what technologies I can use to implement encryption on IoT and/or key fobs of vehicles?
The Internet of Things (IoT) brings a new set of security concerns. Unlike VPN encryption, which safeguards networks through an encrypted and anonymous tunnel, IoT devices must be inbuilt with their own strong security and encryption standards. VPN allocates an isolates space on the network. However, inside the VPN space, all the network nodes can be accessed by any participant. When IoT devices are out there, a VPN has many open doors.
1. The Data Encryption Standard (DES).
The U.S. Government National Institute of Standards and Technology (NIST) oversees this formal encryption method or DES. DES uses the same encryption key to encrypt and decrypt data. Both the sender and the receiver must have the same private key. The latter process is known as a symmetric key algorithm.The important difference between DES and AES (described below) is that DES is less secure than AES. In fact, DES encryption is a result of a 30-year-old effort by the U.S. government to provide cryptographic security for all government communications. The goal was to achieve both cryptographic security and standardization. DES is the cornerstone of cryptography, but has since been cracked by researchers.
2. The U.S. Government Advanced Encryption Standard (AES)
AES uses a single encryption key of varying lengths. The AES algorithm concentrates on a single block of data and re-encrypts it 10 to 14 times, depending on the key length.When using an internet connected medical device, AES meets U.S. Government requirements for HIPAA data protection. AES also meets FINRA standards for protecting financial records. AES is an efficient and elegant algorithm whose strength resides in its key length options. The longer the key length, the more exponentially difficult it is to break the encryption.
3. Triple Data Encryption Standard (DES).
This algorithm is a type of computerized cryptography where each block of data receives three passes. Additional security comes from the larger key length. Triple DES was replaced by NIST, which adopted the aforementioned AES. Triple DES is now considered obsolete, but is still used by some IoT products because of its compatibility and flexibility.What Triple DES does well is protect against brute force attacks. Brute force is an exhaustive effort (as opposed to intellectual strategies) through repeated trial and effort. Brute force attacks use automated tools to guess various combinations until the hacker cracks the key.
4. RSA Encryption.
The initials RSA come from the last names of three founders of RSA Data Security (Rivest, Shamir, and Adelman). RSA encryption employs a public key encryption technology licensed by RSA Data Security, who also sells its accompanying development kits.RSA encryption allows users to send encrypted information without having to previously share the code with the recipient. It is a public-key encryption, and the public key can be shared openly. However, the data can only be decrypted by another private key. Each RSA user has the common public key, but only designated recipients are privy to the private key.
5. Twofish Encryption Algorithm
Twofish is another block cipher algorithm proposed by Counterpane Labs over 20 years ago as a replacement for the AES. Twofish was a finalist for selection as the new NIST Advanced Encryption Standard, but was not selected.Twofish uses a block ciphering system based on a single key of any length up to 256 bits. This encryption standard is efficient on computers with lower capacity processors and IoT device smart cards. Twofish appears in many of the free encryption software products like VeraCrypt.

1. How can public-key encryption be used to distribute a secret key? What is the benefit of doing this?
Implement in Go language AES encryption mode CBC with providing the packages name for Go language. You can implement AES-ECB Mode (the basic AES) from crypto/aes package and crypto/cipher.Block. You can also get the SHA-256 hash function from crypto/sha256. You can get the secure random numbers generator from crypto/rand package. However, the you will implement both CBC mode and HMAC from scratch. You are NOT allowed to use any libraries or packages to implement these two things for you. You...
1. Data management, device management and network management of IoT is crucial to data integrity and transmission. T F 2. An IoT application is a set of wireless devices that act together to perform some sensing and control function. Most applications also provide a user interface, such as a mobile app or cloud-based service. In general, each application is deployed independently of any other applications that may be operating in the area and forms its own separate, cryptographically isolated network....
After looking at the RSA algorithm for asymmetric key encryption and decryption. And after looking at Diffie-Hellman Exchange and at the Elgamal encryption scheme that can use the key derived from the exchange. State the justification for having this alternate mechanism when RSA is already well established. Consider the security and the computational aspects of the schemes. Be as specific as possible.
Implement A CPA-secure construction for variable-length encryption; use CBC mode for domain extension.
As an IT professional, what are some key techniques you can implement to protect an organization from becoming a victim of cybercrime? Provide suggestions for educating others within the workplace and describe specific techniques they can use to be proactive in crime prevention.
I need an encryption algorithm that works fast on large files and doesn't increase the file size. It should use a key to encrypt/decrypt data. The files will be sent using REST and over HTTPS, but a good encryption/decryption method with a key is mandatory (to be used in a website). The files will be saved on a 3rd party servers, and although the files are sent through HTTPS, they must be stored encrypted on the remote servers and decrypted...
7) (i) You and Bob use Elgamal encryption with p=17 and g=3. You choose your private key a=4 and send A=-4 mod 17 to Bob (-4 is congruent to 3^4 mod 17), and Bob sends you (2,7). What is Bob's message? (ii) Alice and Bob use Elgamal encryption with p=13 and g=2. You noticed that Alice has sent A=11 mod 13 to Bob, and Bob has sent (5,7) to Alice. What is Bob's message?
