A pseudorandom generator is an easy-to-compute function that stretches a short random string into a much longer string that “looks” just like a random string to any efficient adversary. One immediate application of a pseudorandom generator is the construction of a private key cryptosystem that is secure against chosen plaintext attack. There do not seem to be natural examples of functi…

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…
Public key cryptography was introduced by Diffie and Hellman in 1976, and it was soon followed by concrete instantiations of public-key encryption and signatures; these led to an entirely new field of research with formal definitions and security models. Since then, impressive tools have been developed with seemingly magical properties, including those that exploit the rich structure of pairing…
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…
