Present Drawbacks

Drawback of USB flash drives is it’s small size cause of which it can easily be misplaced or lost.

In Cloud Storages the data can be stolen or misused if the username and password of an account to access the storage is hacked by someone.

There are many more drawbacks like limited storage, no security, back up, temp files, no remote disable etc.

Technology

AES (Advanced Encryption Standard) - Established by

the U.S NIST in 2001.

AES is a symmetric-key algorithm.

AES is a variant of encryption family which has fixed

block size of 128,192, or 256-bits.

AES operates on a 4*4 matrix of bytes, termed as ‘state’

.

Key size used for an AES cryptograph specifies the

number of repetitions of transformation rounds that are

required to convert input in plain text into output in

cryptograph text. 8 March 201512
