Abstract: A blinding function is generated. The blinding function is applied to a random value to generate a blinded random value. The blinded random value is utilized for one or more scalar multiplications in an elliptic curve cryptographic operation.

Abstract: Methods, systems, apparatus and articles of manufacture for secure recoverable offline storage of a shared secret are provided herein. A method includes establishing a connection with a cryptographic device to access a first item of encrypted information maintained by the cryptographic device, wherein the first item of encrypted information comprises an item of cryptographic information encrypted with a first item of key information, decrypting the first item of encrypted information with a second item of key information to retrieve the item of cryptographic information, and encrypting the item of cryptographic information with a third item of key information to create a second item of encrypted information, wherein the third item of key information is associated with the cryptographic device.

Abstract: An improved turbomachinery blade retaining assembly for locking the dovetail of a radially extending blade and a spring spacer means into a dovetail slot on a rotor includes axial retention means disposed within radially extending aligned slots within the rotor blade dovetail, the spring spacer means and the dovetail slot. Radial retention means disposed between the radial interior of the blade dovetail and the dovetail slot extend through one or more slots within the axial retention means to retain the axial retention means in place within the aligned radially extending notches.

Abstract: An inlet guide vane for a turbofan engine comprises a principal airfoil portion fabricated of metal and a radially outward and rearward corner portion fabricated of a frangible material which is attached to the metal portion and completes the airfoil structure. When foreign objects are ingested into the airstream to cause the closely spaced fan blades to deform forwardly to impact against the inlet guide vane, the frangible rearward corner of the inlet guide vane is caused to break off into small pieces and pass through the system without causing any significant secondary damage, thereby leaving the principal portion of the inlet guide vane to function as a relatively efficient airfoil.
