java program for congestion control using leaky bucket algorithm
The main concept of the leaky bucket algorithm is that the output data flow remains constant despite the variant input traffic, such as the water flow in a bucket with…
Java program for simple RSA algorithm to encrypt and decrypt the data
The RSA algorithm can be used for both public key encryption and digital signatures. Its security is based on the difficulty of factoring large integers.The RSA algorithm’s efficiency requires a…
