Answer 1

Group of answer choices.

A) the public key had been compromised.

B) the private key had been compromised.

C) the symmetric encryption key had been compromised.

D) the asymmetric encryption key had been compromised.

Answer:

C) the symmetric encryption key had been compromised.

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.

Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Email encryption is the encryption and authentication of an email to protect the message therein from being read by any person other than the intended recipients. Thus, it protects the email from hacking or invasion by a third party.

Basically, when the message is signed with the sender's private key, the receiver can verify its authenticity using the sender's public key.

Also, encrypting the email message with the receiver's public key provides confidentiality.

In this scenario, the most likely explanation for this result is that the symmetric encryption key had been compromised.

A host is on the 192.168.146.0 network that has a subnet mask of 255.255.255.0. The binary value of the host portion is 11010101. What is the decimal value of the host portion of the address?

Answers

Answer:

213

Explanation:

The given parameters are;

The network on which the host is on = 192.168.146.0

The subnet mast = 255.255.255.0

The binary value of the host portion = 11010101

To convert the binary value to decimal value, we proceed by multiplying each of the digits of the binary value by the corresponding power of 2, from the left to right, starting from a power of 0, and sum the result, as follows;

(11010101)₂ = (1×2⁷ + 1×2⁶ + 0×2⁵ + 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰)₁₀

1×2⁷+1×2⁶+0×2⁵+1×2⁴+0×2³+1×2²+0×2¹+1×2⁰= 128+64+0+16+4+1 = 213

∴ (11010101)₂ = (213)₁₀

The decimal value of 11010101 is 213.

[tex]K = {8}{x} ^{3} - {2}{y}^{ 6} \div {5}{d}+ {e}^{4} [/tex]

Answers

Answer:

v = sqr(t^(1/2)) - 4 * s / d^4

K = 8 * x^3 - 2 * y^6 / 5 * d + e^4

Explanation:

Given

[tex]v = \ \sqrt{t} ^{2} - 4s \div {d}^{4}[/tex]

[tex]K = {8}{x}^{3} - {2}{y}^{ 6} \div {5}{d}+ {e}^{4}[/tex]

Required

The equivalent in Q Basic

To solve this, we use the following rules:

+ , - and * are written as + , - and *

[tex]\div[/tex] is written as /

^ stands for raise to power

SQR is used for square

^(1/2) stands for square root.

So, the equivalents of the above statements are:

v = SQR(t^(1/2)) - 4 * s / d^4

K = 8 * x^3 - 2 * y^6 / 5 * d + e^4
