Hardware encrypted usb drive

Types of hardware encrypted USB drives

A hardware encrypted USB drive uses its own processor to encrypt and decrypt data. The advantages of hardware encrypted USB drives include faster processing speed and better security than software-encrypted drives.

The types of hardware-encrypted USB drives include self-encrypting drives (SEDs) and tamper-resistant devices.

• Self-encrypting drives (SEDs)

  SED encrypted USB drives automatically encrypt all data using strong encryption algorithms like AES 256-bit. Users are required to input a password or pin to access encrypted data. In addition to encrypting data, SEDs also protect the encryption key through physical security measures. When an unauthorized person inputs the wrong password or tries to access the drive, the SED wipes the stored data. Some SEDs have a FIPS certification showing that they meet federal information processing standards. The self-encrypting USB drive is ideal for devices that need high-performance encryption and large-scale encryption like servers and laptops.

• Tamper-resistant devices

  Tamper-resistant encrypted USBs have extra security features that protect stored data. If someone tries to physically access or damage the device, it alerts the user and erases the stored data. The USB drives are ideal for environments with potential physical security risks.

Functions and Features

Hardware encrypted USB drives have several features that make them safe and effective in keeping confidential data secure. Below are some of the key features of hardware-encrypted USB drives:

• Encryption: The primary characteristic of a hardware-encrypted USB drive is undoubtedly its capacity to encrypt data.

Most models have AES (Advanced Encryption Standard) as the encryption algorithm, especially AES 128-bit or AES 256-bit. The former offers decent encryption suitable for personal or small business use. On the flip side, 256-bit AES is incredibly strong, making it ideal for government agencies or large businesses.
• Independent Encryption: A significant feature of hardware-encrypted drives is their ability to encrypt data independently of the connected systems or devices. This feature ensures that the encryption process is not affected by the configuration or security system of the host system.
• High-Speed Transfer: Since the encryption process is done internally, hardware-encrypted drives offer high-speed data transfer. The fast transfer speeds are particularly advantageous for users who need to move large files or lots of files within a short time.
• Predefined Access: Encrypted USB flash drives have predefined access management systems. Users usually get a pre-defined set of users and their access rights to the drive. In some instances, only those with physical access to the drive can plug it into a system to access the data.
• Portable: Most hardware-encrypted drives are small and lightweight, making them easy to carry around. Their small size enables users to store them internally in their gadgets and only pull them out when needed.
• Fob Software:Many hardware-encrypted drives need to use specific software (fob software) to unlock the drive and access the data. The fob software provides an interface for entering the correct password or pin to unlock the drive. Once unlocked, users can transfer data to and from the drive.
• Backup and Recovery: Some hardware-encrypted drives have a backup and recovery feature. Users can create a backup of the drive's data, which can be useful in case the drive gets damaged or any other issue that may lead to data loss. Moreover, the feature can help users recover the data in case they forget the encryption password or pin.
• Self-Destruction: Encrypted USB drives have a self-destruction feature, which can delete all the data stored if an unauthorized person tries to access it.
• Integrated Fingerprint Scanner: Some hardware-encryption models have an integrated fingerprint scanner that scans the user's fingerprint. The scanned fingerprints provide access to the data stored in the drive.

Usage scenarios of hardware encrypted USB drives

Crypto drives offer a wide range of applications in various sectors and industries. Some of them include the following;

• Medical facilities: These USB drives are used to store patient data, medical records, and sensitive health information. Hardware encrypted memory sticks help keep this information safe, avoiding unauthorized access. They also assist in data transfer between medical practitioners and departments.
• Education institutions: This includes universities, colleges, and even schools. The USBs are used in educators' storage and transfer of confidential data, such as examination papers, student records, and research materials.
• Government agencies: The USBs are used widely in government agencies to safeguard sensitive information like asset encrypted national security data, classified documents, and intelligence information. This is majorly because; physical security of a USB drive that involves pin entry makes them safer than unlocked or unprotected drives.
