a modified aes based algorithm for image encryption

Abstract

Security in transmission storage of digital images has its importance in today's image communications and confidential video conferencing. Due to the increasing use of images in industrial process, it is essential to protect the confidential image data from unauthorized access. Advanced Encryption Standard (AES) is a well known block cipher that has several advantages in data encryption. However, it is not suitable for real-time applications. In this paper, we analyze and present a ....etc

In cryptography the only need of high importance is
security of data.Few ways to achieve it is through public
key cryptography(PKC),secret key cryptography(SKC) and
using hash functions. Generic PKC employs two keys that
are mathematically related although knowledge of one key
does not allow someone to easily determine the other key.
One key is used to encrypt the plaintext and the other key is
used to decrypt the ciphertext(encrypted data). Because a
pair of keys are required, this approach is also called
asymmetric cryptography. T ....etc

Abstract Engine anti-theft system is not only flexible and
convenient but also high-performance, high-efficient and highsecurity.
Based on the identity authentication principle of engine
anti-theft system, with the AES encryption algorithm theory, this
paper proposes the AES encryption methods and steps which are
appropriate for the identity authentication of engine anti-theft
system. It also designs the experimental program and obtains
good results.

Dijkstra's algorithm is called the single-source shortest path. It is also known as
the single source shortest path problem. It computes length of the shortest
path from the source to each of the remaining vertices in the graph.
The single source shortest path problem can be described as follows:
Let G= {V, E} be a directed weighted graph with V having the set of vertices.
The special vertex s in V, where s is the source and let for any edge e in E,
EdgeCost(e) be the length of edge e. All the weights in the graph should be
non-negative. ....etc
