Digital Signature

If the documents are incorrect in some way this can have adverse effect on a business and documents can make a significant contribution to the effectness and efficiency of the business.

To address the problem, we need to compare and contrast the modern form of the postal service: electronic mail (e-mail). Although email is favorable because it makes communication remarkably fast and you can send things for “free”, in many ways the good old letter is better. We want to identify when and how the letter is better. Even though it is free to send an email, you still need access to internet and a computer, both in which cost hundreds of dollars, opposed to a letter where you can have everything you need to send a letter under a dollar. A letter is also hard evidence, it’s harder to forge than an email, since handwriting is unique, and typing is not. Computers can have many internal errors; the computer can crash, information can be lost or leaked to someone.

Public and private key is an encryption technique used to secure data. Explain the operation and use of any encryption technique from the list below.

With the ever increasing surge of digital communications and transactions, a tougher level of security is essential in order to safeguard the user and their data transactions. Systems, personal computers, mobile phones, servers, and even smart cards are all being used everywhere and there is a need to secure communications. With the influx of data management, there is a clear race between the two challengers in the game known as Information Security between developers and the hackers. PKI was designed to influence the Internet infrastructure for means of communication (Samuelle, 2011). While decreasing antagonistic misuse of data, reducing data theft, and providing an extra layer of trust through key pairs and

1) Digital Certificates: Digital authentications are settled upon information structures that join qualities of an association with having its relating open key. The key necessity for a Digital Certificate is the reality it should be approved upon by recognition} expert (CA). By being marked by a perceived and trusted specialist an electronic computerized testament gives the certification

30. What is the process of confirming a user’s identity by using a known value, such as a password, pin number on a smart card, or user’s fingerprint or handprint in the case of biometric authentication? Authentication

Step:1 Choose two large primes from random x,y Step:2 find the system modules N= x.y: *(N)=(x- 1)(y-1) Step3: encryption key e lies in 1<e<*(N),gxy(e,*(N)=1 Step4: Decryption key d is calculated then e.d=1, mod*(N) and 0 ≤ d ≤ N. Step5: Public encryption key KE= {e,N} Step6: Private decryption key KD= {d,x,y} Step7: For encrypting the document DC first receive the public key, KE= {e, n},

21.) Digital certificate A digital certificate is an electronic "passport" that allows a person, computer or organization to exchange information securely over the Internet using the public key infrastructure (PKI). A digital certificate may also be referred to as a public key certificate.

a fee is charged for the service of issuing and validating identities using a digital signature.

The X.509 formatted public key certificate is one of the most important components of PKI. This certificate is a data file that binds the identity of an entity to a public key. The data file contains a collection of data elements that together allow for unique authentication of the own ingenuity when used in combination with the associated private key.

Encyption takes data and transforms it into unreadable jargon until a key is used to unlock or decrypt the data back to its original form. Due to its near infallibility, encryption is one the most best ways to secure data (Williams & Sawyer, 2015).

The hash is encrypted with Person A’s Private Key (in this case it is known as the Signing Key) to create the Digital Signature.

Section 10 defines the conditions if a change or error in an electronic record occurs in a transmission between parties to a transaction

What do you need if you want to decrypt encrypted messages and files from a trusted sender? PKI – Public Key Infrastructure

A standard PKI consists of several components: hardware, software, policies and standards, administration, distribution of keys and digital certificates. Digital certificates are at the heart of PKI as they confirm the identity of the certificate subject and bind that identity to the public key contained in the certificate. A typical PKI includes several key elements. A trusted party, known as a certificate authority or CA, acts as the root of trust and provides services that authenticate the identity of
