Computer encryption is vital for protecting users, data, and infrastructure in the digital age. Using traditional computing, even common desktop encryption could take decades for specialized ‘crackers’ to break and government and infrastructure-grade encryption would take billions of times longer. In light of these facts, it may seem that today’s computer cryptography is a rock-solid way …
This book provides state-of-the-art coverage of the principles, techniques, and management of issues in cyber security, including threat attacks, privacy, signature and encryption schemes. One of the most important topics addressed concerns lightweight solutions for public key encryption in resource-constrained environments; the book highlights the latest developments in this area. Authenticati…
Abstrak: Usaha untuk meningkatkan keamanan sistem informasi melalui autentikasi pengguna yang aman menjadi penting untuk memastikan privasi pengguna sekaligus memverifikasi akses yang sah ke layanan. Autentikasi berbasis kata sandi atau password based encryption (PBE) merupakan metode yang paling banyak diterima dan hemat biaya, tetapi rentan terhadap serangan password-cracking dan database l…
Perimeter defenses guarding your network aren’t as secure as you might think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. This practical book introduces you to the zero trust model, a method that treats all hosts as if they’re internet-facing, and considers the entire network to be c…

This book is an introduction to the implementation of cryptosystems at that level. The aforementioned arithmetic is mostly the arithmetic of finite fields, and the book is essentially one on the arithmetic of prime fields and binary fields in the context of cryptography. The book has three main parts. The first part is on generic algorithms and hardware architectures for the basic arithmetic op…
Enkripsi menjadi salah satu cara untuk mengamankan data, sehingga hanya dapat diakses oleh pihak yang dituju. Terdapat kondisi ketika penerima pesan terenkripsi hanya diperbolehkan mengakses sebagian dari pesan terenkripsi. Kondisi ini disebut sebagai kondisi yang membutuhkan adanya pembatasan akses. Hal tersebut merupakan keterbatasan yang dimiliki oleh Public Key Encryption (PKE) konvensional…
Cryptography is, quite simply, what makes security and privacy in the digital world possible. Tech professionals, including programmers, IT admins, and security analysts, need to understand how cryptography works to protect users, data, and assets. Implementing Cryptography Using Python will teach you the essentials, so you can apply proven cryptographic tools to secure your applications and sy…
Cryptology for Engineers is a study of digital security in communications systems. The book covers the cryptographical functionalities of ciphering, hash generation, digital signature generation, key management and random number generation, with a clear sense of the mathematical background on the one hand and engineers' requirements on the other. Numerous examples computable by hand or with a s…
