USB disk Data encryption of the general method

U disk almost one person, many people use it to store their own important data. For this reason, U disk brings convenience to us, but also brings data security problems. So in the storage of important data we generally have to encrypt u disk. Now let's see what types of encryption are.

Encryption can be divided into two types, namely, hardware encryption and software encryption.

1: What is the difference between hardware and software encryption

Hardware encryption for keyboard encryption, card-type encryption, fingerprint encryption and so on. and software encryption is mainly password encryption, certificate encryption, CD-ROM encryption.

2: Commonly used software encryption type

In short, both have their own advantages. Hardware encryption is more reliable than software encryption in data security, and Plug and Play, no need to install encryption password software, more convenient to use. and software encryption in technology and cost less than hardware encryption, easy to achieve, cost-effective. Therefore the market uses the software to encrypt the product to be compared to the hardware encryption product the price is low.

3: Hardware encryption and software encryption comparison

From a security point of view, software encryption than hardware encryption is more easily cracked, such as brute force cracking software, the product format, the storage of data flash chip removal and other extreme ways, can easily crack software encryption. Relatively speaking, hardware encryption because the encryption technology is solidified in the hardware control chip, the entire encryption process left almost no traces on the computer, password transmission process is also in the form of ciphertext transmission, so it is difficult to be hijacked by the Trojan, even if intercepted is garbled, so the possibility of cracking is very low.
