Question 1 of 30

In a smart city environment, a municipal IoT system is designed to collect and transmit data from various sensors, such as traffic cameras and environmental monitors. To ensure the confidentiality and integrity of the data being transmitted, the city planners decide to implement a combination of symmetric and asymmetric encryption methods. If the symmetric key used for encrypting the data is 256 bits long and the asymmetric key pair consists of a public key of 2048 bits and a private key of 2048 bits, what is the total key length in bits used for securing the data transmission in this system?

2304 bits

2048 bits

256 bits

512 bits
