The encryption key could be derived from the decryption key as easily as vice versa.
But unlike OTR, Crypto.cat allows up to 21 people to chat using the same encryption key, and it requires only Web access.

In addition, the encryption key for each call is known only to the computers participating in the call, not to Skype itself.

And since Silent Circle doesn't host the required encryption key on its servers, there's no way for the company to access users' data.
The encryption of such messages is vulnerable because the default encryption key is not unique to a BlackBerry but the same for all BlackBerrys.

For best protection, Ozancin recommends two-factor authentication3: adding an additional security mechanism to the password one such as a smart card or an encryption key pair.
Adding PUF technology significantly improves the chip's protection from reverse engineering attacks, as it removes the permanent presence of the digital encryption key on the device.

For example, an icon similar to the SSL encryption key-prevalent in e-commerce transactions-may pop up to indicate that a site matches a user's privacy tolerance level.
From the point of view of copyright holders, though, the necessity to use an encryption key does act as valuable friction against a file being shared too freely.

As such, this content after start-up can serve as a unique fingerprint, which can then be used as a key to protect an encryption key or to protect a memory.

Many factors are at play here dealing with individual or third-party data retention policies sometimes beyond your control as well as continued usage of the same private encryption key and password.
Since your bits may travel through an upstairs apartment or the house next door, HomePlug uses a networkwide password as an encryption key to keep your data invisible to neighbors' prying eyes.
In addition 128 bit AES encryption provides data protection and in particular can be used to rapidly erase the encryption key so the drive can be repurposed without concern about the old data being accessible.

On Tuesday, Digg announced it had removed user-submitted links to articles containing the HD-DVD encryption key, a series of 16 digits that programmers could use to crack the copy protection code on the new disc format.
PUFs are an innovative way of safeguarding individual chips from data theft by using the unique 'fingerprint' inherent in every semiconductor device to protect its encryption key, making it very hard to clone and thus reverse-engineer and compromise security microcontrollers.

Tuesday afternoon, Digg CEO Jay Adelson had posted a message on his blog explaining that the site was removing links to articles that featured the newly cracked HD-DVD encryption key, which can be used to decrypt the high-definition discs and copy their content.
Yesterday, Symantec was lagging in encryption and key management and today, with PGP and GuardianEdge, it is now able to provide leading solutions worldwide.

In addition, the amendment makes no mention of controls on the domestic use of encryption products and does not include any language covering encryption-key recovery or key escrow.
It turned out he was a world-famous cryptographer, Dr. Whitfield Diffie, a pioneer of public-key encryption that to this day drives the CIA, FBI and others quite nuts.
Imagine Americans giving the key to their encryption software to the Russians.
The government wants vendors to develop encryption software that includes a key recovery mechanism whereby the government could get access to the algorithm to decode a message for law enforcement purposes.
CNN: U.S. government to set new standard for advanced encryption
But for most encryption systems, especially the Public Key systems that are widely used by the banks, you need to know very sophisticated number theory, analytic number theory, elliptical theory.
And for the ultimate in security, AES 256-bit encryption prevents unauthorised file access to the key with password protection.

Before the new regulations, companies were forced to obtain a license from the U.S. government to export encryption products higher than 56 bits in key length.
For instance, requiring encryption software and hardware makers to hold a decoding key in "key escrow" is the equivalent of asking a bank to hold an extra set of safe-deposit-box keys.
At the time, the federal government was also pushing hard to get companies to add so-called "key escrow" type technologies to their encryption products so that law enforcement could obtain access to encrypted data on demand.

On Wednesday, WikiLeaks released a series of video files obtained from UK-based Gamma that show how its products can be used to monitor Wifi networks from a hotel lobby, hack cell phones and PCs with fake software updates, or infect computers from a USB key to intercept Skype conversations, log encryption passwords and read private files.
