Since the proposed mechanism encrypts the whole disk using the hash value of the user PW, an attacker who does not have the correct password or the hash value of the PW cannot obtain the correct decryption key and thus cannot
decrypt the disk.
When a user powers on a machine and enters the key to
decrypt the drive, the drive is then re-encrypted when the machine is powered off.
"More modern ransomware families, collectively categorised as crypto-ransomware, encrypt certain file types on infected systems and forces users to pay the ransom through certain online payment methods to get a
decrypt key."
In our proposed schemes chaotic maps have been used instead of random phases as random keys which achieved high dynamic range for the key image through the flexibility in changing the parameters as well as initial conditions of the proposed chaotic map which made it difficult for the attacker to
decrypt an unknown image in a strong manner from the practical point of view.
Chapel Hill, NC, November 23, 2016 --(PR.com)-- ApexSQL, a Microsoft Gold Certified Partner and a major provider of Microsoft SQL Server solutions, announced the release of a new product - ApexSQL
Decrypt 2017.
The petition said that in order to
decrypt any message on WhatsApp, one would need a whopping 115,792,089,237,316,195,423,570,985,008,687,907,853,269,984,665,640,564,039,457,584,007,913,129,639,935 key combinations, which is almost impossible for even a super computer.
"Since a handful of primes are so widely reused, the payoff, in terms of connections they could
decrypt, would be enormous," researchers Alex Halderman and Nadia Heninger wrote in a blog post published.
The new tool offers multiple local and cloud acquisition options, enabling experts to extract and
decrypt WhatsApp data from iTunes, iCloud and WhatsApp proprietary backups.
The users can download the encrypted data from the cloud storage,
decrypt them, and can share it with other members in the group.
