| 20100254534 | METHOD AND APPARATUS FOR ESTABLISHING A KEY AGREEMENT PROTOCOL - A system and method for generating a secret key to facilitate secure communications between users. A first and second and a function between the two monoids are selected, the function being a monoid homomorphism. A group and a group action of the group on the first monoid is selected. Each user is assigned a submonoid of the first monoid so that these submonoids satisfy a special symmetry property determined by the function, a structure of the first and second monoids, and the action of the group. A multiplication of an element in the second monoid and an element in the first monoid is obtained by combining the group action and the monoid homomorphism. First and second users choose private keys which are sequences of elements in their respective submonoids. A first result is obtained by multiplying an identity element by the first element of the sequence in a respective submonoid. Starting with the first result, each element of the user's private key may be iteratively multiplied by the previous result to produce a public key. Public keys are exchanged between first and second users. Each user's private key may be iteratively multiplied by the other user's public key to produce a secret key. Secure communication may then occur between the first and second user using the secret key. | 10-07-2010 |

| 20120074067 | METHOD OF HERDING AND COLLECTION OF OIL SPILLED AT THE AQUATIC SURFACE - Disclosed are methods of removing oil from an aqueous surface, comprising: surrounding an oil spot on the aqueous surface with an oil-absorbing material; and introducing a solution comprising a surfactant to the oil spot. Also disclosed are the above methods where the oil is not mechanically directed towards the oil-absorbing material, or where the oil-absorbing material is not mechanically directed towards the oil. Also disclosed are the above methods further comprising introducing a solution comprising a protein/surfactant complex to the oil spot, where the protein/surfactant complex comprises a protein component obtained from the fermentation of yeast, comprising a mixture of multiple intracellular proteins, at least a portion of the mixture including yeast polypeptides obtained from fermenting yeast and yeast stress proteins resulting from subjecting a mixture obtained from the yeast fermentation to stress. | 03-29-2012 |
