Homomorphic Encryption Makes Real-World Gains, Pushed by Google, IBM, Microsoft

eSecurity Planet

The increasing mobility of data, as it ping-pongs between clouds, data centers and the edge, has made it an easier target of cybercrime groups, which has put a premium on the encryption of that data in recent years. Since then, interest in fully homomorphic encryption (FHE) has increased, largely paralleling the rise of cloud computing.

Another Branch Prediction Attack

Schneier on Security

The researchers looked only at Intel processors, using the attacks to leak information protected using Intel's SGX (Software Guard Extensions), a feature found on certain chips to carve out small sections of encrypted code and data such that even the operating system (or virtualization software) cannot access it. Research paper.

The Doghouse: Crown Sterling

Schneier on Security

I dropped it both because it stopped being fun and because almost everyone converged on standard cryptographic libraries, which meant standard non-snake-oil cryptography. The paper was co-authored by Physicist and Number Theorist Talal Ghannam PhD. Crown Sterling is complete and utter snake oil. Sounds like complete snake-oil, right?

Researchers released a free decryption tool for the Rhysida Ransomware

Security Affairs

The experts exploited the vulnerability to reconstruct encryption keys and developed a decryptor that allows victims of the Rhysida ransomware to recover their encrypted data for free. Rhysida ransomware employed a secure random number generator to generate the encryption key and subsequently encrypt the data.

The Hacker Mind Podcast: Fuzzing Crypto

ForAllSecure

Guido Vranken returns to The Hacker Mind to discuss his CryptoFuzz tool on GitHub, as well as his experience fuzzing and finding vulnerabilities in cryptographic libraries and also within cryptocurrencies such as Ethereum. Fortunately, in this episode, we’re discussing vulnerabilities in both. Yeah, like that.
