end to be understood. Fig.1 shows the simple flow of commonly used encryption algorithms. Fig.1 Encryption-Decryption Flow As defined in RFC 2828 [RFC2828], cryptographic system is "a set of cryptographic algorithms together with the key management processes that support use of the algorithms in some application context." This definition defines the whole mechanism that provides the necessary level of security comprised of network protocols and data encryption algorithms. 2.1

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and

Hardware, software and the data that resides in and among computer systems must be protected against security threats that exploit vulnerabilities. Organizations must therefore impose appropriate controls to monitor for, deter and prevent security breaches. Three areas have been considered, in a typical sense, as the basic critical security requirements for data protection: confidentiality is used to assure privacy; principles of integrity assure systems are changed in accordance with authorized

There are two types of cryptography. Secret key cryptography is also known as symmetric key cryptography. With this type of cryptography, both the sender and the receiver know the same secret code, called the key. Messages are encrypted by the sender using the key and decrypted by the receiver using the same key. This method works well if you are communicating with only a limited number of people, but it becomes impractical to exchange secret keys with large numbers of people. In addition, there

Ransomware Ransomware is a type of malware that limits access to a computer system that it affects. Just as its name goes, it then asks for ransom payment to pay to its creator in order for the limitation to be taken away. Some of these malwares encrypt files on the hard drive while others just lock up the system and display messages persuading the user to pay the ransom (Michael). There are two types of ransomware, one that locks the screen and displays a message that prevents you from

encryption with public-key encryption, including the strengths and weaknesses of each. Solution Scalability: with public-key encryption, multiple users can send encrypted messages to Alice using her public key and these messages can be decrypted only by Alice; thus, a linear number of publicprivate key pairs need to be established, distributed and protected to allow pairwise confidential communication between any two users; instead, symmetric encryption requires a quadratic number of secret keys. Efficiency:

Private key: A private key is a tiny bit of code that is paired with a public key to set off algorithms for text encryption and decryption. It is created as part of public key cryptography during asymmetric-key encryption and used to decrypt and transform a message to a readable format. Public and private keys are paired for secure communication, such as email. Explanation for private key A private key is shared only with the key's initiator, ensuring security. For example, A and B represent
