Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for use in a secure data communicaton system includes a microcomputer that controls a cipher process by which sensistive data is encrypted before trans-mission.  When activated, the apparatus accepts either clear-text or ciphertext and transforms the text to its opposite form according to an algorithm that is past dependent and which is also dependent on a pseudo random cipher key.          Ciphertext may then be stored in an information retrieval system or transmitted to a destination terminal where the text is deciphered in real time by a corresponding second apparatus that stores the same key.  In either case, security of transmitted and stored data is maintained since the sensi-tive data is in encrypted form.  A set of logical instructions according to the algorithm is stored in a read only memory of the microcomputer which includes an EPROM unit having a data field of predetermined characters.  The cipher process is initiated by a control character and starts with predeter-mined seeds that establish a first origin in the data field for each line of text to be encrypted.  This origin is then translated to a second origin of the data field in response to four characters that are randomly generated by a counter.          A variable sequence of iterative logical operations trans-forms cleartext to ciphertext and provides a key stream that is non-linear, random-like and which possesses an encryption period that is substantially longer than the period of any line so that the periodicity of the key stream is never indicated.  The cipher keys for each line of text are tempo-rarily stored in a read/write memory to permit editing operations and are erased at the onset of the next line.

Abstract: DIE FOR SPLINING POWER TRANSMISSION MEMBERS    ABSTRACT OF THE DISCLOSURE           A die for splining annular thin wall power trans-mission members in a manner that provides precise spline formation and accurately maintains the roundness of the splined members.  A toothed pinion type mandrel of splining apparatus mounts a power transmission member to be splined between a pair of the dies.  Each die has at least one first tooth group and a second tooth group, and teeth of each tooth group are spaced therealong with the teeth of the first group spaced farther from each other than the , teeth of the second group.  Driving of the dies relative to each other and the power transmission member mounted on the mandrel initially engages the farther spaced teeth with the mounted transmission member so as to cooperate in a meshing relationship with the toothed mandrel with the power transmission member therebetween to form a first set of splines.  Subsequent movement of the dies engages the closer spaced teeth with the power transmission member to mesh with the first set of splines therein while concomitantly cooperating in a meshing relationship with the toothed mandrel with the power transmission member therebetween to form a second set of splines intermediate the first set of splines.  Still subsequent driving movement of the dies again engages the splined power transmission member with the farther spaced teeth to mesh with the splines while skipping at least alternating locations therebetween to correct any out of roundness of the member.  Annular power transmission members which include an end wall and a thin wall sleeve portion with an open end opposite the end wall are splined by two preferred embodiments disclosed.  Each preferred embodiment incorporates a pair of elongated gear rack type dies that are driven rectilinearly on opposite sides of the mandrel mounted member.  Partial teeth are located between the teeth of the first tooth group in an alternating relationship so that the full teeth of the first tooth group are spaced twice as far from each other as the teeth of the second group.  The partial teeth form end depressions between the first set of splines at the open end of the sleeve portion to maintain its diameter the same adjacent the open end as adjacent the end wall.  In one preferred embodiment, the dies are reciprocably driven and subsequently mesh again with the first tooth group that forms the first set of splines so as to thereby correct any out of roundness of the splined member.  In the other preferred embodiment, another tooth group trails the second tooth group and has teeth spaced twice as far from each other as the teeth of the second group so that the out of roundness correction can be provided with the dies driven relative to each other in a single direction.
