Mahesh P, Basappa B. Kodada, Shivakumar K. M . Spam Control Mechanism using Identity based Message Admission. International Journal of Computer Applications. 74, 3 ( July 2013), 24-31. DOI=10.5120/12865-9696
Spammers have a tremendous financial incentive to compromise user Email accounts. Many approaches to curb spam have been developed. In the traditional DKIM signature approach no Certificate Authority is used. Survey tells that most of the DNS are exploited to DNS cache poisoning attack. Further smaller keys are exposed to Wiener attack. Also DKIM does not verify the author and does not provide security after signature generation/verification. An attacker can be able to trick the recipient by masquerading as a legitimate sender and insert malicious information and send as spam Mails to other recipients. Therefore this paper addresses the issues by allowing sender to indicate that their emails are signed and encrypted using ID based mediated RSAA technique based on user identity. This system use Certificate Authority and a key Mediator in its architecture. During decryption the Key mediator does partial decryption and the recipient does full decryption of message. If original message is recovered and verified the sender message is accepted else rejected or blocked as spam message.
