A method of detecting unauthorized activity in an electronic message transfer system comprising a plurality of devices, each device being configured to generate and receive cryptographically secured transfer messages for exchanging content with other devices in the system. In each device, audit information is accumulated in a memory of the device. The device periodically forwards at least part of its accumulated audit information to a secure server.

Electronic transaction risk management

An electronic content storage and exchange system includes an interface configured to send and receive messages; a database and a controller. The database includes a plurality of records, each record representing a respective virtual storage media and including at least: a respective unique identifier assigned to the virtual storage media; a respective Private key and certificate assigned to the virtual storage media; a current content value, and a log of content transfers. The controller executes transfer-in and transfer-out processes in respect of each of the virtual storage media. The transfer-in process includes steps of: receiving a content transfer message including at least a message content to be transferred and the respective identifier assigned to a recipient virtual storage media; accessing the record representing the recipient virtual storage media; and storing the message content in the current content of the recipient virtual storage media. The transfer-out process includes steps of: receiving a content transfer request message including at least at least a message content to be transferred and the respective identifier assigned to a sending virtual storage media; accessing the record representing the sending virtual storage media; removing the message content from the current content; generating a content transfer message including the message content; and returning the content transfer message.

Trusted message storage and transfer protocol and system

A secure asset storage and transfer system. A first display displays a first bar code encoding a request message including an asset value amount to be transferred. A first camera-equipped device is configured for: reading the first bar code, decoding the first bar code to recover the request message; generating a value transfer message for transferring asset value amount to be transferred from a storage medium associated with the camera-equipped device; encoding the value transfer message to generate a corresponding second bar code; and displaying the second bar code on a second display. A second camera-equipped device is configured for reading the second bar code, and decoding the second bar code to recover the value transfer message.

Using bar-codes in an asset storage and transfer system

An electronic content exchange system includes a communications medium and at least two storage media. Each storage media includes an interface configured to send and receive messages, a memory storing a current content, a respective unique identifier, and a log of content transfers; and a controller. The controller receives a content transfer message including at least a message content to be transferred, and executes a Transfer-in process to increase the current content by the message content to be transferred and record information of the transfer in the log. The controller receives, via the interface, a content transfer request message including at least a message content to be transferred, and executes a Transfer-out process to generate and send a content transfer message including the message content to be transferred, decreasing the current content by the message content to be transferred; and recording information of the transfer in the log.

Message storage and transfer system

A security domain control method includes defining a sequential series of security domains; designating one of the security domains as a current domain; generating a plurality of security tokens under the current security domain, each security token being configured to enable a party to exchange cryptographically secured messages with another party that is holding any one of: a token generated under the current security domain; a token generated under at least one next security domain in the series; and a token generated under at least one previous security domain in the series; and subsequently designating a next one of the security domains in the series as a current domain.

Controlled security domains

Methods, apparati and computer-readable media for securely loading a software module over a communications network from a software provider (SP)() onto a tamper resistant module (TRM)().

Tamper resistant module having separate control of issuance and content delivery

Methods, apparati, and computer-readable media for securely transporting a software application onto a tamper resistant module (TRM) () by using an individualized TRM key set. A method embodiment of the present invention comprises: storing a key pair unique to the TRM () in a memory located on the TRM (), where the key pair comprises a TRM public key () and a TRM private key (); retrieving the TRM public key from the TRM; encrypting a portion of the software application using the TRM public key (); transmitting the encrypted software application to the TRM (); and recovering and decrypting the encrypted software application using the TRM private key ().

Key transformation unit for a tamper resistant module

Methods and apparati for securely loading one or more computer software applications onto a tamper resistant module (TRM) () and for securely deleting one or more applications from the TRM. An embodiment of the invention comprises a method for determining, based at least upon an encrypted personalization data block, whether a TRM () is part of a qualified set of TRM's to accept loading of an application. Thereafter, the method provides for loading the application onto the TRM () only after the first step determines that the TRM () is qualified to accept the loading of the application. Another embodiment comprises a method for determining, based at least upon an encrypted personalization data block, whether a TRM () is part of a qualified set of TRM's to accept deleting of an application. Thereafter, the method provides for deleting the application from the TRM () only when the first step determines that the TRM () is qualified to accept the deleting of the application.

Tamper resistant module certification authority

Methods and systems for flexibly loading an application, e.g., a software application, and associated data from an application provider () onto a tamper resistant module (TRM) () having an I/O buffer () and a memory (). A method embodiment of the invention comprises determining () the size of the TRM's I/O buffer (), segmenting () the application to be loaded and its associated data into a plurality of segments, with each segment adapted to be stored in the I/O buffer () and the size of each segment being a function of the determined size of the I/O buffer (), separately transmitting () each segment to the tamper resistant module (), and storing () each separately transmitted segment in a selected one of one or more available spaces of the TRM's memory (), said spaces selected depending upon the size of each segment and upon which of said available spaces has the smallest available area in the TRM's memory () in which the segment can be stored.
