Public-key cryptography Alice uses to encrypt-key that is Cryptography technology can be divieded as Symmetric key distributed publically for transformation of plain text and cryptography (SKC) algorithm and Asymmetric key only the authorized person with dedicated-private can Cryptography (AKC) algorithm. symmetric key algorithms i.e. DES, RC2, RC4, IDEA etc. This paper describes cryptography, various symmetric key algorithms in detail and then proposes a new symmetric key algorithm. Algorithms for both encryption and decryption are provided here. The advantages of this new algorithm over the others are also explained. The symmetric key algorithms are quite efficient, but the key distribution is difficult to IoT end devices. The key distribution requires a secure connection between the key distribution sever and the IoT nodes. PKC and asymmetric cryptography are two effective ways of providing confidentiality and authentication. Despite these drawbacks, however, symmetric-key cryptography does have a place in computer security. As it turns out, symmetric-key algorithms are the simplest, fastest cryptographic algorithms we know of. In a world built on bandwidth, this speed is a necessity. Symmetric-key algorithms also really make a difference in the embedded world. Symmetric Key Cryptography () Introduction Also known as SECRET KEY, SINGLE KEY, PRIVATE KEY Assumption: Sender and Receiver share already a secret key Assumption requires solution to key-distribution problem Symmetric key algorithms also popular for file encryption, then Encrypter = Decrypter WEAK ALGORITHMS Classical substitution andAuthor: Michael Huth.paper describes cryptography, various symmetric key algorithms in detail and then proposes a new symmetric key algorithm. Algorithms for both encryption and . Keywords— Cryptography, Encryption, Decryption, Survey, Symmetric Key Symmetric Encryption algorithms play a primary role in information security. So this. Symmetric, or secret key, encryption is the most commonly used form of cryptography, because the shorter key length increases the speed of execution. 2, Feb Classification of Efficient Symmetric Key Cryptography Algorithms Shivlal Mewada Pradeep Sharma S. S. Gautam Dept. of Computer Science, Dept . share already a secret key. ➢ Assumption requires solution to key-distribution problem. ➢ Symmetric key algorithms also popular for file encryption, then.
