A remote gaming system whereby a player can gamble against a wagering establishment or state-run lottery from a remote location on a personal computer or portable computer device where it is unnecessary to establish an on-line connection with a host computer associated with the wagering establishment, the gaming computer having associated gaming software for providing at least one wagering opportunity and enabling the player to obtain gambling credit and cash-out any resulting winnings, the host computer enabling the player to purchase and redeem gambling credit at the remote location in one embodiment of the invention using cryptographic protocols such as through a series of authenticatable message exchanges between the player and the wagering establishment, the gaming computer and the host computer directly on-line, or the gaming computer having a detachable tamper-resistant or tamper-evident credit module associated therewith or for use with a personal computer being provided to the player with preinstalled or preloaded gambling credit, the gaming system also enabling participation in future events of which the outcome is uncertain such as, for example, a lottery whereby the player makes selections on a gaming computer at a remote location.

Secure improved remote gaming system

The invention provides a cryptographic apparatus which may be "personalized" to its owner. The apparatus may be utilized by its owner to identify himself to an external computer system, to perform various financial transactions with an external system, and to provide various kinds of credentials to an external system. The apparatus, in one embodiment, is separable into a cryptographic device, packaged in a tamper resistant housing, and a personal terminal device. The cryptographic device includes interface circuitry to permit information exchange with the external system, a memory device for storage of data necessary to allow identification of the owner, and control logic for controlling the exchange of data with the external system to identify the owner. Certain data which must be utilized to perform the identification information exchange is stored in the memory device in encrypted form. The decryption of this data requires the entry of a secret ID, known to the owner. The personal terminal device includes a data entry capability to allow the owner to enter his secret ID. Certain embodiments of the personal terminal device include data display capability to provide transaction information to the owner. Other embodiments include memory devices and a processor to allow storage and manipulation of relatively unsecured data of the owner.

Method and apparatus for remote gaming

A client workstation provides a login address as an anonymous ftp (file transfer protocol) request, and a password as a user's e-mail address. A destination server compares the user's e-mail address provided as a password to a list of authorized users' addresses. If the user's e-mail address is located on the list of authorized users' addresses maintained by the destination server, the destination server generates a random number (X), and encrypts the random number in an ASCII representation using encryption techniques provided by the Internet Privacy Enhanced Mail (PEM) procedures. The encrypted random number is stored in a file as the user's anonymous directory. The server further establishes the encrypted random number as one-time password for the user. The client workstation initiates an ftp request to obtain the encrypted PEM random number as a file transfer (ftp) request from the destination server. The destination server then sends the PEM encrypted password random number, as an ftp file, over the Internet to the client workstation. The client workstation decrypts the PEM encrypted file utilizing the user's private RSA key, in accordance with established PEM decryption techniques. The client workstation then provides the destination server with the decrypted random number password, which is sent in the clear over the Internet, to login to the destination server. Upon receipt of the decrypted random number password, the destination server permits the user to login to the anonymous directory, thereby completing the user authentication procedure and accomplishing login.

A computer terminal device includes a flat screen display element and a touch-sensitive element. Simulated keyboards can be displayed on the display element and, in response to the touching of the simulated keys, generate appropriate control signals. The same flat screen display can also be used to display computer output, either the result of calculations or the result of information retrieval requests. The slim silhouette of this terminal makes it ideal for hostile environments such as the factory floor or the hospital room.

The specification discloses a system and method for authenticating a message recipient prior to transmission of a message and for authenticating the message content after receipt of the message. A randomized character or character sequence is initially enciphered at the authenticator station and stored. The enciphered character is transmitted to the message recipient. The enciphered character is deciphered by the message recipient to reproduce the randomized character. The randomized character is reenciphered by the message recipient and transmitted back to the authenticator station. The reenciphered character is deciphered and the stored randomized character is compared with the deciphered character. The message recipient is authenticated if the stored randomized character exactly compares with the deciphered character. In order to authenticate the message after receipt, polynomial block check characters are accumulated from the message. The block check characters are enciphered according to a predetermined enciphering scheme and transmitted to a remote location, along with the message. The message is received at the remote location and polynomial block check characters are accumulated in response to the received message. Enciphered block check characters are received and deciphered according to the reverse of the predetermined enciphering scheme. The accumulated block check characters are compared with the deciphered block check characters and the message is authenticated if the compared characters are the same.
