  • Programmable telecommunications security module for key encryption adaptable for tokenless use
    Patent number: 6151677
    Abstract: A security module that is preferably tokenless and is used in telephone communications (e.g., cellular) to secure a transmitted bit stream. The module provides traffic encryption, key exchange, key protection, and algorithm protection. The module provides encryption and key processing using a programmable information security architecture (PISA). Preferably, the module does not use a physical device, such as a key or a card, to unlock the security features, and preferably, the security features all reside within the security module and not on a physical device, such as a key or a card. Instead, a personal identification number (PIN) is used to unlock the security features.
