U disk encryption principle how much do you know

U disk to take the data protection technology is generally divided into two kinds: one is software encryption, one is hardware encryption, about two encryption measures, what is the difference between them? Here we want to say the principle of U disk encryption.

In simple terms, hardware encryption technology generally refers to the use of AES 128-bit or 256-bit hardware data encryption technology to encrypt the product hardware, with the prevention of violent cracking, password guessing, data recovery and other functions. and software encryption is through the product built-in encryption software to achieve the encryption function of the storage device. At the same time, hardware encryption methods are mainly keyboard-type encryption, card-type encryption, fingerprint encryption and so on. and software encryption is mainly password encryption, certificate encryption, CD-ROM encryption.

Of course, both encryption methods have their own advantages and disadvantages, hardware encryption than software encryption in the data security has a higher reliability, 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. And from a security standpoint, software encryption is more easily cracked, now there are many violent cracking software can easily crack software encryption, and hardware encryption because the encryption technology is solidified in the hardware control chip, the entire encryption process has not left any traces in the computer, the password transmission process is also in the form of ciphertext transfer, So it is difficult to intercept the trojan, even if the interception is garbled, so the possibility of cracking is very low.

Know the encryption principle of U disk, I believe that we also compare the advantages and disadvantages of the two encryption methods, for their own U disk is suitable for which encryption, which is different from each other. If you choose Software encryption, small part of the proposal to select a number of professional U disk encryption software, of course, if it is very important file or recommend the choice of hardware encryption is advisable.
