Q71.
What happens when an end user purchases a program protected by a crypto-processor?

a.

The end user decrypts the program using a private key

b.

The program binaries are decrypted using a public key

c.

The software developer requests the user’s processor serial number and obtains the private key

d.

The program binaries are encrypted using the public key and shipped or transmitted to the end user

Discuss
Answer: (d).The program binaries are encrypted using the public key and shipped or transmitted to the end user Explanation:The program binaries are encrypted using the public key and shipped or transmitted to the end user.
Q72.
Where is the decrypted code stored in the crypto-processor approach?

a.

In a special memory region that is not software-accessible

b.

In the end user’s computer hard drive

c.

In a cloud server

d.

In the crypto-processor manufacturer’s database

Discuss
Answer: (a).In a special memory region that is not software-accessible Explanation:The crypto-processor decrypts the code using the internally stored decryption key (the user’s private key) and stores the decrypted code in a special memory region that is not software-accessible.

Q74.
What is the first step in protecting a program using a crypto-processor?

a.

Assigning each processor a pair of encryption keys and a serial number

b.

Requesting the user's processor serial number

c.

Contacting a trusted authority to obtain the public key for a processor serial number

d.

Encrypting the program binaries using the public key

Discuss
Answer: (a).Assigning each processor a pair of encryption keys and a serial number Explanation:The first step in protecting a program using a crypto-processor is to assign each processor a pair of encryption keys and a serial number.
Q75.
How is a program protected using a crypto-processor?

a.

The program binaries are encrypted using the public key and shipped to the user

b.

The crypto-processor decrypts the code and stores the decrypted code in a special memory region

c.

The processor executes the decrypted code directly from inaccessible memory

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:A program is protected using a crypto-processor by encrypting the program binaries using the public key, the crypto-processor decrypts the code and stores the decrypted code in a special memory region, and the processor executes the decrypted code directly from inaccessible memory.
Q76.
What is the problem with encrypting and decrypting a protected program using a crypto-processor?

a.

The data generated by the program can be used to expose information about the encrypted program

b.

The decryption process is too slow

c.

The encryption process is too complex

d.

The program may not execute properly when encrypted

Discuss
Answer: (a).The data generated by the program can be used to expose information about the encrypted program Explanation:The data generated by a program can be used to expose information about the encrypted program, which is a problem with encrypting and decrypting a protected program using a crypto-processor.
Q77.
