Abstract

Nomor Pokok Wajib Pajak (NPWP) is the 20 distinct code characteristics that are confidential only to the taxpayer when it comes to making tax transactions. The many tax payers who use NPWP others in their business activities make NPWP a very important aspect of maintaining confidentiality and the authenticity of their data. Therefore, solutions are needed that can be used to make the necessary information secure. Cryptography involves the secret science of code writing using certain mathematical models.The study discusses NPWP encryption using a combination algorithm One Time Pad (OTP) and an operation Exclusive-OR (XOR). The encryption process involves generating random numbers for an OTP algorithm, after which it is followed by an XOR operation. The key on XOR encryption is generated from an algorithm generating random numbers Blum Blum Shub. Encryption keys generated as much as the number of plaquic characters. The encryption keys used by each character would vary and not occur again. Therefore, ciphertext results from an encrypted process using an OTP algorithm and an XOR operation more complicated and more difficult to decipher by crypts.
npwp 加密算法结合使用了单次填充算法和排他-或运算
Nomor Pokok Wajib Pajak(NPWP)是 20 个不同的代码特征,只有纳税人在进行税务交易时才会对其保密。许多纳税人在其商业活动中使用 NPWP,这使得 NPWP 成为维护其数据保密性和真实性的一个非常重要的方面。因此,需要有能够确保必要信息安全的解决方案。密码学是一门使用特定数学模型编写代码的秘密科学。本研究讨论的是使用 "一次性密码"(OTP)和 "排他性-OR"(XOR)运算组合算法对 NPWP 进行加密。加密过程包括为 OTP 算法生成随机数,然后进行 XOR 运算。XOR 加密的密钥由随机数布勒姆-布勒姆-舒布算法生成。生成的加密密钥与 Plaquic 字符的数量一样多。每个字符使用的加密密钥各不相同,不会重复出现。因此,使用 OTP 算法和 XOR 运算的加密过程产生的密文更加复杂,密码解密更加困难。
