또한, 127-비트 LFSR 내부 상태에서 랜덤한 이진수열의 홀수 탭과 짝수 탭을 각각 30개씩 취하여서 상호 XOR시키는 랭포드 변형 형태로 재구성함으로써 최종적인 30비트 랜덤한 출력을 생성한다. 
그래서, 이러한 30비트 랜덤한 이진값을 9자리 십진수로 변환함으로써 최종적인 OTP-9자리의 일회용 비밀번호를 생성하는 것을 특징으로 한다. 
따라서, 이를 통해 60비트 랜덤한 LFSR 탭의 XOR 배열을 이용하여 10 9  수준으로 보안성을 높임으로써, 결과적으로 해커가 공격할 수 있는 경우의 수를 1000배 정도 늘리면서 보안성을 높인다.

Abstract: The present invention relates to a fishing hook used for long-line fishing of a sea eel. The fishing hook comprises: a hook shank extending downward by a predetermined length from a hook eye to which a fishing line is fastened; a middle curve formed to be turned or curved in an ″U″ shape from a lower end side to a front side of the hook shank; a hook tip formed by sharpening an upper end portion at the front of the middle curve; and a barb formed inside the hook tip. The fishing hook further comprises a rear curved part that protrudes in the shape of ″)″ by a predetermined width toward a rear side between a vertically extending central side of the hook shank and the middle curve. The middle curve is formed continuously with a lower end side of the rear curved part. Meanwhile, the hook tip is formed to be inclined at a predetermined angle toward the front, at a position higher than an existing fishing hook so as to prevent a young sea eel less than 35 centimeters in length from, which is prohibited from catching by the Fisheries Resource Management Act, from easily swallowing the fishing hook at once. Even when the young sea eel swallows the fishing hook while eating a bait, the young sea ell may immediately feel irritation and spit out the fishing hook, and during spitting out the fishing hook, an end of the hook tip is prevented from being inserted into the inside of the mouth of the young sea eel, and thus, the fishing hook can easily come out from the young sea eel. Accordingly, it is possible to minimize the phenomenon of indiscreetly overfishing young sea eels and inconvenience of sorting young sea eels from among the caught sea eels and removing a fish hook from a young sea eel.
