TCC was an early player in the field of voice scramblers, and holds no less that 17 patents in the field of secure communications. Furthermore, the company claims to have developed 17 crypto­graphic algorithms [1]. In 1995, TCC acquired the assets of the American crypto firm Datotek from its (then) owner AT&T.
