Encryption

The coding of sensitive information for transfer online or otherwise electronically. One may encrypt data to prevent anyone other than the intended recipient from accessing it. For example, if one buys a product online and enters credit card information into an electronic form, that information is usually encrypted so hackers and potential identity thieves cannot use it for illicit purposes.

encryption

The manipulation of data to prevent accurate interpretation by all but those for whom the data is intended. Financial institutions use encryption to increase the security of data transmitted via the Internet.

Our results in Section 4.2 show that the large ciphertexts lead to a high communication overhead.

SymmetricBlind satisfies perfect leak-freeness against Alice for a single decryption of a maximum of L [less than or equal to] p - 1 ciphertexts.
Besides, DACC requires the data owner to take part in revocation and transmit an updated ciphertext component to every unrevoked user.
If an attacker wants to make replay attack in the same period, then it should modify [r.sub.0] in ciphertext [mathematical expression not reproducible] that is also impossible.
He knows where each ciphertext unit [c.sub.j] begins and ends.
This model can be divided into two types: the known ciphertext model and known background model [12].
Set the ciphertext CT = (C', [C'.sub.1], {[C.sub.i], [[D.sub.i]}.sup.l.sub.i=1], [{[c.sub.i].sup.t-1.sub.i=0] [E.sub.1], [E.sub.2], [[lambda].sub.t], [[lambda].sub.2]).
