US 2002/0178360 A1 · System and method for communicating a secure unidirectional response message

Abstract

System, method, signal, operating model, and computer program for electronic messaging. Systems and method for providing security for communication of electronic messages, interactive sessions, software downloads, software upgrades, and other content from a source to a receiving device as well as signals used for such communications. Systems, methods, signals, device architectures, data formats, and computer program structures for providing authentication, integrity, confidentiality, non-repudiation, replay protection, and other security properties while minimizing the network bandwidth, computational resources, and manual user interactions required to install, enable, deploy and utilize these security properties. System, device, method, computer program, and computer program product for searching and selecting data and control elements in message procedural/data sets for automatic and complete portrayal of message to maintain message intent. System, device, method, computer program, and computer program product for adapting content for sensory and physically challenged persons using embedded semantic elements in a procedurally based message file.

Dependent claims

A computer program product for use in conjunction with a computer system having a server and a client, the computer program product comprising a computer readable storage medium and a computer program mechanism embedded therein, the computer program mechanism, comprising:

a program module that directs the computer system and/or components thereof including at least one or the client or server, to function in a specified manner to provide message communications, the message communications occurring in a computer system hardware architecture neutral and operating system neutral and network transport protocol neutral manner for secure unidirectional response message, the program module including instructions for:
A. extracting, by a Client who is sending a secure response message to the Entity in order to respond to a message from the Entity, the Entity's public key and matching destination address of the Entity from a trusted storage means;
B. extracting, by the Client, the Client's public and private key and certificate chain from a trusted source or storage means;
C. using, the extracted Client's public and private key and certificate chain information along with the previously extracted Entity's destination address to create a secure unidirectional message to the Entity using the a secure unidirectional message protocol, a data portion of the Client's message containing a Resource Tag that was included in the message received from the Entity to which this message is a response;
and
D. verifying, by the Entity, the Client's certificate chain.
