RC6like

RC6like is a symmetric key block cipher that is a variant of the RC6 cipher. It was developed by RSA Laboratories and is part of the RC6 family of ciphers, which are known for their simplicity and efficiency. RC6like is designed to be a lightweight and fast cipher, making it suitable for applications where performance is a critical factor.

The structure of RC6like is similar to that of RC6, with a focus on simplicity and efficiency. It uses a simple round function that consists of data-dependent rotations, modular addition, and XOR operations. The key schedule of RC6like is also similar to that of RC6, generating a sequence of subkeys from the original key.

One of the key features of RC6like is its use of data-dependent rotations, which help to increase the diffusion of the plaintext throughout the cipher. This makes RC6like resistant to certain types of cryptanalytic attacks, such as differential and linear cryptanalysis.

RC6like is typically used in software implementations, where its simplicity and efficiency can be fully utilized. It is not as widely used as some other ciphers, such as AES, but it remains an important cipher in the field of cryptography due to its simplicity and efficiency. Its design principles have also influenced the development of other ciphers, making it a valuable contribution to the field of cryptographic research.
