E Commerce And The Importance Of Encryption Computer Science Essay

E Commerce And The Importance Of Encryption Computer Science EssayWeb-commerce has grown into star of the fastest-growing atomic number 18a of industry in the past two years. Billions of dollars have passed hands in the process and to distributively one entrepreneur wants a slice of the dough. To make this possible, development encoding plays a very central routine in ensuring customers that paying for anything online is fix.E-commerce relies on encoding to secure selective information transmission by controlling info access and protect information on the internet and in the end improve consumer confidence. Encryption is the encode of data development an algorithm such that it is incomprehensible to anyone in the solution that the data transmission is intercepted, unless the list is known to enable file decryption. By implementing encryption, integrity is maintained while digital authentication is enforced, thus, allowing twain customers and sellers to verify the ide ntity of the other party, a concept fundamental to secure online credit card transactions. The reliability of an e-commerce website may be negatively impacted if theft of customer information occurs, especially risky since 90% of all online payments are dealt by credit cards.4. Important of Encryption cryptogram is a method of mathematically encoding utilise to transform messages in to an unreadable format in an effort to maintain confidentiality of data. Cryptography comprises a family of technologies that include the followingEncryption transforms data into some unreadable form to ensure privacy. decryption is ral portsse of encryption it transforms encrypted data back into original, intelligible form.Authentication identifies an entity such as an individual, a instrument on the network or an organization.Digital signatures blind a document to the possessor of a finicky key and are the digital equivalent of paper signatures. Signature verification is the inverse of a digital s ignature it verifies that a particular signature is valid.ApplicationIn order to enable secure online transaction, data encryption plays four important functionsDigital authentication which allows both the customers and the merchant to be sure that they are dealing with whom, the other party claims to be. These is absolutely necessary before sending credit card details to the seller and also allow sellers to verify that the customer is the real owner of the credit card world utilise.Integrity ensures that the messages received re not changed during transmission by any third party.Non-repudiation pr purgets customers or merchants denying they ever received or sent a particular message or order.In the event that information is intercepted, encryption ensures privacy that prevents third parties from reading and or using the information to their own advantage.Two methods of encryption network traffic on the web are SSL and S-HTTP. Secure Socket shape (SSL) and its successor Transpor t Layer aegis (TLS) enable invitee and server computers to manage encryption and decryption activities as they communicate with each other during a secure web session. Secure Hypertext Transfer Protocol (S-HTTP) is another protocol used for encrypting data flowing over the internet, but it is limited to individual messages, whereas SSL and TLS are designed to establish a secure connection between two computers.The capability to generate secure sessions is built into Internet client browser software and servers, and occurs automatically with little user intervention. The client and the server negotiate what key and what direct of hostage to use. Once a secure session is established between the client and the server, all messages in that session are encrypted. at that place are two alternative methods of encryption symmetric key encryption and overt key encryption. In symmetric key encryption, the sender and the receiver establish a secure Internet session by creating a single en cryption key and sending it to the receiver so both the sender and receiver share the same key. The strength of the encryption key is measured by its nit length. Today a typical key will be 128 bits long (a string of 128 binary digits).The fuss with all symmetric encryption schemes is that the key itself must be shared somehow among the senders and receivers, which exposes the key to outsiders who world power just be able to intercept and decrypt the key, A more secure form of encryption called public key encryption uses two keys one shared (or public) and one totally one-on-one, as shown in Figure. The keys are mathematically related so that data encrypted with one key can be decrypted using only the other key. To send and receive messages, communicators first create separate pairs of private and public keys. The public key is kept in a directory and the private key must be kept secret. The sender encrypts a message with the recipients public key. On receiving the message the re cipient uses his or her private key to decrypt it.Digital signatures and digital certificates further help with authentication.Benefits/AdvantagesMost corporations implement multiple forms of security by using computer hardware solutions such as routers and firewalls. These devices protect essential data by care external threats out of the network. Unfortunately, burglars will employ numerous attacks, specifically targeted at your information. When attackers find a way to enter your first line of defense, data encryption steps up and helps to ensure that your secrets cant be viewed.Encryption has changed significantly over the years, going from a military solution to widespread public use. Whether its hardware or software-based, this method is fast, easy to use and most important, secure. Here some of the key benefits this solution offers origin The best in data encryption is based on global standards, able to mitigate potential corruption without flaw. Many solutions are large en ough to ensure that an entire organization is in liberal compliance with security policies. Data encryption allows a corporation to achieve military-level security with easy and affordable solutions.Flexibility Data encryption can protect your sensitive information whether its stored on a background knowledge or laptop computer, a PDA, removable storage media, an email server or even the integrated network. This allows you to securely access important data from the office, on the road or at home. If the device is lost or stolen, the information will be protected by the data encryption mechanism.Transparency It wouldnt be a good idea to employ any security measure that negatively impacts your business. An efficient data encryption solution enables your business to flow at a normal pace, silently securing crucial data in the background. Some of the best options are those running effectively without the user even being aware.There are many benefits of data encryption as this solut ion provides solid protection in the event of a security breach. Not only does it offer peace of mind, it also frees up resources normally used by your perimeter defenses. Every security measure you set in place is important but inefficient if confidential data itself is not protected.LimitationsEncryption is often oversold as the solution to all security problems or to threats that it does not address. Unfortunately, encryption offers no such protection. Encryption does nothing to protect against many commonalty methods of attack including those that exploit bad default settings or vulnerabilities in network protocols or software even encryption software. In general, methods other than encryption are needed to keep out intruders. Secure compute Corporations Sidewinder system defuses the forty-two bombs (security vulnerabilities) in Cheswick and Bellovins book, Firewalls and Network Security (Addison Wesley, 1994), without making use of any encryption. endpoint
