A method for secure computation includes receiving a specification of an input variable including one or more first elements of a quandle and an arithmetic computation to be performed over the input variable. The input variable is encrypted using a first operation of the quandle performed over the input variable together with an encoding variable including one or more non-unity second elements of the quandle. The arithmetic computation is applied to the encrypted input variable to produce an encrypted output variable. The encrypted output variable is decrypted using the encoding variable and a second operation of the quandle to obtain a result of the arithmetic computation over the variable.
