IMPRACTICALITY [3 records]

Record 1 2019-11-26

English

Subject field(s)
  • Encryption and Decryption
  • IT Security
DEF

The process by which a key is created by an algorithm.

CONT

The only cipher that cryptologists have ever proved to be perfectly secure for key generation is the one-time pad(OTP), in which the key is as long as the message itself. But OTPs are rarely used because of their impracticality.

OBS

The most sensitive operation in cryptography.

OBS

key generation: designation and definition officially approved by the Security Terminology Committee (STC).

French

Domaine(s)
  • Chiffrage et déchiffrage
  • Sécurité des TI
DEF

Processus par lequel une clé est créée au moyen d'un algorithme.

OBS

L'étape la plus délicate en cryptographie.

Record 2 2005-03-31

English

Subject field(s)
  • Electrical Engineering
CONT

In spite of its advantages, the process of oxidizing from the upper surface to form a passive isolation region suffers from inherent limitations associated with the oxide growth process. The conversion of exposed silicon to oxide to a given depth below an exposed silicon surface requires the growth of approximately twice that amount of oxide above the surface. For thicknesses beyond 20, 000 angstroms of oxide, oxide growth slows to the point of impracticality and thus the oxide isolation approach is limited to semiconductor devices formed in epitaxial layers from one and a half microns to 2 microns thick.

CONT

Compressed magnesium oxide isolation.

French

Domaine(s)
  • Électrotechnique
CONT

Malgré l'arrivée de nouvelles techniques comme l'isolation par oxyde ou l'isolation totale par tranchée, l'isolation par jonction reste la plus utilisée grâce à la simplicité de son procédé technologique et à son très bon rendement de fabrication.

CONT

Isolation par oxyde de magnésium comprimé.
