Posta Elettronica e Sicurezza: una applicazione

Digital signature can be associated with Internet messages in order to guarantee authentication, message integrity and non-repudiation of origin. Verification of incoming digitally signed messages is usually implemented by e-mail clients (receiving agents) implementing this function on behalf of the end-user. However in specific context, where message content is automatically elaborated, signature verification by e-mail client could become a system bottleneck, thus justifying an automatic verification system. In this work we briefly describe our experience in designing and implementing software in order to automate the verification process of signed e-mail. The system has been designed to simplify the registration of Internet domains under the .IT Top Level Domain.
