5.2.5 Infineon Security Platform
Using Infineon Security Platform allows electronic mails and files to be encrypted and
prohibited from being opened without authentication password.
In addition, N22A is equipped with a security chip called TPM (Trusted Platform Module) in its
major part to store encryption keys in the security chip. Thus, if only the HDD is withdrawn, the
data in the HDD will not be read.
