Hardware Crypto Module Securing Cloud Storages

The Enigma II is a hardware crypto module (HCM) that encrypts existing drive in place and safeguards data confidentiality over Data-In-Transit (DIT) or Data-In-Motion (DIM). Enigma II HCM is capable of encrypting selective files and folders of any computer detectable storage devices including boot drive, external drive such as USB or 1394, network attached drive and virtual drives such as Windows OneDrive, Google's GoogleDrive and Macintoshi iCloud. With the Enigma II HCM, file/folder can be encrypted and decrypted. Without it, the encrypted file/folder remains encrypted. Enigma II HCM further allows the sharing of an encrypted file/folder for as long as the parties possess the same Data Encryption Key (DEK), which can be set through user's Recovery Password of an Enigma II HCM. Unlike its predecessor the Enigma that performs full disk encryption to ANY number of the attached USB Mass Storage Class (MSC) drive, the new Enigma II HCM is the best alternative to your software encryption, encrypting existing drive in place and sending the encrypted files/folders through public network with confidentiality. Only the recipient who has possessed the same keyed Enigma II HCM can successfully decrypt those received encrypted files and folders.

NIST Certified Real-time Hardware Crypto Engine

The cryptographic performance is performed by the NIST (National Institute of Standard and Technology) certified real-time hardware engine and the data encryption key remains in the HCM until the next power on cycle – the solution is secure and requires no additional user training. Enigma II HCM can encrypt files/folders of any number of those detectable drives through the provided software GUI of Windows and Macintosh. However, the Enigma II HCM is not engineered to perform real-time full disk encryption like its predecessors but the selective file/folder therefore one may experience slower performance while encrypting big file/folder (over 2GB per file/folder). For full disk encryption application, choose the Enigma I or other X-Wall based real-time crypto modules from
