摘要： A system, method, and article of manufacture are provided for pricing a cryptographic service on a network utilizing one or more cryptoservers. A request for a cryptographic service is received from a user utilizing a network. The request is received by a cryptographic service provider. A contract is generated based on a variable pricing scheme in response to the request. The contract is sent from the cryptographic service provider to the user utilizing the network. A method is also provided for auditing a security provision on a network utilizing a cryptoserver. A cryptographic key is obtained such as by obtaining it from a trusted source or generating the key. A plurality of users are allowed to request that a cryptoserver use the cryptographic key to sign a message in violation of a security provision. It is determined whether the cryptoserver signed the message in response to the request. An indication of failed security integrity is provided upon determining that the cryptographic server has signed the message.

摘要： A system for controlling access to online content referenced in a hardcopy document. A user requesting access to online content available on a server responds to an authentication challenge from the server using a password mechanism printed in the hardcopy document. The password mechanism allows the user to identify a password for responding to an authentication request by the server. After authenticating the user, the server initiates a state change to enable subsequent access to the online content by the user with a different password that is also identified with the password mechanism.

摘要： A symmetric key encryption system includes a printer or copier for performing decryption in two passes. During a first pass an encrypted image is decrypted to define a first partially decrypted image and during a second pass a complement of the encrypted image is decrypted to define a second partially decrypted image. The first partially decrypted image is formed when the encrypted image is rendered onto a first recording medium through a stencil. The stencil, which is a random arrangement of holes, is overlaid on the first recording medium to permit only selected portions of the encrypted image to be rendered on the recording medium. During the second pass, the complement of the encrypted image is rendered on a second recording medium through a complement of the stencil to yield the second partially decrypted image. Overlaying and aligning the first partially decrypted image and the second partially decrypted image finally decrypts the encrypted image.
