Module 6 Assignment Wendy E. Atkinson Saint Leo University Abstract This paper identifies several topics such as the type of protocols and cryptosystems used to complete online financial transactions, the development and implementation of Advanced Encryption Standard (AES), a fire control system in an automated server room, factors considered when converting general office space to a server room, and power systems in server rooms. Research indicates the use of secure hypertext transfer protocols
In this paper there are two main types of cryptography symmetric and asymmetric encryption. Thought time Cryptography has evolved rapidly during world war one and world war two the allies used it to send messages between one the other. Symmetric algorithms encrypt and decrypt with the same key. Main advantages of symmetric algorithms are their security and high speed. Asymmetric algorithms encrypt and decrypt with different keys. Data is encrypted with a public key, and decrypted with a private key
PUBLIC KEY (ASYMMETRIC) ENCRYPTION Asymmetric Encryption is used to protect the data while in movement. Asymmetric Encryption is also known as Public Key Encryption. It uses two related keys, a public key and a private key which is not shared with anyone. This pair of keys are developed by mathematical methods which can be solved in one direction. So anyone can encode a data using the public key but only the user with a private key can decode that specific data. The length of Asymmetric Key Encryption
1. INTRODUCTION Two simple techniques for encrypting information are: symmetric encryption (also called secret key encryption) and asymmetric encryption (also called public key encryption). Symmetric algorithms are faster, but the main problem associated with this algorithm is key distribution. On the other hand, asymmetric encryption eliminates key security problem, but these algorithms take too much time for encryption and decryption. Certain systems use asymmetric encryption for secure key exchange
Symmetric cryptography, also known as secret key cryptography, has been in use for thousands of years in forms ranging from simple substitution ciphers(figures) to more complex developments. Be that as it may, improvements in science and the development of computing power have made it possible to make ciphers(figures) that are effectively unbreakable and secured. Symmetric frameworks are for the most part quick however are powerless so the key used to encrypt must be imparted to whomever needs to
