This key is used by all parties to both encrypt and decrypt messages, so the sender and the receiver both possess a copy of the shared key. Symmetric key cryptography has several weaknesses: Key distribution is a major problem. Symmetric cryptography also known as public key cryptography uses only one key i.e. But using symmetric encryption instead (and a semi-trusted third party). Symmetric encryption. In this article, we will discuss about symmetric key cryptography. Whereas asymmetric cryptography uses a private key and a public key for encryption and decryption process respectively. And Bob can decrypt without knowing Alice's (symmetric) key. The symmetric key algorithms are quite efficient, but the key distribution is difficult to IoT end devices. Taking the example I gave above, sending a secure message to your granny, both of you need to have the same key in order to encrypt and decrypt the messages that you may exchange with each other. Another difference between asymmetric and symmetric encryption is the length of the keys. Symmetric Key Cryptography; Asymmetric Key Cryptography . Symmetric Key Cryptography- In this technique, Both sender and receiver uses a common key to encrypt and decrypt the message. In symmetric encryption, you use the same key for both encryption and decryption of your data or message. Symmetric cryptosystem was recommended for its open algorithm, less calculation, high speed and efficiency. PKC and asymmetric cryptography are two effective ways of providing confidentiality and authentication. However, it also comes with the disadvantages of the "one key" for encryption and decryption, and the perfect security cannot be guaranteed. Symmetric key cryptography can also be called secret key cryptography and private key cryptography. This secret key … The question is: 1- Does Group Ciphers have any other applications in the literature (with references) ? the secret key to encrpt as well as to decrypt. Examples of symmetric key cryptography: AES , … Key distribution under symmetric key encryption requires either (1) that two communicants already share a key, which someone has been distributed to them or (2) the use of a key distribution center. The key distribution requires a secure connection between the key distribution sever and the IoT nodes. Just like asymmetric encryption. They also prove that the Pohlig-Hellman cipher has this property.
