Abstract:
The invention is a method of sending a message to an application embedded in a secured electronic token. The token is being intended to receive a first message from a distant machine. The token comprises a proxy agent and an admin agent which is able to manage the first message. The first message comprises a header and a body. The method comprises the steps of : - building a second message from the body of the first message when the first message is received by the admin agent, - forwarding the second message to the proxy agent if the header of the first message contains an element having a preset value - extracting an application identifier from the second message in the proxy agent, - forwarding the second message to the application if the extracted application identifier corresponds to the application.
Abstract:
The invention is a method for loading data into a portable secure token comprising a plurality of security domains. A first security domain comprises a first administration agent and a second security domain comprises a second administration agent. A remote application server comprises a first data to be provided to the second administration agent. A syndication server, which is distinct from the remote application server, contains a list which comprises a reference to the first data. The list is sent in response to a polling request that is sent by the first administration agent. This list is comprised in a polling response which is sent by the syndication server.
Abstract:
The invention is a method of managing an application embedded in a secured electronic token. The token is intended to receive a message from a server machine. The message has a header and a body. The token comprises an agent able to manage the message. The method comprises the steps of : a) registering the application in the agent by associating a reference of the application with a value of an element of the message header; b) when the message is received from the server machine, forwarding part of the message to the application if the message header contains an element having the value associated to the reference of the application.
Abstract:
The invention relates to a method for managing an memory LNVM erasable by block. The method comprises an index management of the memory blocks wherein the index indicates if a block is erased (Erased) or to be erased (TBE). A memory manager performs a block erasing when the memory is not in use and a block is to be erased and when the number of erased blocks is lower than a predetermined number.
Abstract:
The invention is method for managing access control in a system comprising a volatile memory and a non-volatile memory. The non-volatile memory comprises a first data of a first application and a second data of a second application. The method comprises the following steps: - creating in the volatile memory a tree structure comprising a first reference to said first data and a second reference to said second data, said system being configured to allow access to first and second data only by a request using one of said references stored in volatile memory, - upon activation of said first application, invalidating said second reference and updating the first reference with a value retrieved from the non-volatile memory.
