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:

Computer-based method and system for aiding transactions

A method for providing a warranty relating to a transaction between two parties, each party having a data communications device, in a system which includes an infrastructure composed of a plurality of locations each associated with a respective institution which provides services to clients, each location having a computer system, a database coupled to the computer system and storing information about each client of the institution and a data communications device coupled to the computer system for communication with the data communications device of any one party, each party being a client of at least one of the institutions, the method containing the steps of:

Methods, systems and devices for cryptographic control and maintenance of organizational structure and functions are provided. A method for control and maintenance of an operational organizational structure, the method includes associating entities with cryptographic capabilities; organizing entities within the organizational structure as roles; and maintaining roles within the organizational structure. The system may involve at least a Public Key Infrastructure operation. Elements in said organizational structure may be assigned to roles and/or groups within said organizational structure.

Cryptographic control and maintenance of organizational structure and functions

A method for facilitating provision of a warranty relating to a transaction between two parties in a system which includes an infrastructure composed of a plurality of locations each associated with a respective institution which provides services to clients, the method containing the steps of 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.

Methods for operating infrastructure and applications for cryptographically-supported services

An electronic transaction system includes an authority issuing electronic signals representing subscriber assurance of an attribute of a subscriber to the system; and a reliance server obtaining electronic signals representing information regarding the subscriber assurance issued by the issuing authority, the reliance server issuing electronic signals representing a signed warranty offer to a relying party, the signed warranty offer being based at least on the subscriber attribute assurance, wherein the reliance server only provides the signed warranty offer if the relying party is authorized to make a request for said warranty.

Reliance manager for electronic transaction system

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.
