Securing transmitted data from UAV to Base Station in high bit rate with maximum security needs Authenticated Encryption. New One Time Pad (OTP) algorithm was designed for high bit rate and high security level applications such as UAV Data Link. In this paper, the designed OTP algorithm is combined with Authenticated Encryption to ensure encryption and authentication along with data integrity. Authenticated Encryption (AE) is a very important technique that ensures complete security procedures of transported data. This technique combines encryption, authentication and data integrity to provide both privacy and authenticity of the data. In this paper, the design, analysis and simulation of a fast and enhanced stream cipher Authenticated Encryption architecture which is called Authenticated Encryption New OTP (AENOTP) is introduced on the basis of unpredictability concept. Unpredictability concept is a concept based on dynamic use of encryption algorithms, where instead of using single encryption algorithm for producing the ciphertext, multiple encryption algorithms are used in the same structure. The proposed algorithm is faster than ASC-1 authenticated encryption stream cipher with 60%. The proposed algorithm can resist different types of cryptanalysis attacks such as linear, differential, algebraic attacks and other types of attacks.
