    • A public-key data encryption system employing RSA public-key data encryption including a message encrypter capable of encrypting messages using a non-secret encryption key, a transmitter-receiver coupled to the message encrypter which transmits or receives an encrypted message to or from a remote location, the transmitter-receiver also being coupled to a decrypter capable of decrypting a received encrypted message using a decryption key which is a secret input to the decrypter, and an encryption-decryption key generator, including a microprocessor or other large-scale integrated circuit or circuits formed to generate a sequence of prime numbers beginning with a selected known prime number having a length relatively short with respect to the desired length of the last in the sequence of prime numbers, and which is constructed to form the sequence of prime numbers in the form hP+1 where P is the preceding prime number in the sequence, and to test hP+1 for primality by first determining if hP+1 has a GCD of 1 with x, wherein x is a composite number consisting of the product of all known prime numbers less than or equal to a pre-selected known prime number and if the GCD is not equal to 1, incrementing h to form a new hP+1 to be tested for a GCD equal to 1, and when a GCD is found to be 1, performing the primality tests to determine whether 2.sup.hP .ident.1 [mod (hP+1)] and 2.sup.h .notident.1 [mod (hP+1)], and if either 2.sup.hP .notident.1 [mod (hP+1)] or 2.sup.h .ident.1 [mod (hP+1)] further incrementing h and so on until a prime is found in this manner and then determining if the length of the prime number is of or greater than the desired length. If the hP+1 which has been determined to be prime is not of the desired length, hP+1 is placed in the sequence of prime numbers and a new h selected to be used to find the next prime number in the sequence in accordance with the above described procedure by forming a new hP+1 in which P is the previously determined prime number in the sequence of prime numbers. When a prime number in the sequence of prime numbers is found which is of the desired length it is input into the encryption-decryption key generator for generating the RSA public-key encryption and decryption keys.

    • A cable clamp assembly and a cable clamp method for a flat fiber optic cable are disclosed. The assembly includes a wedge-shaped outer shell with a bottom wall having a friction inner surface with a longitudinal central recess formed therein. The flat fiber optic cable resides within the interior of the outer shell and is supported by the friction inner surface. A shim having two parallel rows of protrusions fits within the interior of the outer shell with the protrusions being in contact with the fiber optic cable. The assembly includes a wedge insert having two outer ridges that substantially align with the two rows of protrusions. When the wedge insert matingly engages the outer shell, the outer ridges press down on the protrusions, which in turn press down on the fiber optic cable mainly at the locations where longitudinal dielectric strength members reside.
    • 公开了一种用于扁平光缆的电缆夹组件和电缆夹紧方法。 组件包括楔形外壳,其具有底壁,所述底壁具有形成在其中的纵向中心凹部的摩擦内表面。 扁平光缆位于外壳的内部并由摩擦内表面支承。 具有两个平行的突起的垫片装配在外壳的内部中,突起与光纤电缆接触。 组件包括楔形插入物,其具有两个与两排突起物基本对准的外脊。 当楔形插入件配合地接合外壳时,外脊下压到突起上,突起又主要在纵向介电强度构件所在的位置压在光纤电缆上。
