摘要:
A method for providing a warranty relating to a transaction between two parties, each party being a client of at least one respective institution which provides services to the respective party, the method including: transmitting a request for a warranty from one party to the transaction which is a client of the respective institution to a respective location associated with the respective institution, which request includes information identifying the other party to the transaction and information about the nature of the transaction; conducting an exchange of information between the respective location and a location associated with a institution of which the other party is a client; and transmitting a response to the request from the respective location to the one party.

In an infrastructure in which some of a plurality of entities provide cryptographically supported services, a method of registering a subscriber entity of a plurality of entities at a principal entity of a plurality of entities, the method comprising the subscriber entity requesting service from the principal entity by sending a request message to a registrar entity of the plurality of entities; the registrar entity verifying the subscriber entity and forwarding the request for service to the principal entity; the principal entity storing the forwarded request and transmitting an acknowledgement message to the registrar entity, the acknowledgement stating acceptance and authentication/authorization information that the subscriber entity requires for the requested service; and the registrar entity verifying the authenticity of the received acknowledgement message, and, if correct, forwarding the acknowledgement message to the subscriber entity.

A method, apparatus, and system for supply chain collaborative risk management of a cargo container. The invention includes a first entity for collecting data relevant to risks associated with the cargo container, and a second entity for receiving the data from the first entity, wherein the second entity combines the received data with risk relevant data and makes a determination of the risk of the cargo container.

A method for aiding transactions by providing warranties against various aspects of a transaction which may be hard to assure ahead of time or when high risk is involved in relying on them. The method employs an infrastructure of a computer and communication systems communication with various distributed organizations working together and providing warranties. Different parties may trust different organizations and user representatives of the infrastructure. A party in a transaction may ask for a warranty against another party. As a response, the infrastructure, through its organizations, calculates and provides a decision regarding the request. Relying on the warranty, the risk involved in conducting the electronic transaction is reduced. In the case where the transaction does not reach sound completion, the warranty can be claimed. The method also involves managing and administering the infrastructure, the entities in the transaction system and their outstanding warranties. Cryptographic sub-systems within the infrastructure components and the entities they serve are used to assure party/organization authentication and the validity of electronically signed messages within the transaction system. The warranty granting process, in turn, assures the transaction: its content, context, the parties and the parties' identification mechanisms, such as digital certificates.

Proactive robust threshold schemes are presented for general "homomorphic-type" public key systems, as well as optimized systems for the RSA function. Proactive security employs dynamic memory refreshing and enables us to tolerate a "mobile adversary" that dynamically corrupts the components of the systems (perhaps all of them) as long as the number of corruptions (faults) is bounded within a time period. The systems are optimal-resilience. Namely they withstand any corruption of minority of servers at any time-period by an active (malicious) adversary (i.e., any subset less than half. Also disclosed are general optimal-resilience public key systems which are "robust threshold" schemes (against stationary adversary), and are extended to "proactive" systems (against the mobile one). The added advantage of proactivization in practical situations is the fact that, in a long-lived threshold system, an adversary has a long time (e.g., years) to break into any t out of the l servers. In contrast, the adversary in a proactive systems has only a short period of time (e.g., a week) to break into any t servers. The model of mobile adversary seems to be crucial to such "long-lived" systems that are expected to span the secure network and electronic commerce infrastructure.

摘要:
A method of distributed cryptography for high consequence security systems which employs shared randomness between operating parties. Shared randomness is accomplished by sharing cryptographic keys stored in secure hardware tokens by potentially less secure software or general purpose computing units that perform distributed cryptography. The shared randomness is based on shared keys (at the tokens) and unique context. Shared random values are incorporated into the computation of partial results used in the distributed cryptographic calculation. The incorporation of shared randomness provides a hand-shake among the hardware tokens. When the operation is successful, a result is computed with assurance that the correct parties have taken part in forming the result. The hand-shake assures binding of operating parties and added system security.
