Spam Security Through Encryption Of E-Mails

Jul 19th 2015 at 11:38 PM

An email encryption provider offers a wide range of features to their clients as spam control and filter, choice of IMAP instead of download POP protocol, and data encryption. Besides this, you can also depend upon them for protection against phishing, virus and spam, HTTP and non-HTTP coding. An effective encryption of your e-mails can prove to be a strong safeguard against spam messages that make life difficult for businesses and make the mailbox overflow with junk.

Many people choose such service providers especially to help them get rid of these unwanted bombarding of messages. In this regard, you should know that encryption alone won't be able to help you in your fight against spam as it can worsen the results instead. This happens because of the way cryptographic modern protocols utilize the encryption of the public key. So if a spam filter is unable to do its job properly as it is unable to decrypt the messages or examine associated content, it will allow even dangerous messages to get past.

Because of this reason, service providers combine encryption with technology authentication that relates closely. Good news for you is that major encryption public key solutions support authentication and encryption. In this kind of encryption, all users have access to both private and public keys created together. You will share your public key of encrypted email with people you would like to exchange the secure mails. In this kind of arrangement, senders will use the public key of the recipient for data encryption.

However decrypting this data will be possible only with the private key of the recipient. Public keys as per definition available to the public, as such, spammers may use this for spam encryption that they will then send to the owner of the key. There are hardly any spam blockers available presently that can decrypt such messages so scanning for presence of malicious attachment almost becomes impossible. Use of private key is involved in the authentication process that creates digital signature to attach with outgoing e-mail.

Such signatures remain unique for messages that led to their creation and as such, it is not possible to reuse them further. Recipients can use appropriate tools to verify the sending of the messages to trusted, known correspondents. Major server solutions and client e-mail programs support authentication and encryption with two main protocols available. These are:

  1. S/Mime with Outlook support
  2. PGP and GPG its derivative

E-mail clients after undergoing configuration for use of authentication and encryption tend to hide many complexities associated with e-mail exchange. The key source remains the major difference between the two types of protocols along with associated trust levels. An authenticating agency will grant the S/Mime keys while GPG and PGP is end user generated. Authentication and encryption together add to the e-mail interchange processing requirements significantly. Only a handful of organizations require encryption of every generated e-mail. The advice to the businesses would be to encrypt only confidential messages and secure them with digital signatures.

Do it the easy way. Leave out guesswork from encryption by choosing secure email service available only at http://zixmailencryption.com/.
