Essays on Encryptions

Cryptography can be simple described as “a technique of encoding and decoding messages, so that they cannot be understood by anybody except the sender and the intended recipient” (Godbole & Kahate, 2003). Symmetric and asymmetric encryptions are the two major technologies used by contemporary organizations to secure their data; hence offering particular advantages when compared. In symmetric key cryptography, encryption and decryption are executed using a similar key whereas two different keys are used for the mentioned purposes in asymmetric key cryptography. The encryption/decryption speed in symmetric key cryptography is considerably faster than that in asymmetric key cryptography. In comparison, ...

Response 1

I defer with the reply that Point Tunneling Protocol (PPTP) provides no encryption capability. The reason as to why I defer with the response is because PPTP does allow multiprotocol traffic to be encrypted. It then encapsulates the encryptions in an IP header and then sends them to an IP network . On the other hand, I do agree with the statement provided in regards to L2TP which does use multiple protocols in supplying encryptions to the connection. It is also true that Secure Socket Tunneling Protocol (SSTP) uses Secure Socket Layer (SSL) in providing encryptions. I am in agreement ...

The article ‘‘Foiling the Cracker’’: A Survey of, and Improvements to, Password

Security by Daniel V. Klein was published in 1990. Klein looks into system security and discusses how people can hack passwords. He claims that the issue of security has always been a challenge to most individual accounts as there are people who know how to manipulate such accounts such that they hack them and get vital information about another party. He discusses the various ways in which technology has motivated the interference of system ...
