Cybersecurity Breakthrough,Cybersecurity is very important

New Cipher System Protects Computers Against Spy Programs

Kabari99-Cybersecurity is important because it protects all categories of data from theft and damage. This includes sensitive data, personally identifiable information (PII),

protected health information (PHI), personal information, intellectual property, data, and governmental and industry information systems.

Without a cybersecurity program, your organization cannot defend itself against data breach campaign

Which makes it an irresistible target for cybercriminals.

Both inherent risk and residual risk are increasing, driven by global connectivity and usage of cloud services,

like Amazon Web Services, to store sensitive data and personal information. Widespread poor configuration of cloud services paired with increasingly sophisticated cyber criminals

means the risk that your organization suffers from a successful cyber attack or data breach is on the rise.

Business leaders can no longer solely rely on out-of-the-box cybersecurity solutions like antivirus software and firewalls,

cybercriminals are getting smarter and their tactics are becoming more resilient to conventional cyber defenses.

It’s important to cover all the fields of cybersecurity to stay well-protected.

Cyber threats can come from any level of your organization.

Workplaces must include cybersecurity awareness training to educate staff about

common cyber threats like social engineering scams, phishing, ransomware attacks (think WannaCry),

and other malware designed to steal intellectual property or personal data.

a new cipher for cache scrambling that overcomes cache side-channel attacks and offers strong security with excellent performance.

SCARF implementations can significantly improve computer security,

and their practicality is validated through rigorous evaluation, paving the way for a more secure information society.

A team of researchers from around the world has made significant progress in the field of computer security by creating innovative and highly effective ciphers for cache encryption.

The innovative cipher,

designed by Assistant Professor Rei Ueno of the Research Institute of Electrical Communication at Tohoku University,

overcomes the threat of side-channel cache attacks, offering tremendous security and performance improvements.

Modern computer systems are under serious threat from cache side-channel attacks,

which can surreptitiously collect sensitive data such as secret keys and passwords from unsuspecting targets.

Countering these attacks is extremely difficult because they take advantage of flaws in today’s computer mechanics,

making devising an effective countermeasure extremely challenging.

Cache randomization has emerged as a promising countermeasure however, identifying a secure

and effective mathematical function for this purpose has been a lingering challenge.

To overcome this,

Ueno and his colleagues created SCARF. SCARF is based on a comprehensive mathematical formulation and modeling of cache side-channel attacks, offering robust security.

Moreover, SCARF exhibits remarkable performance, completing the randomization process with only half the latency of existing cryptographic techniques.

The cipher’s practicality and performance were thoroughly validated through rigorous hardware evaluations and system-level simulations.
