In all cases except during the book keeping cycle of the algorithm, the number of message exchanges per Critical Section execution is less than or equal to 5. Only during the book keeping cycle which is not done very often the number of message exchanges per Critical Section execution reaches...
Here I wish to show you some of my DIY demo programs demonstrating howCritical Section Problemscan be solved by using Peterson's Algorithm, Spinlocks as well as Semaphores. This is a demo program ofPeterson's Algorithm. Here two clients send messages to their corresponding server threads, and ...

The encryption algorithm is controlled by the provider name ("RijndaelManaged") that corresponds to settings in the configuration file specifying the type of symmetric algorithm to use.The Key field in the configuration holds the encryption key. This key is stored in the configuration file but is ...
Peterson’s Algorithm:Peterson’s Algorithm is a solution to the Critical Section Problem in os for two processes. It uses shared memory and atomic instructions (such as test-and-set) to ensure that only one process can enter the critical section at a time. ...
Using a stronger algorithm to validate the integrity of requests and responses.What versions of SMB are impacted by this vulnerability? The issue addressed by this vulnerability affects both SMBv1 and SMBv2.Can this vulnerability be exploited using Internet Explorer? No. However, this issue may ...
In all forms of cryptography, a value known as a key is used in conjunction with a procedure called a cryptoalgorithm to transform plaintext data into ciphertext. In the most familiar type of cryptography, secret-key cryptography, the ciphertext is transformed back into plaintext using the ...
Clinical pathogen diagnostics from metagenomics data is a highly relevant translational problem requiring computational processing57. To raise awareness, we offered a concept challenge (Methods): a short-read metagenome dataset of a blood sample from a patient with hemorrhagic fever was provided for part...
