Which Generation Is Considered The Last Key Generation

The generation born from 2000 to 2020, disingenuously labeled 'Generation Z', may be the last generation, generational experts are warning.

Lost Generation, a group of American writers who came of age during World War I and established their literary reputations in the 1920s. The term is also used more generally to refer to the post-World War I generation. Learn more about the Lost Generation in this article. Generation X is a so-called lost generation born between 1961 and 1981. We are stuck in the middle between two larger and more boisterous and beloved generations, Millennials and Baby Boomers.

'There are no letters in the English language after Z,' an expert generator explained.

'The Chinese, however, are set until the year of the pig, 34520. In America, though, we'll either have to add a letter after Z, or stop having kids.' The former possibility is not considered likely, as an amendment to the dictionary would require a 2/3 quorum vote of the Intercontinental Congress followed by ratification by at least ¾ of the English speaking states. The latter possibility may become more appealing as college tuition rates continue to rise. The problem in English has been labeled the 'Y2Z Problem'.

'It was just cool to put an 'X' after everything. We had no idea it was going to lead to the extinction of the human race!'

The US government has responded to the upcoming crises in the usual way, by blaming Canada. Canadian author Douglas Coupland was largely responsible for popularizing the alphabetical listing of generations with his book 'Generation X: Tales for an Accelerated Culture'.

'My goal in picking a letter near the end of the alphabet was to accelerate the culture,' Coupland explained in his defense, 'During the Carter administration, most people were convinced the world was going to end in thirty years anyway. Plus, it was just cool to put an 'X' after everything. We had no idea it was going to lead to the extinction of the human race!'

Previously, generations were frequently named after wars in which they had fought. However, the US has not been belligerent enough in recent years to keep the post-war generations going. Use of the present war as a generational naming tool has posed some linguistic difficulties, as 'Post-Enduring Freedom Generation' and 'Post AfghanIraqIranistan Generation' have both proved too much of a mouthful for the members of these generations, whose average age is 2 years old. Proposals to name the current generation after other cataclysmic events of our time, such as the 'Post Britney Spears Generation' or the 'Post 2007 Patriots Generation', have not garnered widespread support. 'Generation ZZZ' has been proposed, but sounds like a tired old solution. Finally, recycling back to the letter 'A' is expected to create an enormous generation gap.

Historians have noted that 'Z' is often an ominous letter in history. 'The Dutch named the islands off the east coast of Australia 'New Zeeland' because they did not expect any more to be discovered,' a historian explained, 'and look what happened to them!' The Netherlands have in fact lost much of their relevance in the modern world, being primarily known for chocolate and uncles.

The generational name generating problem has become more acute in recent years. 'The world is getting smaller, and generations are getting shorter,' the historian continued, 'The 'back in the day' generation lasted for, like, 10,000 years. Now a generation is only good for about 20!'

However, the lack of any progress on the Y2Z problem is not terribly surprising, given that it is 2008 and people still haven't decided what to call the decade that came after 'the nineties'. Tentatively, 'the tenties' has been proposed, while the next decade will be 'the twentysomethings'. At the glacial pace Congress has moved to address this problem, however, it may end up being decided by historians or geologists.

'Most people think it's the first decade of the last millennium,' President Bush explained when confronted with the issue by curious elementary school students.

'But it's actually the last decade of the first millennium, because Christ was born in 1 AD (that's 'After Death'), 1 year after his death.'

'It's all very complicated,' he added after some reflection.

Other politicians have proposed other solutions.

'Given the way this country's going, I say we just start labeling them 'degenerations',' Ross Perot yelled over the giant sucking sound of Americans retiring to Mexico.

Generation

Key generation is the process of generating keys in cryptography. A key is used to encrypt and decrypt whatever data is being encrypted/decrypted.

A device or program used to generate keys is called a key generator or keygen.

Generation in cryptography[edit]

Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA). Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can decrypt this data.

Since public-key algorithms tend to be much slower than symmetric-key algorithms, modern systems such as TLS and SSH use a combination of the two: one party receives the other's public key, and encrypts a small piece of data (either a symmetric key or some data used to generate it). The remainder of the conversation uses a (typically faster) symmetric-key algorithm for encryption.

Computer cryptography uses integers for keys. In some cases keys are randomly generated using a random number generator (RNG) or pseudorandom number generator (PRNG). A PRNG is a computeralgorithm that produces data that appears random under analysis. PRNGs that use system entropy to seed data generally produce better results, since this makes the initial conditions of the PRNG much more difficult for an attacker to guess. Another way to generate randomness is to utilize information outside the system. veracrypt (a disk encryption software) utilizes user mouse movements to generate unique seeds, in which users are encouraged to move their mouse sporadically. In other situations, the key is derived deterministically using a passphrase and a key derivation function.

Many modern protocols are designed to have forward secrecy, which requires generating a fresh new shared key for each session.

Classic cryptosystems invariably generate two identical keys at one end of the communication link and somehow transport one of the keys to the other end of the link.However, it simplifies key management to use Diffie–Hellman key exchange instead.

The simplest method to read encrypted data without actually decrypting it is a brute-force attack—simply attempting every number, up to the maximum length of the key. Therefore, it is important to use a sufficiently long key length; longer keys take exponentially longer to attack, rendering a brute-force attack impractical. Currently, key lengths of 128 bits (for symmetric key algorithms) and 2048 bits (for public-key algorithms) are common.

Generation in physical layer[edit]

Wireless channels[edit]

A wireless channel is characterized by its two end users. By transmitting pilot signals, these two users can estimate the channel between them and use the channel information to generate a key which is secret only to them.[1] The common secret key for a group of users can be generated based on the channel of each pair of users.[2]

Optical fiber[edit]

A key can also be generated by exploiting the phase fluctuation in a fiber link.[clarification needed]

See also[edit]

  • Distributed key generation: For some protocols, no party should be in the sole possession of the secret key. Rather, during distributed key generation, every party obtains a share of the key. A threshold of the participating parties need to cooperate to achieve a cryptographic task, such as decrypting a message.
