Advantages and Disadvantages of Symmetric and Asymmetric Key Encryption Methods
Methods of encrypting messages include the: - Symmetric Key Encryption and - Asymmetric or Public Key Encryption methods. While each system has its proponents and opponents, both methods have pros and cons which are outlined below: Symmetric Key Encryption Symmetric key encryption is also known as shared-key, single-key, secret-key, and private-key or one-key encryption. In this type of message encryption, both sender and receiver share the same key which is used to both encrypt and decrypt messages. Sender and receiver only have to specify the shared key in the beginning and then they can begin to encrypt and decrypt messages between them using that key. Examples include AES (Advanced Encryption Standard) and TripleDES (Data Encryption Standard). Advantages - Simple: This type of encryption is easy to carry out. All users have to do is specify and share the secret key and then begin to encrypt and decrypt messages. - Encrypt and decrypt your own fi...
