E Commerce And The NEED FOR Encryption Computer Research Essay

Web-commerce is continuing to grow into one of the fastest-growing part of industry before two years. Billions of dollars have transferred hands along the way and each entrepreneur wants a cut of the dough. To make this possible, data encryption plays an extremely central role in guaranteeing customers that spending money on anything online is secure.

E-commerce relies on encryption to secure data transmitting by managing data gain access to and protect information on the internet and in the end improve consumer self-assurance. Encryption is the encoding of data using an algorithm such that it is incomprehensible to anyone in the event that the data transmission is intercepted, unless the key is known to enable document decryption. By implementing encryption, integrity is preserved while digital authentication is enforced, thus, allowing both customers and sellers to verify the personal information of the other party, a concept fundamental to secure online bank card transactions. The reliability of e-commerce website may be adversely impacted if fraud of customer information occurs, especially high-risk since 90% of most online payments are dealt by credit cards.

4. Important of Encryption

Cryptography is a method of mathematically encoding used to transform messages directly into an unreadable format in an effort to maintain confidentiality of data. Cryptography comprises a family of technologies that include the following

Encryption transforms data into some unreadable form to ensure personal privacy.

Decryption is reverse of encryption; it changes encrypted data back to original, intelligible form.

Authentication recognizes an entity such as a person, a machine on the network or an organization.

Digital signatures blind a file to the possessor of a specific key and are the digital equivalent of paper signatures. Signature confirmation is the inverse of a digital signature; it verifies that a particular personal is valid.


In order to enable secure online business deal, data encryption takes on four important functions

Digital authentication which allows both customers and the vendor to make sure that they are dealing with whom, the other get together promises to be. These is absolutely necessary before sending charge card details to the seller and also allow retailers to confirm that the customer is the real owner of the credit-based card getting used.

Integrity ensures that the information received re not altered during transmission by any third party.

Non-repudiation avoids customers or retailers denying they ever received or delivered a particular subject matter or order.

In the event that information is intercepted, encryption ensures privacy that avoids third functions from reading and or using the info to their own edge.

Two methods of encryption network traffic on the web are SSL and S-HTTP. Secure Outlet Layer (SSL) and its own successor Transport Layer security (TLS) allow customer and server computers to control encryption and decryption activities as they talk to each other during a secure web procedure. Secure Hypertext Transfer Protocol (S-HTTP) is another protocol used for encrypting data streaming over the internet, but it is bound to individual emails, whereas SSL and TLS are designed to establish a secure interconnection between two personal computers.

The capacity to generate secure trainings is made into Internet client web browser software and machines, and occurs automatically with little customer intervention. Your client and the server work out what key and what degree of security to make use of. Once a secure treatment is established between your customer and the server, all announcements in that treatment are encrypted.

There are two different ways of encryption: symmetric key encryption and general public key encryption. In symmetric key encryption, the sender and the device establish a secure Internet procedure by creating an individual encryption key and sending it to the recipient so both the sender and device talk about the same key. The effectiveness of the encryption key is assessed by its nit duration. Today a typical key will be 128 bits long (a string of 128 binary digits).

The problem with all symmetric encryption plans is that the key itself must be distributed somehow on the list of senders and receivers, which exposes the key to outsiders who could just be able to intercept and decrypt the main element, A more secure form of encryption called general public key encryption uses two secrets: one shared (or consumer) and one totally private, 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 text messages, communicators first create different pairs of private and public keys. The public key is stored in a website directory and the private key must be placed key. The sender encrypts a message with the recipients general public key. On receiving the subject matter the recipient uses his or her private key to decrypt it.

Digital signatures and digital certificates further benefit authentication.


Most firms implement multiple forms of security by using hardware alternatives such as routers and firewalls. These devices protect essential data by keeping external threats from the network. Sadly, burglars will employ numerous disorders, specifically directed at your information. When attackers discover a way to go into your first type of defense, data encryption steps up and helps to ensure that your secrets can't be viewed.

Encryption has modified significantly over the years, heading from a armed forces way to widespread general public use. Be it hardware or software-based, this method is fast, simple to operate & most important, secure. Here a few of the main element benefits this solution offers

Power: The very best in data encryption is dependant on global standards, in a position to mitigate potential corruption without flaw. Many solutions are large enough to ensure an entire business is in full conformity with security procedures. Data encryption allows a firm to attain military-level security with easy and affordable solutions.

Flexibility: Data encryption can protect your very sensitive information be it stored on the desktop or laptop computer, a PDA, detachable storage media, a contact server or even the corporate network. This allows one to securely access important data from the office, on the highway or at home. If the device is lost or stolen, the info will be guarded by the info encryption mechanism.

Transparency: It wouldn't be considered a good idea to employ any security measure that negatively effects your business. A competent data encryption solution permits your business to stream at a normal pace, silently obtaining vital data in the backdrop. Among the better options are those running effectively without the user even being aware.

There are numerous benefits associated with data encryption as this solution provides stable protection in the event of a security breach. Not merely would it offer peace of mind, it also frees up resources normally employed by your perimeter defenses. Every security solution you set in place is important yet inefficient if confidential data itself is not protected.


Encryption is often oversold as the solution to all or any security problems or to threats that it does not address. Alas, encryption offers no such safeguard. Encryption does nothing to protect against many common ways of attack including the ones that exploit bad default settings or vulnerabilities in network protocols or software -- even encryption software. In general, methods apart from encryption are had a need to keep out intruders. Secure Computing Corporation's Sidewinder system defuses the forty-two "bombs" (security vulnerabilities) in Cheswick and Bellovin's e book, Firewalls and Network Security (Addison Wesley, 1994), without utilizing any encryption.
