The usage of information systems within daily business and personal affairs for the transmission of confidential or even personal identifiable information, requires the usage of such as cryptography technology to secure the information. Three major forms of cryptography for digital transmission and data storage are hybrid, asymmetric, and symmetric cryptography algorithms, that provide security to protect the integrity, confidentiality, reliability, and authenticity of data transmissions and storage. (Rouse, 2008) However, each technology possesses individual traits and characteristics best suited for types of data transmission and storage. As symmetric key uses two identical keys for transmission and decryption, asymmetric employs a private …show more content…
(“Advantages and Disadvantages of Symmetric and Asymmetric Key Encryption Methods”, 2010) An advantage the transfer of keys, all users of asymmetric technology only publish the public-key, while the private key remains secret from general public knowledge. Digital signatures establish the medium for verification of the identity of the message, ensuring the sender is the appropriate personnel or organization. (Lander, n.d.) Additionally, allows the recipient of the digital signed message to verify the authenticity of the message, and the sender is unable to deny the origin of the message. Disadvantage, asymmetric users are required to verify their public authenticity, saying the public key actually belongs to them. Asymmetric encryption relatively slow when compared to other encryption methods like symmetric cryptography, and unsuitable for large file transfers. (“Advantages and Disadvantages of Symmetric and Asymmetric Key Encryption Methods”, 2010) The private key, the only method of asymmetric to decrypt an encrypted message is the through the usage of the private, if the private key no method is possible to decrypt the …show more content…
(Babu, Tianfu, n.d.) The system utilizes the paired key method from asymmetric with one glaring difference, the requirement to secure both the private and public key, to prevent compromise of data. The transferal of data within the system implements elements of session keys associated with symmetric technology, with public-key encryption serving as the decryptor of the symmetric key. (Cobb, 2008) Nevertheless, this addition provides the security feature that symmetric systems lacked to provide, a secure means of transmitting the paired keys from sender and receiver. Additionally, the encrypted symmetric key is the only key capable of decrypting the transmitted message, and the symmetric key is randomly generated so no key to agree upon. (Babu, Tianfu, n.d.) Hybrid cryptography implements two different encryption schemes, a key encapsulation scheme for the public-key, and a data encapsulation scheme for the symmetric
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 is normally 1024 or 2048 bits. However, in Asymmetric framework the keys with smaller than 2048bits are considered as not safe to use.
Bitcoins are portable. Mobile payments can be made almost instantaneously by using a digital wallet. Cross-border transactions may take only minutes. Other limitations that apply to transferring money are often irrelevant (such as delays due to public
PKC is the enabling technology for all Internet security and the increasing use of digital signatures, which are replacing traditional signatures in many contexts. However, RSA is better than PKC because RSA doesn’t need digital signature. As a result, the RSA algorithm turned out to be a perfect fit for the implementation of a practical public security system. In 1977, Martin Gardner first introduced the RSA system. After 5 years, company RSA used secure electronic security products. Nowadays many credit companies of all over the world use the RSA system or a similar system based on the RSA system.
The use of bitcoins provides independence from centralized authorities, such as governments and corporations. • Transactions using bitcoins are fast and efficient. • The use of bitcoins can provide anonymity to users. • Bitcoin mining provides an incentive for users to keep the currency running. Cons of using Bitcoins • The security and protection provided by large bodies is absent, making bitcoins a volatile and insecure means of trading.
A security certificate is like a special deportation warrant in which the Canadian government can deport any “non-Canadians” who they feel are a threat to Canada and its citizens. An example of this would be anyone that the Canadian government feels is involved with a terrorist group or organization will be deported using a security certificate. Some pros to the security certificate are it will help the Canadian government better protect Canada by deporting anyone who poses a serious threat to Canada, and its citizens. Another pro is it limited in use as security certificates have only been used 27 times since 1991, meaning the powers of the security certificates have not been abused as of yet. It is somewhat fair to the person a security certificate
Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors. They also have many business files or contracts that need to be strictly protected. Without data encryption, these important information may fall into wrong hands and be misused by others. Besides, data encryption may be used to secure sensitive information that exists on company networks, or create digital signatures, and help to authorize in business. No one should underestimate the importance of encryption. A little mistake in encryption may make sensitive information revealing, or even result in illegal and criminal accuse.
Secret Key (K): Secret key is used to encrypt the plain text . It is also input to the encryption function. In symmetric key encryption, only one key is used between sender and receiver. This secret key will shared by both using the secured channel.
One of the largest parts of commerce is transaction. Transactions are needed anytime two parties exchange money or information. Since the Information Age has begun, transactions are more common over the Internet, where it is more imperative that transactions are secure (Klein x). Corporations have also become more widespread, which means that cryptography is needed to secu...
While generations of today have witnessed countless technological advances, there are also downfalls to these progressions. Technology interferes with education, attention spans, relationships, social interactions, self esteem, and even creativity. In order for technology to have more pros than cons, it is pertinent to keep a clear perspective. Monitoring how much you or your children spend time using electronics is the key to making sure that technology is not harmful.
The Oxford English online dictionary defines technology: as the product of such application; technological knowledge or know-how; a technological process, method, or technique. Also: machinery, equipment, etc., developed from the practical application of scientific and technical knowledge. In the space of a few decades technology as experienced incredible growth and has become a crucial part of our everyday life. Most of us use technology in every aspect of our lives whether we are at work, school, or relaxing at home in our free time. Now most of us could not imagine returning to a time in which technology was not so readily available. Most of us expect to have access to information at a moment’s notice. There are many advantages and disadvantages to our obsession with technology.
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 decrypt the message. The IBM-created figure DES has been generally utilized yet is presently toward the finish of its helpful life and is expected for substitution. Whatever figure designers use in their applications, it's vital to consider the
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
How did technology affect us? Did it affect us in a positive or a negative way? Technology has both positive and negative effects, it’s plainly about how people choose to use it. Throughout these years, technology has been a great advancement for our country and it helped us develop in many ways that we can’t even count.
Technology has changed modern society drastically, both positively and negatively. Technology has influenced every aspect of our life, making it simpler but not necessarily better. Albert Einstein was concerned about the advancement of technology. "I fear the day that technology will surpass our human interaction."1 Undoubtedly, what has changed the most are communication, the spread of information, and how business is practiced. Consequently, practically everyone knows how to use a computer, connect to the Internet, or use a smartphone. This is demonstrated by the way the Internet is used daily by millions of people to communicate, to sell, advertise, retrieve, and share information. Thanks to the Internet, information from anywhere in the world is at our fingertips. As a result, the advancement of technology has changed our life in many ways including; sharing of information, communication, business, education, social interaction, simplifying everyday tasks, replacing basic skills and jobs.
In today’s world science and technology has made human life difficult just because of its new inventions. Everyday many new technologies are been added to the list. People get addicted and they don’t know what they are giving up in return. However, these technologies are taking away the human’s ability to think quantitively. Defining human in today’s world means substituting technology for work and thinking that humans used to do. For instance, the ability to count, the memory to remember, the ability to learn through classrooms, and the ability to do things by hand.
