Its power unit, however, was derived from the reactor of the more modern American nuclear submarine Skipjack.

Skipjack was invented by the National Security Agency of the U. S. Government ; this algorithm was initially classified SECRET, which prevented it from being subjected to peer review from the encryption research community.

The Skipjack algorithm was declassified and published by NSA on June 24, 1998.

In 1998 Skipjack, the encryption algorithm used in Clipper, was declassified.

Skipjack was proposed as the encryption algorithm in a US government-sponsored scheme of key escrow, and the cipher was provided for use in the Clipper chip, implemented in tamperproof hardware.

A truncated differential attack was also published against 28 rounds of Skipjack cipher.

Although incorrect security markings immediately indicated a hoax, there were several features of the code which suggested it might be leaked source code for the Skipjack encryption algorithm, which was still classified at the time.

When Skipjack was eventually declassified in 1998, it was indeed found to be totally unlike S-1.

Beyond the name change, the film's submarine has a design similar to the first nuclear-powered submarine, the, rather than the more streamlined, teardrop-shaped vessel, either the contemporaneous Skipjack or Permit design, that was described in the novel.

Some of the plot points of the movie were based on real-life incidents, such as the sinking of the submarine USS Sealion at the pier at Cavite Navy Yard in the Philippines, Commander Sherman's letter to the supply department on the inexplicable lack of toilet paper ( based on an actual letter to the supply department of Mare Island Naval Shipyard by Lieutenant Commander James Wiggin Coe of the submarine USS Skipjack ), and the need to paint a submarine pink due to the lack of enough red or white lead undercoat paint.

In Brown's novel, Skipjack is proposed as the new public-key encryption standard, along with a back door secretly inserted by the NSA (" a few lines of cunning programming ") which would have allowed them to decrypt Skipjack using a secret password and thereby " read the world's email ".

The United States offered to supply a complete set of propelling equipment like that used in the Skipjack.

Since 1959, Deal Island has hosted an annual Labor Day weekend Skipjack Race.

Labor day of 2010 will be the fifty-first annual Skipjack Race.

The Skipjack encryption algorithm is an example of such a cipher.

For example, MISTY1 is a Feistel cipher using a three-round Feistel network in its round function, Skipjack is a modified Feistel cipher using a Feistel network in its G permutation, and Threefish ( part of Skein ) is a non-Feistel block cipher that uses a Feistel-like MIX function.

The Clipper chip used a data encryption algorithm called Skipjack to transmit information and the Diffie-Hellman key exchange-algorithm to distribute the cryptokeys between the peers.

In cryptography, Skipjack is a block cipher — an algorithm for encryption — developed by the U. S. National Security Agency ( NSA ).

Skipjack's more immediate heritage dates to around 1980, and its initial design to 1987 ... The specific structures included in Skipjack have a long evaluation history, and the cryptographic properties of those structures had many prior years of intense study before the formal process began in 1987.

Skipjack uses an 80-bit key to encrypt or decrypt 64-bit data blocks.

Biham, Shamir and Biryukov's attack continues to be the best cryptanalysis of Skipjack known to the public.

An algorithm named Skipjack forms part of the back-story to Dan Brown's 1998 novel Digital Fortress.

The first part of the road was steep, but it leveled off after the second bend and curled gradually into the valley.

When it was followed by a second, whining even closer, Cobb swerved sharply aside into a depression.

There had been a good second or two during which my muffler had been blowing out, and now I was certain I'd seen her somewhere before.

He was aware of her as a frightfully good-looking American WAC, a second lieutenant assigned to do the paper work, ( regardless of how important she might have thought she was ) in the Command offices, but that was all.

A phony blonde hanging onto a bygone youth and beauty, but irreparably stringy in the neck, she was already working on her second gin and tonic, though it was not yet ten A.M.

Their skin was covered with a thin coating of sweat and dirt which had almost the consistency of a second skin.

The second specific comment was the report of Eisenhower's Commission on National Goals, titled Goals For Americans.

He gave us a simile to explain his admission that even at the worst period of his second illness it never occurred to him there was any renewed question about his running: as in the Battle of the Bulge, he had no fears about the outcome until he read the American newspapers.

Its second press release was on January 15, 1958, and it recommended that the secret papers be destroyed.

But during the second half of the century its fortunes reached a low point and when in 1897 Cyrus H. K. Curtis purchased it -- `` paper, type, and all '' -- for $1,000 it was a 16-page weekly filled with unsigned fiction and initialed miscellany, and with only some 2,000 subscribers.
