We present a practical attack on the Panama hash function that generates a collision in 26 evaluations of the state updating function. Our attack improves that of Rijmen and cowork...

Abstract. “Hash then encrypt” is an approach to message authentication, where first the message is hashed down using an ε-universal hash function, and then the resulting k-bi...
