An Australian company last week launched a security tool for GSM mobile phones that encrypts transmissions to avoid eavesdroppers. The SecureGSM application uses 256-bit, triple cipher, layered encryption based on AES, Twofish and Serpent ciphers. According to SecureGSM, all of these algorithms are considered “unbreakable” and the triple layer ensures that “encrypted data is future proof.” The product costs $188 (AU$249) for a single-user license, and each “secure” device requires a license.
