key length

The number of bits available for the longest keys in a cryptographic implementation. For example, the key length of a particular Diffie-Hellman/DSS PGP key can be anywhere from 1024 bits to 4096 bits. See key space and key fingerprint.

However, the large key size of the original McEliece makes it difficult to be applied in practice on embedded devices with limited resources [4].
This process will reduce the public key size from the size of [tau] to the size of 2[square root of ([tau])] integers of [gamma] bits.
ECC was proposed in 1985, by Miller [25] and Koblitz [26], When comparing ECC with other public key cryptosystems, it was found that ECC-based public key cryptosystem has many advantages such as low computation cost, smaller key size, low storage space cost etc.
We make the comparison in the aspect of the public/private key size, reencryption key size, level 1/level 2 ciphertext size, reencryption key generation cost, reencryption cost, and security model.
To help end users achieve these objectives, Goodyear has added a key size, 20.5R25, to the AS-3A.
The sorter's "accept" stream leads to a Key size grader with grading screens that separate the good fruit into three size grades.
The drawback of KPS is that the user key size is combinatorial large in the total number of users (if the system is unconditionally secure).
Here, addressed attacks are as follows: key size being 10195, histogram analysis, correlation analysis, and differential analysis.
To overcome memory and computation overhead, the proposed scheme uses 32-bit key size which has lesser overhead from traditional cryptographic techniques like DES, AES, 3DES, and Blowfish.
The presented stegnography technique offered a very large key size, to extract covered information, in addition to basic purpose of stegnography.
