Web@curious: DH is totally asymmetric cryptography; it is not asymmetric encryption, but it is still cryptography and it is still asymmetric ("asymmetric" = "not all involved party share the same secret keys"). Digital signatures are also asymmetric cryptography (and I do not talk about them here). WebThe CDH assumption states that, given for a randomly-chosen generator g and random it is computationally intractable to compute the value The security of many cryptosystems is based on the CDH assumption, including notably the Diffie–Hellman key agreement scheme.

WebCryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary. It is theoretically possible to break such a system, but it is infeasible to do so by any known practical means.
