Over a relatively short period of time, usually about four to twelve weeks, the worker must be able to shift the focus, back and forth, between immediate external stressful exigencies ( `` precipitating stress '' ) and the key, emotionally relevant issues ( `` underlying problem '' ) which are, often in a dramatic preconscious breakthrough, reactivated by the crisis situation, and hence once again amenable to resolution.

I submit that this is the key problem of international relations, that it always has been, that it always will be.

Symmetric-key ciphers are suitable for bulk encryption using shared keys, and public-key encryption using digital certificates can provide a practical solution for the problem of securely communicating when no key is shared in advance.

A key distinction between analysis of algorithms and computational complexity theory is that the former is devoted to analyzing the amount of resources needed by a particular algorithm to solve a problem, whereas the latter asks a more general question about all possible algorithms that could be used to solve the same problem.

The government faced the problem that a key piece of evidence – Lindh's confession – might be excluded from evidence as having been forced under duress ( i. e. torture ).

This inability to distinguish distributions with a comb-like shape from continuous distributions is a key problem with all statistics based on a variant of the K-S test.

John Harrison, a self-educated English clockmaker then invented the marine chronometer, a key piece in solving the problem of accurately establishing longitude at sea, thus revolutionising and extending the possibility of safe long distance sea travel.

The inability to pin an idea or cultural feature to quantifiable key units is widely acknowledged as a problem for memetics.

The problem with this system, is that it provides only a crude binary on / off signal for each key.

The problem of correctly identifying a public key as belonging to a particular user is not unique to PGP.

All public key / private key cryptosystems have the same problem, if in slightly different guise, and no fully satisfactory solution is known.

The Diffie – Hellman key exchange relies on the fact that there are efficient algorithms for modular exponentiation, while the reverse operation the discrete logarithm is thought to be a hard problem.

A central problem with the use of public-key cryptography is confidence ( ideally, proof ) that a particular public key is correct, and belongs to the person or entity claimed ( i. e. is " authentic "), and has not been tampered with, or replaced by, a malicious third party ( a " man-in-the-middle ").

The usual approach to this problem is to use a public-key infrastructure ( PKI ), in which one or more third parties-known as certificate authorities-certify ownership of key pairs.

To date, no fully satisfactory solution to this " public key authentication problem " has been found.

However, revoking a key now requires both Alice and Bob to be available, and this creates a problem of reliability.

The design and strength of all key lengths of the AES algorithm ( i. e., 128, 192 and 256 ) are sufficient to protect classified information up to the SECRET level.

Several key factors influenced the design of the 7800.

After moving to Sarov in 1950, Sakharov played a key role in the development of the first megaton-range Soviet hydrogen bomb using a design known as " Sakharov's Third Idea " in Russia and the Teller-Ulam design in the United States.

Notable features of the design include key-dependent S-boxes and a highly complex key schedule.

Controversies arose out of classified design elements, a relatively short key length of the symmetric-key block cipher design, and the involvement of the NSA, nourishing suspicions about a backdoor.

Some formal design methods and programming languages emphasize data structures, rather than algorithms, as the key organizing factor in software design.

A key consideration in the design of transmitters is their power consumption as this is closely related to their signal strength.

He played a key role in the design of the first American flag.

Some trigger locks are integrated into the design of the weapon, requiring no external parts besides the key.

One of the key features of graphic design is that it makes a tool out of appropriate image selection in order to possibly convey meaning.

The International Monetary Fund was one of the key organizations of the international economic system ; its design allowed the system to balance the rebuilding of international capitalism with the maximization of national economic sovereignty and human welfare, also known as embedded liberalism.

A well-known class of IBM PC keyboards is the Model M. Introduced in 1985 and manufactured by IBM, Lexmark and Unicomp, the vast majority of Model M keyboards feature a buckling spring key design and many have fully swappable keycaps.

When a given task is appropriate for a team, task design can play a key role in team effectiveness ( Sundstrom, et al., 2000 ).

The key challenges for SuperJanet4 were the need to increase network capacity and to strengthen the design and management of the Janet network to allow it to meet a similar increase in the size of its userbase.

The design of the HMAC specification was motivated by the existence of attacks on more trivial mechanisms for combining a key with a hash function.

" The KISS principle states that most systems work best if they are kept simple rather than made complex, therefore simplicity should be a key goal in design and unnecessary complexity should be avoided.

Although fitting of keys to replace lost keys to automobiles and homes and the changing of keys for homes and businesses to maintain security are still an important part of locksmithing, locksmiths today are primarily involved in the installation of higher quality lock-sets and the design, implementation and management of keying and key control systems.

A key component of a microkernel is a good IPC system and virtual-memory-manager design that allows implementing page-fault handling and swapping in usermode servers in a safe way.

The DKW Schnellaster, manufactured from 1949 to 1962 was a small monospace ( or one-box ) design featuring its front wheels set forward of the passenger cabin, a short, sloping aerodynamic hood, front-wheel drive, transverse engine, flat load floor throughout with flexible seating and cargo accommodations – the key design ingredients that describe the modern minivan configuration popularized in such notable examples as the Renault Espace and Chrysler Voyager / Caravan minivans.

It is reported that Edson de Castro, who had been a key member of the design team, left to form Data General when his design for a 16-bit successor to the PDP-8 was rejected in favour of the PDP-11 ; the " PDP-X " did not resemble the Data General Nova, although that is a common myth.
