Public Key Cryptography

Cryptography is the gold standard for security. It is used to protect the transmission and storage of data between two parties by encrypting it into an unreadable format. Cryptography has enabled the first wave of secure transmissions, which has helped fuel the growth of transactions like shopping, banking, and finance over the world's biggest public network, the Internet. Many Internet applications such as e-mail, databases, and browsers store a tremendous amount of personal and financial information, but frequently the data is left unprotected. Traditional network security is frequently less effective at preventing hackers from accessing this data. For instance, once-private databases are now completely exposed on the Internet. It turns out that ge...

The cryptosystems based on the Integer Factorization Problem (IFP), the Discrete Logarithm Problem (DLP) and the Elliptic Curve Discrete Logarithm Problem (ECDLP) are essentially the only three types of practical public-key cryptosystems in use. The security of these cryptosystems relies heavily on these three infeasible problems, as no polynomial-time algorithms exist for them so far. However, polynomial-time quantum algorithms for IFP, DLP and ECDLP do exist, provided that a practical quantum computer exists.Quantum Attacks on Public-Key Cryptosystems presemts almost allknown quantum computing based attacks on public-key cryptosystems, with an emphasis on quantum algorithms for IFP, DLP, and ECDLP. It also discusses some quantum resistant cryptosys...
