Fundamental flaws in the encryption system used by popular solid-state drives (SSDs) can be exploited by miscreants to easily decrypt data, once they've got their hands on the equipment.

A paper [PDF] drawn up by researchers Carlo Meijer and Bernard van Gastel at Radboud University in the Netherlands, and made public today, describes these critical weaknesses. The bottom line is: the drives require a password to encrypt and decrypt their contents, however this password can be bypassed, allowing crooks and snoops to access ciphered data.
