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.
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.
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.
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.

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.

DES, developed by IBM Corp. and adopted by NIST in 1977, has only one key size -- 56 bits, which is the length of the encryption algorithm.

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.
