ABSTRACT
Many businesses monitor employee computer files, e-mail, or voice mail. Bulletin board systems, college campus networks, commercial information services, and the Internet are mainly open information systems where hackers can easily tamper with e-mail. A secure e-mail standard allows users to communicate safely between separate or unknown mail platforms. Secure Multipurpose Internet Mail Extension (SMIME) guarantees security end to end using digital signature technology. The SMIME specification was developed to allow interoperability between various e-mail platforms using Rivest-Shamir-Adleman encryption. Businesses are working closely with agencies such as the Internet Engineering Task Force (IETF) to achieve effective security for e-mail on the Internet. Privacy Enhanced Mail (PEM) encrypts e-mail into the Multipurpose Internet Mail Extension, which is the standard for attaching files to an e-mail message. The Internet (PEM) standard is the method of encrypting e-mail recommended by the IETF. The Internet Mail Consortium plans to build consensus on conflicting Internet mail security protocols by holding informative workshops.
