Toshiba announces availability of the world’s first series of Self-Encrypting Drives (SED)
Toshiba announced the availability of the world’s first series of Self-Encrypting Drives (SED) equipped with Wipe Technology, a proprietary set of security features that offer new levels of data protection to IT equipment.
The all new Wipe Technology allows users to determine a range of security settings, including invalidation of encryption keys and data invalidation when a drive is removed from its housing or connected to an unauthorized host system.
Toshiba offers 5 new models in the 2.5-type MK6461GSYG family ranging from 160GB to 640GB, with some samples available at the end of April with mass production following at the end of June.
Data invalidation can be achieved in multiple ways:
1. Invalidation of all data by the system
This invalidates all data. This feature is designed for use prior to system disposal or re-purposing to ensure that private data never leaves the control of the responsible business unit or the IT department.
2. Invalidation of data on powering down
The HDD encryption key is automatically invalidated when the drive’s power supply is turned off. If a Wipe Technology SED drive is removed from a system, it can be set to invalidate all data on the drive.
3. Invalidation of data when the equipment is connected to an unauthorized system (The new technology which was added this time)
When an SED HDD is inserted into a system it triggers “challenge response”authentication to confirm the system is known to the HDD. If the authentication fails, the HDD automatically deletes the encryption key. This level counteracts attempts to read a drive by physically removing it from a secure host system and installing it in another system.
