In mathematics, particularly in algebra, a field extension is a pair of fields K\subseteq L, such that the operations of K are those of L restricted to K. In this case, L is an extension
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. K
A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of n bits) that has special properties desirable for a
