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.

Abstract: A system, method and computer readable medium for securely transmitting an information package (10) to an addressee (190) via a network (108), wherein an addressee (190) is not required to have a private-public key pair before the package (10) is sent. A sending system (102) encrypts the package (10) with a package encryption key (600) and then encrypts a package decryption key (601) with an escrow encryption key (380) obtained from an escrow key manager (116). The encrypted package (10) and encrypted package decryption key (601) are held in escrow by a server system (104), until the addressee (190) is issued a new public and private key pair (390, 391). The server system (104) decrypts the package decryption key (601), re-encrypts it with the addressee's new public key (390), and forwards the encrypted package (10) and re-encrypted package decryption key (601) to the addressee's receiving system (106). The receiving system (106) receives the delivery and decrypts the information package (10).

Abstract: Systems, methods, and computer-readable medium for securely transmitting data (400) between at least two access systems (300, 320) via a switch system (310). Through the use encryption keys and the switch system (310) acting a central switch, any two access systems are able to securely transmit data (400) between them. The present invention can be implemented by means of an application proxy (1000), a secure connection enabled application, or application program interfaces.

Abstract: Applications are integrated with application-specific certification authorities (CAs) for issuing application-specific certificates. For each certificate issued to a subscriber by a master CA, the application-specific CAs issue corresponding application-specific certificates to the subscriber. For each certificate revoked master CA, the application-specific CAs revoke the corresponding application-specific certificates of the subscriber.
