In this brief paper, we introduce encryption-free message authentication based entirely on fast one-way hash functions. Two methods are presented and their strength is analyzed. The security of the proposed methods is based on the strength of the underlying one-way hash function....

The two most common forms of MAC algorithms are the CBC-MAC (now implemented per the OMAC1 algorithm and called CMAC in the NIST world) and the HMAC functions. The CBC-MAC (or CMAC) functions use a block cipher, while the HMAC functions use a hash function. This book covers both NIST...
A cryptographic hash function H is a function which takes arbitrary length bit strings as input and produces a fixed-length bit string as output; the output is often called a digest, hashcode or hash value. Hash functions are used a lot in computer science, but the crucial difference between...
The wireless device obtains the input message. The wireless device generates a keystream. The wireless device computes a message authentication code using the keystream and a universal hash function. The universal hash function is computed using carryless multiplication....
The protocol uses the hash function and elliptic curve encryption (ECC) point addition operation to realize mutual authentication between users and servers. Recently, research on the 𝐼𝑜𝐷 has been widely conducted [33,34,35]. All the architectures proposed in the above literature are for ...
Secret keys.They must have a way to decode messages they get. A secret key handles this task, and it's meant to stay secret and hidden. Algorithm.They must pick one hash function that all of their messages will move through. When complete, the messageis considered irreversible, and it's...
public function handle($request, $next) { return Auth::onceBasic() ?: $next($request); } }Next, register the route middleware and attach it to a route:Route::get('/api/user', function () { // Only authenticated users may access this route... })->middleware('auth.basic.once');...
Passwords hashed using the Secure Hash Algorithm (SHA) cryptographic hash function SHA-1. Oracle Database uses the SHA-1 verifier is to authenticate the user password and establish the session of the user. In addition, it enforces case sensitivity and restricts passwords to 160 bits. The advant...
This route will be responsible for validating the password and redirecting the user to their intended destination:use Illuminate\Http\Request; use Illuminate\Support\Facades\Hash; use Illuminate\Support\Facades\Redirect; Route::post('/confirm-password', function (Request $request) { if (! Hash::...
