Keys are lost, identity theft if the two computers establish a new SSL session negotiation, they will use digital certificates to verify the identity of each other, exchange key material. The exchange of key material using the network servers public key to encrypt the material. Upon receipt of the encrypted material, the network server with the corresponding private key to decrypt. If the intruder to steal the private key of the server, then it will go wrong. Intruder to obtain a copy of the servers private key, in fact, can be posed as the server, because the operation can now be decrypted, and the successful exchange of the remaining signal processing steps. With the hands of the private key stolen, the thief can create a devastating site, pseudo-legal private key holders identity, not wanton attack unsuspecting users, legal status appears to give a false sense of security. Since the private key security stakes, HSMs purpose is to provide a more secure hardware-based environment in order to save the private key and perform cryptographic operations using the private key. HSM through physical and logical manner, the key material with the use of their computers and applications are isolated in order to reduce the use of vulnerable software way to save the private key associated risks. In addition, anti-destroying physical design, coupled with strict rules to ensure against direct physical attacks and from attacks initiated by internal trusted users.
