[amp_mcq option1=”allows anyone to decode the transmission” option2=”allows only the correct sender to decode the data” option3=”allows only the correct receiver to decode the data” option4=”does not encode the data before transmitting it E. None of the above” correct=”option3″]
The correct answer is: C. allows only the correct receiver to decode the data.
A public key encryption system is a cryptographic system that uses two keys, a public key and a private key, to encrypt and decrypt data. The public key is shared with everyone, while the private key is kept secret. Data encrypted with the public key can only be decrypted with the private key. This makes public key encryption systems ideal for secure communication, as it ensures that only the intended recipient can read the message.
Option A is incorrect because public key encryption systems do not allow anyone to decode the transmission. Only the recipient with the private key can decrypt the message.
Option B is incorrect because public key encryption systems do not allow only the correct sender to decode the data. The sender does not need to know the private key in order to encrypt the message.
Option D is incorrect because public key encryption systems do encode the data before transmitting it. The data is encrypted with the public key, which is then transmitted to the recipient. The recipient then uses their private key to decrypt the message.
Option E is incorrect because public key encryption systems are a type of cryptographic system.
