Malicious MEV attacks pose a significant threat to traders on Ethereum. Our latest research shows that almost 2,000 sandwich ...

Block ciphers, a branch of modern cryptography, are playing a more prominent role in protecting information security as 5G technology develops. Although encryption algorithms of the traditional ...

Two popular AES libraries, aes-js and pyaes, “helpfully” provide a default IV in their AES-CTR API, leading to a large number of key/IV reuse bugs. These bugs potentially affect thousands of ...

Tens of millions of Internet users will be cut off from encrypted webpages in the coming months unless sites are permitted to continue using SHA1, a cryptographic hashing function that’s being retired ...

Zero-correlation linear cryptanalysis is an important method for analyzing the security of block ciphers. But there are few works on zero-correlation linear attacks combined with a related-key setting ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...
