The Importance Of Privacy

Have you ever heard of Spy-Free or Spy-Proof Emails? Most of people do not know well about the importance of privacy in their email and even they realize its importance, they are not sensitive to it. Now, the world’s best-known email providers Yahoo, and Google put in a great deal of effort to encrypted email system. They will introduce a new secure email system in the near future. However, some experts bring up several problems of encrypted mail. Christopher Soghoian, a security and privacy researcher at the American Civil Liberties Union, said “Yahoo and Google are taking early steps to making the technology easier for normal consumers.” It can be interpreted that few users will adopt the technology immediately. This paper explains what PGP …show more content…
PGP is an abbreviation for “Pretty Good Privacy.” It is a hybrid encryption since PGP is a combination of some best features of both original and public key cryptography. If you encrypt the plaintext using PGP, it firstly compresses the plaintext and by data compression, modem transmission time and disk space are saved. Also, data compression strengthens cryptographic security. Next, Patterns in the plaintext are reduced by compression, by doing so, there will be a significant enhancing resistance to cryptanalysis. Then, PGP creates a ‘session key’, which is a one-time-only secret key which works with a highly secure, fast conventional encryption algorithm to encrypt the plaintext; the result is cipher text. Lastly, “Once the data is encrypted, the session key is then encrypted with the public key. This public key-encrypted session key is transmitted along with the cipher text to the recipient.” ("How PGP works", 1999) To introduce a merit of PGP briefly, the most well-known advantage of PGP is a person’s valuable information is always protected. Others cannot access or view it, and it cannot be stolen over the internet. Thus, a person who deals with critical data must need this technology to prevent spies and …show more content…
Because standard email messages that they normally use can make it possible for someone else to trace their personal information. (Poremba, 2013) For instance, my email which included my banking account and its password can be leaked by hackers. PGP has its advantages and disadvantages; many of the disadvantages to PGP can be overcome through training and some are hardly occured. But for better using, developers of the PGP encryption system should gradually minimize its weak points. This technology will contribute to secure email
