OleF: an Inverse-Free Online Cipher. An Online SPRP with an Optimal Inverse-Free Construction

Online ciphers, in spite of being insecure against an sprp adversary, can be desirable at places because of their ease of implementation and speed. Here we propose a single-keyed inverse-free construction that achieves online sprp security with an optimal number of blockcipher calls. We also include...
