This paper proposes a Dynamic Symmetric block Cipher for encryption and decryption. It uses varying number of keys in each round with varying key length. Depends on the application the key length can be chosen. To increase the security, it can be enhanced into n number of levels (Rounds). It is a simple algorithm parameterized by the block size, the number of rounds, and key length. These parameters can be adjusted to meet different goals for security and performance.
