A news company is planning to use a Hardware Security Module (CloudHSM) in AWS for secure key storage of their web applications.

lakkis [162]

Answer:

you cannot obtain a new copy of the keys that you have stored on Hardware Security Module, because they are lost forever and a new copy cannot be obtained if a copy is not kept somewhere.

Explanation:

Hardware Security Module (CloudHSM) is a cloud-based hardware security module (HSM) that provides the user the opportunity to create and utilize your own encryption keys on the AWS Cloud. It is a fully managed service that takes care of time-consuming administrative activities such as software patching, backups, hardware provisioning, and high-availability for the user.

One of the key elements of the Hardware Security Module (CloudHSM) is that a copy of the keys stored must be kept somewhere because if keys are lost, they are lost forever and a new copy cannot be obtained if a copy is not kept.

Therefore, you cannot obtain a new copy of the keys that you have stored on Hardware Security Module, because they are lost forever and a new copy cannot be obtained if a copy is not kept somewhere.

Consider a pipelined than can issue up to one instruction per cycle, but fewer may be issued because of pipeline hazards, multi-

a_sh-v [17]

Answer:

Achieved Instruction per cycle rate is $4.11\times 10^{15}$

Solution:

As per the question:

Execution time, t = 1.4 s

No. of instructions being executed, n = 1.8 billion =

Clock speed of CPU, f = 3.2 GHz = $3.2\times 10^{9} Hz$

Now, to calculate the actual issue rate achieved:

CPI (Cycle per Instruction) = $\frac{t}{n\times f}$

CPI = $\frac{1.4}{1.8\times 10^{6}\times 3.2\times 10^{9}}$

Instruction per cycle is given as the reciprocal of CPI:

Instruction per cycle = $\frac{1.8\times 10^{6}\times 3.2\times 10^{9}}{1.4} = 4.11\times 10^{15}$
