Diffie – Hellman key exchange ( D – H ) is a specific method of exchanging cryptographic keys.

The Rock was a key part of the Allied supply lines to Malta and North Africa and base of the British Navy Force H, and prior to the war the racecourse on the isthmus was converted into an airbase and a concrete runway constructed ( 1938 ).

What is needed is a hash function H ( z, n ) – where z is the key being hashed and n is the number of allowed hash values – such that H ( z, n + 1 ) = H ( z, n ) with probability close to n /( n + 1 ).

Major was Prime Minister during the first Gulf War of 1991, and played a key role in persuading US President George H. W. Bush to support no-fly zones.

For example, one might assume the same security that HMAC provides could be achieved with MAC = H ( key ∥ message ).

The key parts to be aware of are MPEG-4 part 2 ( including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by QuickTime 6 ) and MPEG-4 part 10 ( MPEG-4 AVC / H. 264 or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by QuickTime 7, and by high-definition video media like Blu-ray Disc ).

In 1997, it was publicly disclosed that asymmetric key algorithms were developed by James H. Ellis, Clifford Cocks, and Malcolm Williamson at the Government Communications Headquarters ( GCHQ ) in the UK in 1973.

An almost literal use of the phrase appears in popular fiction within H. G. Wells ' 1933 novel The Shape of Things to Come, where the protagonist finds a manuscript written in shorthand that provides a key to understanding additional scattered material that is sketched out in both longhand and on typewriter.

It was the need to synchronize the scramblers that suggested to James H. Ellis the idea for non-secret encryption which ultimately led to the invention of both the RSA encryption algorithm and Diffie-Hellman key exchange well before either was reinvented publicly by Rivest, Shamir, and Adleman, or by Diffie and Hellman.

The author also wrote pioneering biographies of many key fantasy writers, most as short articles, but two as full-length studies of the prominent authors Robert E. Howard and H. P. Lovecraft, the first major independent biographies of both writers.

" Dunmore gave a key to Lieutenant Henry Colins, commander of H. M. S.

The key was taken from the name of the design and test base: Huntsville, Alabama, giving HUNTSVILE, with duplicated letters dropped: H was used for 1, U for 2, ..., E for 9 and X for 0.

where U is the unicity distance, H ( k ) is the entropy of the key space ( e. g. 128 for 2 < sup > 128 </ sup > equiprobable keys, rather less if the key is a memorized pass-phrase ).

The Board of Fortifications chaired by William H. Taft recommended that key harbors of territories acquired after the Spanish-American War be fortified.

In the DOS version, the cursor keys specify movement, and the fast-move keys ( H, J, K, and L ) are supplanted by use of the scroll lock key.

They are known for extensive use of segues in their live performances, and were considered a key part of the re-emerging jam band scene of the 1990s, spearheading the H. O. R. D. E.

Other Arnold protégés eventually filled key positions in the strategic bombing forces, including Haywood S. Hansell, Laurence S. Kuter, and James H. Doolittle.

* Philo entry in historical sourcebook with fresh translations of key excerpts by Mahlon H. Smith

: HMAC ( K, m ) = H < big >< big >(</ big ></ big >( K ⊕ opad ) ∥ H < big >(</ big >( K ⊕ ipad ) ∥ m < big >)< big >)</ big ></ big >

No known extensions attacks have been found against the current HMAC specification which is defined as H ( key1 ∥ H ( key2 ∥ message )) because the outer application of the hash function masks the intermediate result of the internal hash.

Let H be the hashing function and m the message:

The message conveyed by the sculpture, as H. W. Janson comments, is that " they knew how to die, barbarians that they were.

In 1896, three Tennessee evangelists ( William Martin, Joe M. Tipton, and Milton McNabb ) with links to Benjamin H. Irwin's Fire-Baptized Holiness Church brought the message of entire sanctification to the western North Carolina countryside when they held a revival in the Schearer Schoolhouse near Camp Creek in Cherokee County.

" Mr. H ", a British agent in Mexico, bribed an employee of the commercial telegraph company for a copy of the message.

The first NA phone line started in 1960, and the first " H & I " group ( H & I and Institutions is a sub-committee of Narcotics Anonymous that carries the message into hospitals and institutions where people cannot get to an outside meeting ) was formed in 1963.

In 1876 W. H. Mallock parodied Pater's message in a satirical novel The New Republic, depicting Pater as a typically effete English aesthete.

In the summer of 1907, Cashwell brought the message of Pentecost to evangelists H. G. Rodgers and M. M. Pinson, who carried the message to Alabama, Florida, Georgia, and Mississippi.

The operation received the support of General Henry H. Arnold, the Chief of the United States Army Air Corps, but planning ended on 28 March, when General Eisenhower sent a message to Marshal Joseph Stalin indicating that the Allied armies would not attempt to capture Berlin, thereby making Eclipse obsolete.

I prefer Mrs. McCullers to Mr. Faulkner because she writes more clearly ; I prefer her to D. H. Lawrence because she has no message.

) " Their message ," writes British scholar Norman H. Snaith, " is recognized by all as marking a considerable advance on all previous ideas ", not least in its " special consideration for the poor and down-trodden ".

In " The Burnt Offering " ( issues # 7-10, originally known as " The Passion of the Cable "), Cable continues with his plan to espouse a philosophy of moderation, and offers invitations to the world's top thinkers, scientists and philosophers to live on Providence ( the recently rebuilt Greymalkin ) in the face of a nervous S. H. I. E. L. D .. Delivering a stark message to the world's leaders, he deliberately sets them all against him by threatening to throw their missiles into the sun.

Later versions of H. 323 introduced the Fast Connect procedure, using the fastStart element of an H. 225. 0 message.

Though he was allowed to leave, a threatening message left in Hill's private bathroom revealed that if he ever desired, infiltrating S. H. I. E. L. D.

The authors -- including Sullivan, Jonathan Rauch, Stephen H. Miller, Paul Varnell, and Norah Vincent -- covered a wide range of topics and did not have one political message.

Of interest is a recent announcement by Du Pont's Polychemicals Dept. of a new methyl methacrylate monomer designated as Monocite H 100, which was developed specifically for production of cast acrylic sheets for the sign and lighting industry.

Af is the work necessary to fill the manometer column from the reference height to H.

The total volume of the system above the reference height is Af, and H can be eliminated to obtain an equation for the total potential energy of the system in terms of H.

The minimum total potential energy is found by taking the derivative with respect to H and equating to zero.

Here, H is the coatings removal force measured parallel to the surface of the substrate and T is the film thickness.

The gyro angular momentum is defined by H.

water is Af and the H stands for hydrogen ; ;

An Arrhenius acid is a substance that increases the concentration of the hydronium ion, H < sub > 3 </ sub > O < sup >+</ sup >, when dissolved in water.

The species that gains the electron pair is the Lewis acid ; for example, the oxygen atom in H < sub > 3 </ sub > O < sup >+</ sup > gains a pair of electrons when one of the H — O bonds is broken and the electrons shared in the bond become localized on oxygen.

The Brønsted-Lowry definition is the most widely used definition ; unless otherwise specified acid-base reactions are assumed to involve the transfer of a proton ( H < sup >+</ sup >) from an acid to a base.

Reactions of acids are often generalized in the form HA H < sup >+</ sup > + A < sup >−</ sup >, where HA represents the acid and A < sup >−</ sup > is the conjugate base.

The numerical value of K < sub > a </ sub > is equal to the concentration of the products divided by the concentration of the reactants, where the reactant is the acid ( HA ) and the products are the conjugate base and H < sup >+</ sup >.

In the modern IUPAC nomenclature, the alkali metals comprise the group 1 elements, excluding hydrogen ( H ), which is nominally a group 1 element but not normally considered to be an alkali metal as it rarely exhibits behaviour comparable to that of the alkali metals.

Abdul Alhazred is a fictional character created by American horror writer H. P. Lovecraft.

An important class of alcohols are the simple acyclic alcohols, the general formula for which is C < sub > n </ sub > H < sub > 2n + 1 </ sub > OH.

Of those, ethanol ( C < sub > 2 </ sub > H < sub > 5 </ sub > OH ) is the type of alcohol found in alcoholic beverages, and in common speech the word alcohol refers specifically to ethanol.

According to Steven H Silver, alternate history requires three things: 1 ) the story must have a point of divergence from the history of our world prior to the time at which the author is writing, 2 ) a change that would alter history as it is known, and 3 ) an examination of the ramifications of that change.

They are known as 2 -, alpha -, or α-amino acids ( generic formula H < sub > 2 </ sub > NCHRCOOH in most cases < ref > Proline is an exception to this general formula.
