Answer:There are 3 programming/pseudocode constructs:

1. Sequence: It refers that instructions should be executed one after another.

2. Selection: This construct is used to make a decision in choosing an option from

many available options on the basis of a condition. So, if a condition is true then one

option would be chosen while if a condition is false then another option will be

chosen.

3. Repetition: This construct is used to repeat a block of code as per the given

Consider the following code segment.

mafiozo [28]

Answer:

for (int h = k; h >= 0; h--)

Explanation:

From the list of given options, option C answers the question.

In the outer loop

Initially, k = 0

In the inner loop,

h = k = 0

The value of h will be printed once because h>=0 means 0>=0 and this implies once

To the outer loop

k = 1

The inner loop will always assume value of k;

So,

h = 1

This will be printed twice because of the condition h>=0 means 1>=0.

Since 1 and 0 are >=0; 1 will be printed twice

To the outer loop

k = 2

The inner loop

h = 2

This will be printed thrice because of the condition h>=0 means 2>=0.

Since 2, 1 and 0 are >=0; 2 will be printed thrice

To the outer loop

k = 3

The inner loop

h = 3

This will be printed four times because of the condition h>=0 means 3>=0.

Since 3, 2, 1 and 0 are >=0; 3 will be printed four times

Vikki [24]

Answer: a)True

Explanation:

Hardware is the component of computing system that contains physical devices and parts through which commands are given by user by touching or pressing the physical device.E.g- keyboard, mouse etc.
Software is the program set or series of instructions that is run in the form of command to get executed in computing system.It carries out to instruction to perform tasks.E.g-application of computer
Other option is incorrect as the statement is true.
Thus, the correct option is option(a).

A company is executing a strategy to encrypt and sign all proprietary data in transit. The company recently deployed PKI service

Softa [21]

Answer:

A. S/MIME

B. TLS

C. Kerberos

Explanation:

PKI : Public Key Infrastructure is a technique which will allow services or applications to communicate securely across the unsecured network or internet.

PKI mainly consist of CA or Certificate Authority who can issue digital certificates or they are also known as trusted CA. exmaples are godaddy, digicert, verizone, symmantec, etc.. and RA also known as Registration Authorities and they verify if the requested certificates can be stored at CA. Keys will be stored in the central directory.It will also consists of certificate management system and the policies governing PKI.

S/MIME : Secure/Multipurpose Internet Mail Extensions which use assymentric cryptography and sign the MIME data. S/MIME will provide services like Authentication, Encryption , Integrity, Privacy and Non repudiation for messaging applications

SMIME uses certificates which can be self signed or CA certified. It specifies MIME type as $application/pkcs7-mime$ while transmitting the data.

TLS : Transport Layer Security. the earlier versions used to be known as SSL ( Secure Socket Layer) SSLv3 got depreciated and TLSv1.2/1.3 are popularly used to provide encryption, authentication, Integrity and Hashing for client to server side communication.

Most of the applications communicate securely using TLS. They will establish secure TCP connection using SSL Handshake. During the Handshake they will exchange supported versions, ciphersuites and certificates. Applications which uses TLS always uses CA certificates and Inhouse applications can communicate using self signed certificate or even with CA certificates.

HTTPS which is also known as HTTP over SSL is widely used for almost all the web services to communicate securely across the internet.

Kerberos : It is a protocol used to prove the identity for two nodes which are communicating with each other. Kerberos uses both symmetric key cryptography and assymetric key cryptography. However, symmetric key cryptography is used widely and public key cryptography is used optionally.

Authentication server which is also known as AS is used to authenticate the requesting client. It further forwards the user credentials to key distribution center. KDC further issues to TGT ( ticket granting ticket) and it uses TGS's secret key to encrypt. User will receive a encrypted output.

When a User Login then The client authenticates itself to the Authentication Server (AS) which forwards the username to a key distribution center (KDC). The KDC issues a ticket-granting ticket (TGT), which is time stamped and encrypts it using the ticket-granting service's (TGS) secret key and returns the encrypted result to the user's workstation. Sessions will be renewed and managed by users session manager.
