A practical state recovery attack on the stream cipher Sablier v1
Xiutao FENG, Fan ZHANG
Secret-key cryptography

Sablier is an authenticated encryption cipher submitted to the CAESAR competition, which is composed of the encryption Sablier v1 and the authentication \textup{Au}. In this work we present a state recovery attack against the encryption Sablier v1 with time complexity about $2^{44}$ operations and data complexity about 24 of 16-bit keywords. Our attack is practical in the workstation. It is noticed that the update of the internal state of Sablier v1 is invertible, thus our attack can further...
