EPS AES-based confidentiality and integrity algorithms: Complexity study

In the present paper, we are interested in the security functions and algorithms of the 3GPP 4G standard known as LTE. A special interest is given to the protection of the data integrity and the provisioning of data encryption. In a previous work, we were interested in the study of the cryptographic algorithms EEA1/EIA1 and EEA2/EIA2 operation and their implementation. The analytical study of the first set EEA1/EIA1 was carried out as well. In this paper, we will focus on the study of the time and space complexity of the second set of the LTE algorithms based on the block cipher AES.
