攻击DES 的主要形式被称为蛮力的或彻底密钥搜索,即重复尝试各种密钥直到有一个符合为止。如果 DES 使用 56 位的密钥,则可能的密钥数量是 2 的 56 次方个。随着计算机系统能力的不断发展,DES 的安全性比它刚出现时会弱得多,然而从非关键性质的实际出发,仍可以认为它是
AES is more secure than the DES cipher and is the de facto world standard. DES can be broken easily as it has known vulnerabilities. 3DES(Triple DES) is a variation of DES which is secure than the usual DES. The rounds in AES are: Byte Substitution, Shift Row, Mix Column and Key Ad...
a把梯子升一点 Rises one the ladder[translate] arespectively, the AES scheme and the Triple-DES scheme we notice a similarity which reflects the property of confusion that respects the proposed algorithm and which is a criterion of good design in cryptography [13].[translate]...
In this paper, we adopted three cryptographic algorithms i.e., AES, DES, RSA for selecting the best algorithm for different types of inputs. Graphical representation of three algorithms decides that which algorithm is best suited according to their encryption time to encrypt the audio, video, ...
AES is considered resistant to all attacks, except brute force. Elliptic Curve Cryptography (ECC)—the algorithm used as part of the SSL/TLS protocol which encrypts communication between websites and their visitors. It provides better security with shorter key lengths; a 256 bit ECC key provides...
We show that the proposed CA-based S-boxes have cryptographic properties comparable to or better than classical S-box tables. The interesting feature of the proposed S-boxes is a dynamic flexible structure fully functionally realized by CA, while the classical DES S-boxes are represented by ...

aThe modification concerns the two Boxes, P-Box and S-Box, which composed the original cryptosystem. Compared with classical encryption schemes, AES and Triple-DES, the new version of the cipher shows a better performances in rapidity, in confusion and in the key sensitivity. modifi正离子...
