Abstract: A system, method, and program for managing a user key used to sign a message for a data processing system having an encryption chip are disclosed. A user is assigned a user key. In order to encrypt and send messages to a recipient(s), the messages are encrypted with the user key. The user key, in turn, is encrypted with an associated key. The associated key is further encrypted using an encryption chip key stored on the encryption chip. The encrypted messages are communicated to a recipient to validate an association of the user with the encrypted messages. The associated key is decrypted with the encryption chip key. The user key is decrypted with the associated key, and the messages are decrypted with the user key. Thereafter, validation of the association of messages with the user is removed by revoking the associated key. In a preferred embodiment, encryption resources are centralized in a server system having the encryption chip.

Abstract: A new fiber optic connector housing and a new fiber optic receptacle, both of which conform to a new standard proposed by the X3T9.3 committee of the American National Standards Institute, are disclosed. In addition, four accessory devices for electro-optic modules, each of which includes one or more essentially conventional plug frames which fit into either one or more conventional, individual fiber optic connector housings or the new fiber optic connector housing, are disclosed.

Abstract: An optoelectronic assembly which provides for enhanced alignment between the internal components thereof. The assembly includes a housing having a base portion and a cover portion, the housing including therein a circuitized substrate. A pair of optoelectronic devices (transmitter and receiver components) are initially movably (loosely) positioned within the housing. The invention utilizes an alignment member which is secured to the housing while positively engaging the movably positioned devices and precisely align these devices with respect thereto such that these devices are in turn precisely aligned with optic means (e.g., a duplex optical connector) when the optic means is positioned within the alignment member. In one embodiment, the housing is of metallic material while the alignment member is a molded plastic structure. The alignment member may also include shutter means therein for safety purposes.
