ENC Security ENC Security, while created especially for Sandisk products, enhances the functionality of your Sandisk USB devices by incorporating cross-device cloud-based content encryption. Interesting: Gilbert Vernam | Stream cipher | Claude Shannon | Cryptographically secure pseudorandom number generator However, practical problems have prevented one-time pads from being widely used. It has also been proven that any cipher with the perfect secrecy property must use keys with effectively the same requirements as OTP keys. If the key is truly random, at least as long as the plaintext, never reused in whole or in part, and kept completely secret, the resulting ciphertext will be impossible to decrypt or break. Then, each bit or character of the plaintext is encrypted by combining it with the corresponding bit or character from the pad using modular addition. In this technique, a plaintext is paired with random, secret key (or pad). In cryptography, a one-time pad ( OTP) is an encryption technique that cannot be cracked if used correctly. It's probably fine for general use as long as the NSA isn't after you, but if you have the option to install additional software I'd go with TrueCrypt. As it's a closed-source application and I can't find any info about their implementation, I really can't say anything about it. On the other hand they say a new 2.0 feature is "Edit documents stored in “vault”", so maybe they found away around that, though any method that comes to mind either requires administrative privileges or is really hacky.Īs for the security of the actual encryption, 128bit AES is perfectly secure, assuming it's used correctly. This is fine for securing files against loss of the stick, but forces you take them out of the vault to access them, thereby creating unencrypted copies each time. The usual issue with these tools is that you can only store/retrieve files in the "vault", but not open them while inside. I haven't personally used it, so I can only guess based on the description.
