secure USB drive(redirected from secure pen drive)
secure USB driveA USB drive that stores encrypted data. The encryption may be performed by third-party encryption software or the software that comes with the drive. In either case, the software is configured to encrypt the data before writing to the drive and decrypt after reading.
A more secure approach is to embed the encryption algorithm in a chip within the drive itself, in which case encryption is mandatory for all data on the drive and cannot be disabled. In addition, hardware encryption is much faster than software-based encryption. See USB drive.
|IronKey USB drives are physically hardened and tamper proof. They also prevent the files from being copied to another computer where there is plenty of time to break the code. The drive's chip generates the keys, maintains the retry count and performs encryption/decryption. If the wrong password is entered too many times, it self destructs.
