Device Serialization Makes Fortasa Flash Cards and SSDs More Secure

Many of our industrial and military customers have a high level of interest to protect the critical information that is stored on their SSD or Flash card. A typical solution is to purchase a shrink wrap Encryption software application package that will encrypt the stored data. This level of encryption uses only the private key (password) to encrypt the stored files.The encrypted files can be copied and drives duplicated, but regardless of the storage medium the files will only be decrypted and useful to the owner of the encryption key.

Secure Encrypted Files

This solution works well as long as the private key is not publicly shared. If, however, the encryption key is released in the public domain, the SSD can be easily duplicated, files decrypted and easily shared.

Flash SSD Easy and Secure Data Erase

Many computing applications require high level of data protection and security. When the system security is breached, the logical requirement is to purge or destroy the stored data quickly and efficiently before unauthorized access takes place.

SSD Efficient Data Destruction

However, secure data erasure is not a trivial task. Popular operating systems have been developed specifically to protect and not destroy the user data. Conventional "recycle" folder or "unerase" command give the user an easy way to restore a file that was wrongfully deleted.

Flash Drive Hidden Zones - Undetectable Security Feature

Oftentimes there is a need to keep secure data away from public eyes. Traditionally the most common way to protect critical information on hard disk drives (HDDs) has been to encrypt it with a strong key. While the data is protected from the unauthorized access and duplication, it is still fully visible to anyone checking the drive contents. Unlike HDDs, in Flash cards and SSDs the data access can be restricted by the unique Flash Controller firmware functionality to not only encrypt, but also hide the data from the visible partition.

This capability to achieve securely hidden information is enabled in Fortasa Memory Systems Solid State Storage products. Select Fortasa devices offer user established protection zones. These zones are initially defined at the manufacturing facility by a device utility and can be set to any starting and ending LBA location. Once the zone is set it can be configured to one of the three definitions:

1) Unprotected - Fully Visible and Accessible by Read and Write Command
