Comparative Study of Database Security In Cloud Computing Using AES and DES Encryption Algorithms

Journal of Information Security and Cybercrimes Research, 2019
Security is consider as one of the largest part important aspects in daily computing. The security is important in cloud computing especially for data save in cloud because it have sensitivity and import data as well many user can access to same data ...

On the Design of Perceptual MPEG-Video Encryption Algorithms [PDF]

, 2006
In this paper, some existing perceptual encryption algorithms of MPEG videos are reviewed and some problems, especially security defects of two recently proposed MPEG-video perceptual encryption schemes, are pointed out.

Cryptanalysis of a computer cryptography scheme based on a filter bank [PDF]

, 2007
This paper analyzes the security of a recently-proposed signal encryption scheme based on a filter bank. A very critical weakness of this new signal encryption procedure is exploited in order to successfully recover the associated secret key.Comment: 6 ...

On the Optimality of Quantum Encryption Schemes

, 2005
It is well known that n bits of entropy are necessary and sufficient to perfectly encrypt n bits (one-time pad). Even if we allow the encryption to be approximate, the amount of entropy needed doesn't asymptotically change.

Attribute‐based encryption implies identity‐based encryption [PDF]

IET Information Security, 2017
In this study, the author formally proves that designing attribute‐based encryption schemes cannot be easier than designing identity‐based encryption schemes. In more detail, they show how an attribute‐based encryption scheme which admits, at least, and policies can be combined with a ...

Uncloneable encryption

Quantum Information and Computation, 2003
Quantum states cannot be cloned. I show how to extend this property to classical messages encoded using quantum states, a task I call ``uncloneable encryption.'' An uncloneable encryption scheme has the property that an eavesdropper Eve not only cannot read the encrypted message, but she cannot copy it down for later decoding.
