“…So, AES-256 which has a key length of 256 bits, supports the largest bit size and is virtually unbreakable by brute force based on today's computing standards, making it, to date, the strongest encryption standard. Even using a host of super-powered computers, cracking a 256-bit AES key would take longer than the assumed age of the universe [18][19][20][21][22][23][24][25][26].…”

Cryptography, a scientific field that has existed even before the beginning of computer science. This article looks at the development symmetric crypto-system, which falls within the framework of image security, by Advanced Encryption Standard (AES- Advanced Encryption Standard) algorithms. AES algorithm is not integrity protected. Cryptanalysis could use modified encrypted image of each ciphered bloc for generating oracle and getting the key. A new crypto-system uses hash function named AES-GCM (Advanced Encryption Standard-) for solving this problem. Using Galois Counter Mode (GCM) combined with Secure Hash Algorithm 256 bits (SHA-256) or BLAKE2s hash function, the old mode of ciphering like: Cipher FeedBack (CFB), Output FeedBack (OFB), Cipher Block Chaining (CBC), Electronic Codebook Block (ECB) and CounTeR (CTR) mode encryption, will increase the security level at confidentiality and integrity. In this article, robustness of the crypto-system will be evaluated by multiple criteria, indeed the statistical analysis, sensitivity measurement and performance measurement. For the statistical analysis, the histogram is flat and the correlation between adjacent pixel is not linear for the encrypted image. The relation between clear image and encrypted image doesn’t exist. For the sensitivity analysis, Number of Pixel Changing Rate (NPCR) and Unified Averaged Changed Intensity (UACI) permit to avoid differential attack of the crypto-system. The two values are respectively near 99% and 30%. For performance measurement, the similarity of the decrypted image and original image will be tested. The Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) are equals of infinity and zero. The decrypted image and original image are the same. The integrity of the image on the crypto-system will be evaluated by modifying one bit of the encrypted image. The decryption process doesn’t give decrypted image and show that the tag value is incorrect.

“…WPA3 is a subset and the latest improvement of the 802.11i security standard of WLAN technology for personal and enterprise networks. WPA3 enhances the encryption of wireless networks using a new encryption protocol called Galois Counter Mode Protocol (GCMP) with Advanced Encryption Standard (AES) [12]. In addition, WPA3 improves the authentication of wireless networks by dealing with Simultaneous Authentication of Equal (SAE is defined as a secure key establishment protocol) with a length key equal to 128 or 192 bits to submit stronger defenses against password guessing where WPA2 was dealt with pre-shared key (PSK).…”

“…Initialization Vector (IV), additional authenticated data, secret key, and plaintext are used as input in 128-bit and give a 128-bit ciphertext and authentication tag. AES-GCM algorithm can encrypt or decrypt with a 128-bit or 192-bit of cipher key [12]. The algorithm that is adopted to provide the authentication and integrity in WPA3 is the hash message authentication code (HMAC).…”

The wireless local area network technologies are attractive solutions to upgrade the communication network of the traditional electrical substation toward smart electrical substation. Unfortunately, the wireless communication network suffers from additional drawbacks compared to wired technologies such as cyber threats in particular the common wireless channel. The current work suggests a cybersecurity model for the wireless communication network (WCN) that serves the substation automation system (SAS) of electrical substations. The adopted model protects the wireless communication between the high-voltage devices and the switched access point (S-AP) in the electrical substation using wifi protected access 3 (WPA3) security scheme. This work proposes a new architecture scheme to provide a secure and reliable key management module based on WPA3. Hence, a local authenticator is responsible for distributing the keys safely rather than the remote authentication dial-in user service (RADIUS) server. In addition, a lightweight security scheme as possible is handled to overcome the challenges of SAS system performance requirements. The results indicated that the adopted ciphering algorithms do not break the latency requirements of real-time protection of SAS (less than 4 msec).

“…This may have resulted from the operation of the Galois/Counter Mode (GCM) block encryption. (17)(18)(19) In the GCM block encryption, the message authentication code (MAC) value should be added to the message, which requires 16 bytes to verify the identity. (20) When the message content is small, adding the MAC value is more likely to affect the transmission speed, resulting in a long time for the encryption process.…”

Toward improving water pipe leakage detection, we use an ESP32 board, sensors, and Internet of Things (IoT) technology to achieve the flow rate detection and throttling of water. We use a Message Queuing Telemetry Transport server as a broker to receive and transmit the flow data and leakage alarm, respectively. The leakage detection and LINE notification are realized using a Python program. For the information security of IoT, we use Galois/Counter Mode block encryption for packaging IoT messages. The transmission speed of the encrypted message has no notable difference from that of the unencrypted one when the content exceeds 1000 bytes.
