Cipher For Disk Encryption
view source -
US Patent:7602906, Oct 13, 2009
-
Filed:Aug 25, 2005
-
Appl. No.:11/211865
-
Inventors:Niels Thomas Ferguson - Redmond WA, US
-
Assignee:Microsoft Corporation - Redmond WA
-
International Classification:H04L 9/00
-
US Classification:380 29, 380 42
-
Abstract:Encryption is provided with additional diffusion components to construct a block cipher with a large and variable block size. The cipher incorporates an encryption system or algorithm such that the cipher is at least as secure as the encryption system or algorithm. Additional components of the cipher provide improved diffusion. This combination ensures that the cipher is at least as strong as the encryption algorithm, and at the same time it provides additional security properties due to its improved diffusion.

-
Abstract:An access control system applies contents-based policies to data that is being transferred. This transfer can be between different computers, different operating systems on a single computer, different applications within on the same operating system, or different parts of the same operating system, for example. Data is scanned at a scan engine associated with a security reference monitor (SRM) as the data is being transmitted, on-the-fly. The data is forwarded directly to the recipient, so the data is not stored at the SRM. The data is encrypted at the SRM as it comes by, and the key is revealed to the recipient if it is subsequently determined that the transfer is allowed.

Fast Rsa Signature Verification

US Patent:7774607, Aug 10, 2010
-
Filed:Dec 18, 2006

Appl. No.:11/640796

Inventors:Niels Ferguson - Redmond WA, US
-
Assignee:Microsoft Corporation - Redmond WA
-
International Classification:H04L 9/00
-
US Classification:713176, 380 28, 380 30
-
Abstract:An RSA message signature can be verified by verifying that smod n=F(m, n). If a value K, defined as K=sdiv n is computed in advance and provided as an input to the computing device verifying the signature, the signature verification can be significantly faster. To avoid transmission of, and mathematical operations on, large values of K, which can themselves be inefficient, the RSA public exponent e can be selected to be relatively small, such as e=2 or e=3. K is based on publicly available information and can be calculated by the computing device signing the message, or by an intermediate computing device, and transmitted to the device verifying the signature without impacting security.

Abstract:An authentication mechanism is provided for a web method platform that allows homogeneous access for different types of clients according to a bootstrapping procedure utilized to establish the session. Different clients can be assigned different levels of trust based in part on the bootstrapping procedure and/or information provided during the procedure. The bootstrapping procedure can produce a token that is used by the clients in subsequent requests to provide previous authentication or state information to the platform. The token can comprise a shared secret used to ensure integrity of communications in some cases, and the token can be opaque to the client. Tokens can expire and require a client to re-bootstrap to provide higher levels of authentication protection, and tokens can be shared among a plurality of application servers to facilitate effective handling of requests in a farmed environment.

Abstract:Executable instructions designed to provide faster cryptographic processing, fixed-timing memory access, and dedicated memory usage are implementable on an x86 CPU utilizing XMM registers. The instructions can be utilized to implement cryptographic processing in accordance with the Advanced Encryption Standard (AES). To encrypt, a single instruction performs nonlinear transformation, rotation, and linear transformation. Another single instruction used during encryption performs nonlinear transformation and rotation. New instructions also are implemented to perform decryption. The instructions implemented to perform decryption perform the mathematical inverse functions of their counterparts used for encryption.

US Classification:380277, 380 44

Abstract:In an example, one or more cryptographic keys may be associated with a group. Any member of the group may use the key to encrypt and decrypt information, thereby allowing members of the group to share encrypted information. Domain controllers (DCs) maintain copies of the group's keys. The DCs may synchronize with each other, so that each DC may have a copy of the group's keys. Keys may have expiration dates, and any client connected to a DC may generate a new key when a key is nearing expiration. The various clients may create new keys at differing amounts of time before expiration on various DCs. DCs that store keys early thus may have time to propagate the newly-created keys through synchronization before other DCs are requested to store keys created by other clients. In this way, the creation of an excessive number of new keys may be avoided.

Abstract:In Transport Layer Security (TLS) or other communication protocols, the load on the server may be lowered by reducing the number of expensive decryption operations that the server has to perform. When a client contacts a server, the client sends the server the client's public key. The server chooses a secret value, encrypts the value with the client's public key, and sends the encrypted value to the client. When the client decrypts the secret, the server and client share a secret value, which may be used to derive an encryption key for further messages. In many key agreement schemes, the client chooses and encrypts the secret value, and the server recovers the value with an expensive decryption operation. By instead having the server choose the value and send it to the client, an expensive decryption operation is redistributed from the server to the client, thereby freeing server resources.
