Edge Tech Corp’s DiskGo Guardian flash drive utilizes The Advanced Encryption Standard (AES) which is a strong encryption algorithm that is commonly used worldwide. AES uses three different key sizes of 128 bits, 192 bits and 256 bits. The Guardian uses a 256 bit key, which is called AES256 and currently considered the strongest mathematical encryption algorithm in use.
AES was adopted from the Rijndael encryption algorithm and was chosen by The National Institute of Standards and Technology (NIST), which is a federal technology agency that develops and promotes standards. AES is fast, secure and is less resource intensive than other encryption algorithms.
By trying every possible key, such as in a brute force attack, it would take “far longer than the age of the universe to complete.” When the AES process was completed, a scientist by the name of Bruce Schneier that was competing with the Rijndael team said in a quote, “I do not believe that anyone will ever discover an attack that will allow someone to read Rijndael traffic.”
Now, with all of this being said, the weakness in this method is the user’s password. It is much more likely for a hacker to crack the password on the unit than the encryption algorithm. The Guardian requires a strong password which requires uppercase letter, lowercase letters and symbols to be used. An example of a strong password is Edg3Te(h. Do not use cognitive passwords since they can be easily detected through the use of password cracking programs.
