Enhanced Tiny Encryption Algorithm with Embedding (ETEA)

Abstract

As computer systems become more pervasive and complex, security is increasingly important. Secure Transmission refers to the transfer of data such as confidential or proprietary information over a secure channel. Many secure transmission methods require a type of encryption. Secure transmissions are put in place to prevent attacks such as ARP spoofing and general data loss. Hence, in order to provide a better security mechanism, in this paper we propose Enhanced Tiny Encryption Algorithm with Embedding (ETEA), a data hiding technique called steganography along with the technique of encryption (Cryptography). The advantage of ETEA is that it incorporates cryptography and steganography. The advantage proposed algorithm is that it hides the messages.

AL-TEA: Alternative Tea Algorithm for Healthcare Image in IoT

“…In order to do this, we conducted a set of randomness and security experiments, which are detailed in this article [6]. The use of the same key in all stages of encryption is one of the fundamental drawbacks of TEA and its numerous modified variations, which leads to a reduction in security, as evidenced by the avalanche effect of the algorithm [7]. Furthermore, text encoding and decoding take a long time, reducing the embedded IoT network's efficiency.…”

“…Furthermore, the cipher and decipher time consuming is high, leading to diminished TEA efficiency [4]. Therefore, for providing an improved security mechanism, researchers in [5] suggested an improved tiny encryption algorithm with embedding (ETEA), a method of data hiding beside the technique of cryptography are employed in this algorithm. The gain of ETEA is that it combines cryptography and steganography.…”
