There are many cryptography techniques that are used to encrypt and decrypt data that are transferred over a network. There are two basic types of cryptography :Symmetric Key and Asymmetric key. This paper describes various encryption techniques(Substitution and transposition) with their limitations ....
Instead of relying on the techniques of substitution and transposition, which symmetric key cryptography uses, asymmetric algorithms rely on the use of massively large integer mathematics problems. Many of these problems are simple to do in one direction but difficult to do in the opposite direction...
aEncryption methods have historically been divided into two categories: substitution ciphers and transposition ciphers. We will now deal with each of these briefly as background information for modern cryptography. 加密方法历史上被划分了成二个类别: 替换密码和交叉点暗号。 我们简要地现在将涉及每一个这些...

Cipher text:When any plain text is codified using a suitable scheme and the resulting message is a cipher text. There are two ways by which we can primarily change plain text to cipher text bySubstitutionandTransposition. Caesar Cipher

The key is private, and the encryption and decryption algorithms are made public because it is impossible to decrypt the cipher text without the key. Two types of operation are used to transform plaintext to ciphertext: substitution and transposition. Both of these techniques ensure that the oper...
