The better solution to offer the necessary protection against the data intruders is cryptography. Cryptography is the one of the main categories of computer security that converts information from its normal form into an unreadable form by using Encryption and Decryption Techniques. The Cryptography ...
The main characteristics that identify and differentiate one encryption algorithm from another are its ability to secure the protected data against attacks and its speed and efficiency in doing so. In this paper we provides a comparison between most common symmetric key cryptography algorithms: DES, ...

RC2 and RC5:Ronald Rivest (RSA Labs), developed these algorithms. They are block encryption algorithms with variable block and key sizes. It is difficult to break if the attacker does not know the original sizes when attempting to decrypt captured data. ...
Two symmetric key encryption algorithms are widely used in networks. These are: • Data Encryption Standard (DES): The DES encryption algorithm is a “block cipher” that encrypts information in blocks of 64 bits (8 bytes). Using a 56-bit key, DES encrypts each block in 16 identical ro...
Outline the difference between symmetric and asymmetric encryption algorithms.相关知识点: 试题来源: 解析 对称加密使用单一密钥进行加密和解密,速度快但密钥分发存在风险;非对称加密使用公钥和私钥配对,安全性更高但计算开销大。 1. **密钥机制**: - 对称加密(如AES、DES)依赖同一密钥进行加密/解密,要求通信双方...
