Some signals carry encryption and specify use conditions ( such as " may not be recorded " or " may not be viewed on displays larger than 1 m in diagonal measure ") backed up with the force of law under the WIPO Copyright Treaty and national legislation implementing it, such as the U. S. Digital Millennium Copyright Act.

Some consider emoticons and ASCII art, like smiley faces, to be leet, while others maintain that leet consists of only symbolic word encryption.

Some special and specific algorithms have been developed to aid in attacking some public key encryption algorithms-both RSA and ElGamal encryption have known attacks that are much faster than the brute-force approach.

Some modern scramblers are actually encryption devices, the name remaining due to the similarities in use, as opposed to internal operation.

Some are no longer relevant given the ability of computers to perform complex encryption, but his second axiom, now known as Kerckhoffs's principle, is still critically important.

( Some encryption algorithms, known as nonmalleable ones, prevent this, but others do not.

Some secure cryptoprocessors contain dual processor cores and generate inaccessible encryption keys when needed so that even if the circuitry is reverse engineered, it will not reveal any keys that are necessary to securely decrypt software booted from encrypted flash memory or communicated between cores.

Some phones include a special monitor mode ( activated with secret codes or special software ) which displays GSM operating parameters such as encryption while a call is being made.

Some virtual networks may not use encryption to protect the data contents.

Some modern modes of operation combine encryption and authentication in an efficient way, and are known as authenticated encryption modes.

Some of the methods of protecting e-business security and keeping information secure include physical security measures as well as data storage, data transmission, anti-virus software, firewalls, and encryption to list a few .< ref name =" canada "> Industry Canada | Industrie Canada.

Some protocols like FTP and Telnet transfer data and passwords in clear text, without encryption, and network scanners can see this data.

Some web servers will not communicate with a client unless it has a 128-bit encryption capability installed on it.

Some basic information about the MIFARE Classic or MIFARE DESFire chip can be read by any ISO / IEC 14443 type A compatible reader, but Oyster-specific information cannot be read without access to the encryption used for the Oyster system.

; Secret system: Some encryption systems will claim to rely on a secret algorithm, technique, or device ; this is categorized as security through obscurity.

Some of the newer pastebins provide features for comparing two or more pastes, synchronous notifications through IRC or XMPP, paste histories, encryption, password protection, and virtual subdomains.

Some encryption systems for which CAMs are available are Logiways, Nagravision, Viaccess, Mediaguard, Irdeto, KeyFly, Verimatrix, Cryptoworks, Mascom, Safeview, Diablo CAM and Conax.

* Some servers require passwords to be stored using reversible encryption.

Some also provide plausible deniability with deniable encryption techniques.

Some examples of file encryption software are GNU Privacy Guard and PGP ).

Some disk encryption systems offer two levels of Plausible Deniability, which might be useful in case a user is required to reveal the password of an encrypted volume.

Some disk encryption software allows encrypted volumes to be resized.

Some new reservoirs for hydroelectric schemes have been given names faithful to the names for natural bodies of water-for example: the Loch Sloy scheme, and Lochs Laggan and Treig ( which form part of the Lochaber hydroelectric scheme near Fort William ).

Some pulse modulation schemes also allow the narrowband analog signal to be transferred as a digital signal ( i. e. as a quantized discrete-time signal ) with a fixed bit rate, which can be transferred over an underlying digital transmission system, for example some line code.

Some rhyming schemes have become associated with a specific language, culture or period, while other rhyming schemes have achieved use across languages, cultures or time periods.

Some forms of poetry carry a consistent and well-defined rhyming scheme, such as the chant royal or the rubaiyat, while other poetic forms have variable rhyme schemes.

Some types of more complicated rhyming schemes have developed names of their own, separate from the " a-b-c " convention, such as the ottava rima and terza rima.

Some piano makers developed schemes to enhance the tone of each note.

Some piano makers developed schemes to enhance the tone of each note.

Some schemes are based on the discretion of an official, such as a social worker.

Some of his schemes, while not resulting in an escape, do lead to the dismissal of an incumbent Number Two on two occasions.

Some schemes that require authentication allow a username, and perhaps a password too, to be embedded in the URL, for example < tt >< nowiki > ftp :// asmith @ ftp. example. org </ nowiki ></ tt >.

Some schemes have " rules " agreed to by the players but not enforced by the game itself.

* Bit order: Some schemes view the low-order bit of each byte as " first ", which then during polynomial division means " leftmost ", which is contrary to our customary understanding of " low-order ".

Some transmission schemes such as frequency modulation use even more bandwidth.

Some of these are get-rich-quick schemes, though many others affect the financial security of the Duke farm, which Hogg has long wanted to acquire for nefarious reasons.

Some would travel from state to state peddling schemes of administrative or military reform.

Some countries have ruled that matrix schemes are illegal on that basis.

The network marketing or multi-level marketing ( abbreviated MLM ) business has become associated with pyramid schemes as " Some schemes may purport to sell a product, but they often simply use the product to hide their pyramid structure.

Some are pyramid schemes.

Some believe MLMs in general are nothing more than legalized pyramid schemes.

Some inkjet manufacturers have tried to prevent cartridges being refilled using various schemes including fitting smart chips to the cartridges that can detect when the cartridge has run out of ink and prevent the operation of a refilled cartridge.

Some progress was also made increasing the pay of NHS manual workers through incentive schemes.

Some signaling schemes do not use electrical wires.
