The History and Applications of Cryptography

Encryption is research on secure communication or secret communication. Encryption has existed thousands of years ago. Encryption has existed thousands of years ago. Encryption handles authentication, confidentiality, and integrity of data. There are various encryption implementations in the information system. This article describes hashes, encryption, digital signatures, and digital certificates. The history of cryptography can be traced back to the Egyptian hieroglyphs engraved on pyramids and other Egyptian artifacts.

Abstract The purpose of this white paper is to emphasize the importance of encryption. The application of encryption is important for today's lifestyle. As technology evolves, it is important to understand that encryption becomes very common and integrates in various places, from online banking and e-mail privacy to national security. In this article we will focus on general encryption schemes and explain that these technologies may become unusable in the future due to advances in technology and sophisticated decryption technologies. Finally, as factorization is a major part of many common cryptographic techniques, we discuss and analyze mathematics behind decomposition technology. This includes mathematical interpretation of techniques such as the Fermat method and secondary screening. In addition, a concrete example of decomposition technique comparison is shown, and various techniques and necessary computer time are shown.

Encryption is a study of mathematical methods related to information security, such as confidentiality, data integrity, message authentication, and entity authentication (Piper, 2002). Encryption has many uses such as digital communication (communication device, e-mail and data exchange, access control and audit trail, electronic banking), and commercial software key management (software verification and virus detection). Electronic data exchange (EDI) is considering the encryption of electronic information that contracts and purchase orders are electronically signed and delivered. Even at the Bank of England, a similar system is used for POS (Point of Sale) electronic remittance (EFT). For the local area network (L.4N), the IEEE 802.10 LAN Security Working Group is currently creating security standards using public key technology for key management.
