- In cryptography,
key size or
key length refers to the
number of bits in a
key used by a
cryptographic algorithm (such as a cipher).
Key length defines the...
-
algorithms accept two inputs: an
input block of
size n bits and a
key of
size k bits; and both
yield an n-bit
output block. The
decryption algorithm D is defined...
- Galois/Counter Mode (GCM) is a mode of
operation for symmetric-
key cryptographic block ciphers which is
widely adopted for its performance. GCM throughput...
- 128-bit file system. 128 bits is a
common key size for
