1. A computer-implemented method for securely delivering a document from a sender to a recipient, the method comprising an operations center (OC) performing the steps of:
- associating the sender with a sender public key from a sender public-private key pair;
using the sender public key, in conjunction with the sender using the sender private key, to authenticate the sender;
establishing a first secure connection between the sender and the OC;

Abstract
An Operations Center (OC) (200) acts as a central key manager and intermediary in securely, reliably and non-repudiably delivering a document (3) from a sender (100) to a recipient (300). The OC (200) acts as a key manager to facilitate the process of strong authentication of the sender (100) and the recipient (300), encryption of the delivery (510), and setup of reliable connections (2A, 2B, 2C). In a preferred embodiment, the reliable connections (2A, 2B, 2C) are virtual private network connections.

24. A system for securely delivering a document from a sender to a recipient, the system comprising an operations center (OC) comprising:
-
a key manager module for associating the sender with a sender public key from a sender public-private key pair and for associating the recipient with a recipient public key from a recipient public-private key pair;
a directory interface, coupled to the key manager module and to a public key database and an escrow key manager, for searching and returning one key from a group of keys comprising a recipient public key and an escrow encryption key, upon request from the sender for an encryption key;
an authentication module, coupled to the key manager module, for using the sender public key, in conjunction with the sender using the sender private key, to authenticate the sender;
a secure connection module, coupled to the authentication module, for establishing a first secure connection between the sender and the OC; and
a messaging module, coupled to the secure connection module, for receiving a request from the sender for an encryption key to secure a delivery, the delivery comprising at least the document, and for transmitting to the sender one from a group comprising the recipient public key and the escrow encryption key. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
