Finally, the ciphertext
in Through the Looking Glass is the story itself.
This bound was especially worrisome for the Black and Rogaway construction because running at three rounds, 10,000 ciphertext
/plaintext pairs would give an attack that would leak information about other ciphertexts
The "Texts" column indicates the information required to effect the attack, specifically, the number of plaintext blocks and corresponding ciphertext
blocks encrypted under the secret key.
A robust algorithm, such as DES, processes the plaintext in a way that makes it impossible to find any correlation between ciphertext
Adopted as a data security standard by the United States government in 1977, the DES enciphers a 64-bit block of plaintext into a 64-bit block of ciphertext
under the control of a 56-bit key.
In case (1), various access conditions will be set in detail for each encrypted data in a cloud computing database, and a user will be able to decrypt and access the data by using the decryption key when the attributes of the decryption key satisfy the pre-set predicates in the ciphertext
Let c be the ciphertext
to be decrypted, where [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]
Delerablee's scheme achieves IND-sID-CPA security, and the ciphertext
length and private key size are constant.
Then, each super-peer will forward the ciphertext
corresponding to the ratings profile over the entire group to the PRS.
Keys are the fundamental essential element in generating modern ciphertext
Following this procedure, the ciphertext
is transmitted over the Internet to the user's mail server.
is used by the decryption process to produce the original plaintext.
