This paper is aimed to evaluate the importance of XML Signature and XML Encryption in Web Service Security. In today's business scenario, organizations are investing huge amount of resources in Web Services. Web Service Transactions are done mainly through plain-text XML formats like SOAP and WSDL, hence hacking into them is not a tedious task. XML Signature and XML Encryption ensure security to XML documents as well as retain the structure of documents, thereby making it easy to implement them. These two methods are evaluated on the parameters of authentication, authorization, integration, confidentiality and non-repudiation.

This review is aimed to evaluate the importance of Symmetric Key Cryptography for Security in Distributed Systems. Businesses around the world as well as research and other such areas rely heavily on distributed systems these days. Hence, security is also a major concern due to the openness of the system. Out of the various available security measures, we, in this paper, concentrate in general on the symmetric key cryptographic technique. We review two widely used and popular symmetric key cryptographic algorithms, viz. DES and AES. These two algorithms are evaluated on the parameters such as key size, block size, number of iterations, etc.
