remote servers and thereby provide secure services for Internet transactions. The mobile device has a communications module to selectively communicate with the UICC processor or with at least one node on a network, the mobile device communications module has an Internet protocol module operable to receive messages issued from a first Internet application as Internet protocol packets, and to transmit the packets to target IP addresses; and operable to receive Internet protocol packets, to process the packets, and to send the messages contained in the packets to the first Internet application.
Abstract:
The system comprises a terminal (10, 12), an independent portable device (20) including a data processing means, and a wireless coupling means (RF COMMUNICATION) for exchanging individual-identification data between said terminal and said portable device. A body-medium communication means (OSC COMMUNICATION) including a transmitter in the terminal and a receiver in the portable device is provided to transmit from the terminal to the portable device a connection code (CONNECTION CODE) at the onset of a transaction upon physical contact established by the individual between the terminal and the portable device. A control means in the portable device checks said connection code received and conditionally issues to the terminal through said wireless coupling means (RF COMMUNICATION) a signal for enabling further execution of said transaction in response to said connection code complying with predetermined criteria.
