In this paper, we propose a cryptosystem (encrypting/decryption) for XML data using Vigenere cipher algorithm and EL Gamal cryptosystem. Such a system is designed to achieve some of security aspects such as conﬁdentiality, authentication, integrity, and non-repudiation. We used XML data as an experimental work. Since, we have used Vigenere cipher which is not monoalphabetic, then the number of possible keywords of length m in a Vigenere Cipher is 26 m, so even for relatively small values of m, an exhaustive key search would require a long time.
