Abstract—The protection of data is the key mechanism for data security. The challenges faced to protect the data explore new algorithms. The evolution of encryption of encryptions in the field of cryptography may provide better security than single encryption routine. In this context, the multi-encryption came in picture. This paper deals the multi-encryption approaches of RC6 and XTEA block ciphers. The result and analysis of these approaches produce the security level and the processing speed.
Index Terms—Multiencryption, RC6, XTEA.
