How PGP works in securing email correspondences on Blackberry devices

Email messages sent between Blackberry devices can be encrypted using PGP encryption. But how does this encryption encrypt the messages such that the intended recipients are the only parties that can decrypt the messages? Basically, PGP encryption for Blackberry devices utilizes qualified public key system. This public key system is used to encrypt all email messages to and fro Blackberry devices. When two Blackberry devices are pgp encrypted, each device will have an encryption key. This encryption key is private and is only known to the user of the device. Even though a company may be offering Blackberry PGP encryption services, the company will not know the private encryption key.

The user will also have a public encryption key, which will be known to other Blackberry users so that they can communicate with them effectively or authenticate the messages they send between each other. Both the private and public encryption keys work in tandem in various ways. First, a sender compiles an email and then hits the Send button. This email message is then compressed. Since the sender’s device is PGP encrypted, the encryption creates a Session Key at random that can only be used once to encrypt the already compressed message. This encryption is done on the sender’s device.

The Session Key is very important because it will be needed by the recipient to decrypt the email message. After creating the Session Key, the key will be encrypted using the public key on the recipient’s Blackberry device and will be specifically trussed on the same device. For the recipient to decrypt the message, this will only happen if the recipient is using the private key on the same encrypted pgp blackberry device. Both the encrypted Session Key and the email are then sent to the intended recipient.

In case the email message is intercepted in any way, the message will be useless to the interceptor since both the Session Key and the email are encrypted using PGP encryption. For the intercepted message be decrypted and read, a private key is needed and this key can only be found on the recipient’s Blackberry device. Upon receiving the email, the PGP encryption algorithm decrypts the sender’s Session Key automatically using the private key on the recipient’s device. It is worth mentioning that it is only the recipient that knows the private key.

This means that even the company that offers the PGP blackberry encryption service does not know the private key. The private key is only tied to one Blackberry device. Therefore, no other device or person has the capacity of decrypting the Session Key. PGP encryption is generally powerful and even if a third party intercepts and tries to decrypt the message, it will take a long time or never to decrypt the message.
