Abstract: The present invention provides a system and method for providing certified voice and/or multimedia mail messages in a broadband signed communication system which uses packetized digital information. Cryptography is used to authenticate a message that has been compiled from streaming voice or multimedia packets. A certificate of the originator's identity and electronic signature authenticates the message. A broadband communication system user may be provisioned for certified voice and/or multimedia mail by registering with a certified mail service provider and thereby receiving certification. The called system user's CPE electronically signs the bits in received communication packets and returns the message with an electronic signature of the called system user to the calling party, along with the system user's certificate obtained from the service provider/certifying authority during registration. The electronic signature is a cryptographic key of the called party.

Abstract: A system and method are provided for use in establishing secure end-to-end communication links over a VPN gateway via a network interface unit. Illustrative embodiments include establishing and providing secure communication relationships between users (customers) and companies for e-commerce and other business purposes. Each company's data and linkage to users remaining private and secure from the other participating companies as well as from the general public over the Internet. Login by user with network interface units, addressing, authentication, and other configuration operations achieved using a web page-based GUI are applied in establishing tunnels from LAN clients to desired VPN destinations. Required authentication exchanges and required encryption key exchanges facilitate the secure communications. Financial arrangements regarding the provisioning and use of network interface units are also disclosed.

Abstract: A mechanism is provided to build and maintain a searchable database of communication content and related indicia information of all voice and multimedia (audio and video) communications in which a person participates using a broadband communication system. A personal communication module may be coupled to a user's communication device and a broadband communication network for capturing data and performing voice recognition associated with a communication. Data may be stored in a database and searched including, for example, keywords from the communications, date, time, number, etc.

Abstract: The present invention permits a user to conduct remote transactions without a network while using an untrusted computing device, such as a hand-held personal digital assistant or a laptop computer. The computing device is augmented with a smartcard reader, and the user obtains a smartcard and connects it to the device. This design can be used by an untrusted user to perform financial transactions, such as placing bets on the outcome of a probabilistic computation. Protocols are presented for adding (purchasing) or removing (selling) value on the smartcard, again without requiring a network connection. Using the instant protocols, neither the user nor the entity issuing the smartcards can benefit from cheating.
