HSM offers a high level of key security

                        Abstract

Cryptography is the art and science of keeping message secure, it has become an essential part of everyday life in today's electronic world. Hardware-based cryptography is more fast and more security than software cryptography. The algorithm and all private keys are kept secure in the protected memory of a tamper-resistant device, commonly referred to as a hardware security module (HSM) It will prevent the key from being stolen and used elsewhere. That means HSMs provide secure management of private keys in that the keys never leave the module unencrypted. The RSA Keon KRM featuring a hardware-based key generation process through a Hardware Security Module (HSM) is an example to show how the HSMs offer a more secure key generation technique than software based generation. However, the cost of HSM is very high and its API is still in its infancy, there still has room for HSM to consummate.
