Abstract
In today’s world of big data and rapidly increasing telecommunications, using
secure cryptographic primitives that are parallelizable and incremental is becoming ever
more important design goal. π-Cipher is parallel, incremental, nonce based authenticated
encryption cipher with associated data. It is designed with the special purpose of providing
confidentiality and integrity for big data in transit or at rest. It has, as an option, a secret
part of the nonce which provides nonce-misuse resistance. The design involves operations
of several solid cryptographic concepts such as the Encrypt-then-MAC principle, the XOR
MAC scheme and the two-pass sponge construction. It contains parameters that can provide
the functionality of tweakable block ciphers for authenticated encryption of data at rest.
The security of the cipher relies on the core permutation function based on ARX (Addition,
Rotation and XOR) operations. π-Cipher offers several security levels ranging from 96 to
256 bits.
