Novel algorithm may improve security against fraudulent online transactions

New Delhi: A new digital security algorithm can make it tougher for cyber-attackers to beat user-authenticity tests such as one-time passwords (OTPs) and CAPTCHA, scientists say.

The algorithm, called BaReNPI, uses a software-based random number generator that makes it more difficult for cyber-attackers to crack compared to Advanced Encryption Standard 256 (AES 256) — the current gold standard for electronic cryptographic encryption, the researchers said.
