Receptacle-Configured Cryptographic Device
First Claim
1. A cryptographic system, comprising:
- a cryptographic module that is adapted to perform encryption and decryption; and
a host platform receptacle that is adapted to receive the cryptographic module,wherein the cryptographic module has a plurality of electrically conductive pins, and is adapted to determine from an electrical state of a designated one of the plurality of electrically conductive pins whether to activate a feature provided by the cryptographic module.

Abstract
Disclosed is a cryptographic device that may automatically configure its traffic interfaces and cryptographic modes when it is inserted into an electrically keyed receptacle in a host system. Such automatic configuration may enable a single cryptographic module to support a range of input/output interfaces, such as SPI, Ethernet, RS-232 Serial, and RS-485 Serial, for example, and also to support a range of cryptographic modes, such as Cipher Block Chaining, Galois Counter Mode, or Long Cycle Mode, for Communications Security (COMSEC) and Transmission Security (TRANSEC) purposes. In addition, such automatic configuration may include parameters that affect power consumption, such as device clock rate or other power management features.

18. A host platform cryptographic module receptacle, comprising:
-
an interface for mating the receptacle with a compatible cryptographic module, the cryptographic module being adapted to execute an encryption algorithm and comprising a first plurality of electrically conductive pins; a second plurality of electrically conductive pins corresponding to the first plurality of electrically conductive pins; and electrical circuitry that sets each of the second plurality of electrically conductive pins to a respective electrical state, such that, when the cryptographic module is mated with the receptacle, the cryptographic module can determine from the electrical states of the first plurality of electrically conductive pins whether to activate associated features that the cryptographic module is adapted to provide. - View Dependent Claims (19, 20)
