Organizations use a wide variety of encryption technologies for various purposes

Question

Organizations use a wide variety of encryption technologies for various purposes. A key aspect of security is to apply the correct and necessary levels of encryption and hashing. The type of encryption and hashing needed varies according to the type of organization: government, military, healthcare, academic, business, financial, etc.

For this discussion, address at least two of the following questions.

Why is cryptology important in information security?

What implications would follow from not using cryptological technologies?

Why might vendors propose proprietary encryption methods? Why is this recommendation suspect and what are possible or likely downside risks to adopting a proprietary encryption technology?

What are the benefits of using encryption? What are the negatives or costs associated with using encryption?

Explanation / Answer

Question 1:- Cryptography is basically is a science of encrypt and decrypt data using mathemetics. Cryptography is very essential in information security because using this technique user can secure his /her message using different encryption algorithms like Diffie-Hellman,DES,AES,RSA ,IDEA,3DES and Elliptic Curve Cryptography. Using this algorithm user can make his/her message secure in the format of encrypted message and using security key he/she can decrypt the message as per requirements.

Question 2:- Due to some below mention reasons cryptographic encryption technologies not implemented widely

1. Complexity in the protocol, requirements of computer programming and frequently generated bugs due to complex codes is the main reason of it is not implemented widely

2. Hackers frequently decrypted data using encrypted message using different type of tools

3. Extra cost burden is the another main reason why it is not usefull for industrial purpose
