Illustrate the Encryption and Decryption methods
One of the best method of ensuring security is to change the form of communication. Let the messages be encoded in such a pattern that it becomes almost impossible to decode for others while the actual user should be able to decode with the use of a simple certificate or key. There are three well known implementations of the encryption/decryption methods:
Even though there are a number of other solutions available, the encryption/ decryption methods have remained most popular and economical in comparison with the other methods. Details about each of the security solution have been discussed in detail in the following paragraphs.
Instruction level This is the initial level and the degree of parallelism is uppermost at this level. The fine grain size is used at statement or instruction level as only few
