INTRODUCTION: The main purpose of computer networks is to understand the principles of network security. Users want to exchange the data in a secure way. The problem of network issue is a complex issue. Network security means a protection of the network assets. POPULAR NETWORKS: UUCP: Unix to...

When Office uses CryptoAPI, the encryption algorithms depend on the specific algorithms that are available in a Crypto Service Provider (CSP), which is part of the Windows operating system. The following registry key contains a list of CSPs that are installed on a computer: ...

The test was executed with 2048 bit RSA, with 100k repeats per probe, in a VM on a fairly noisy/busy 2.3GHz Icelake Xeon system. The measured side channel is about 400ns, so it should be fairly easy to exploit even over remote network connections. ...

in ATM (asynchronous transfer mode) network security and IPSec (IP security). A counter, equal to the plaintext block size is used. The only requirement stated in SP 800-38A is that the counter value must be different for each plaintext block that is encrypted. Typically the counter is ...
