Cryptography: Multiple Signature Generation for Group Communication

Multiple signature [10] generation is defined as the multi signature process for providing better and strong security from strong security from various attacks i.e. active attacks and passive attacks. Multisignature is generally based on DKMI protocol (distributed key management infrastructure). MultiSignature is a simple scheme for sending various messages in a group. The main reason of this research paper is introduce this efficient and more secure multiple signature schemes. Our project provides brief information regarding DES and DSA Algorithms along with spam filter features and cryptography, basically DES algorithm is part of cryptography and which is implementing on sending and receiving messages and used for encryption and decryption for providing confidentiality and avoid from further data alteration. The main concept of DES algorithm is providing secure communication over a non-secure network channel. DSA algorithm is used to create a digital signature for proving authentication and non-repudiation features and another module in this project is socket programming which enables to send different format of files in group i.e. images, video, audio etc.
