Title: Key distribution method
Inventor: OKAMOTO EIJI
IPC: H04L9/08
Filed: 1987-08-24
Granted: 1991-01-29
Abstract: ABSTRACT           The invention relates to a method of distributing a key for enciphering an unenciphered or plaintext message and for deciphering the enciphered message.  A prior art key distribution system has disadvantages in that since it needs a large amount of public information corresponding to respective conversers, the amount of the public information increases as the number of conversers increases.  Further, strict control of such inform-ation becomes necessary to prevent the information from being tampered.  A key distribution method according to the invention is free from the above-mentioned disadvantages of the prior art system.  According to an aspect of the invention, there is pro-vided a method which comprises the following steps:  generating a first random number in a first system; generating first key distribution information in the first system by applying a pre-determined first transformation to the first random number on the basis of first secret information known only by the first system; transmitting the first key distribution information to a second system via a communication channel; receiving the first key distribution information in the second system; generating a second random number in the second system; generating second key distribution information by applying the predetermined first transformation to the second random number on the basis of second secret information known only by the second system; transmitting the second key distribution information to the first system via the channel; receiving the second key distribution information in the first system; and generating an enciphering key in the first system by applying a predetermined second transformation to the second key distribution information on the basis of the first random number and identification information of the second system which is not secret.

Granted: 1992-08-25
Abstract: SWING FORCE INDICATOR FOR A PLAYING PIECE            OF SPORTS EQUIPMENT      ABSTRACT    A swing-force indicator for a playing piece of sports equipment intended to be swung in the playing of a game, including an elongate housing, an elongate shaft, and bearings disposed adjacent opposite ends of the housing for mounting the shaft for lengthwise turn-ing movement therein. A manually engageable finger piece is rigid on one end of the shaft, and a weight member having an indicator is slidable along the shaft. A com-pression spring on the shaft engages the weight member to bias it toward one end of the shaft, to a starting position. The weight member has a pawl and the shaft has teeth cooperable with the pawl to hold the weight member in various adjusted positions remote from the starting position against the action of the compression spring.          The shaft has a smooth track on which the pawl can al-ternately ride when the shaft is turned by the finger piece, thereby to enable return of the weight member to a starting position under the action of the compression spring. There is provided a resilient detent finger in the housing for yieldably holding the shaft in position for engagement of the teeth thereof by the pawl. The advantage of the present construction over the devices of the prior art is that reduced cost is realized, due to a simplification in the assembly of the individual components.
