Filed:

Nov 14, 2008

Appl. No.:

12/271014

Inventors:

Alexandre Gerber - Madison NJ, US

Oliver Spatscheck - Randolph NJ, US
Jennifer Yates - Morristown NJ, US
Michael Merritt - Mendham NJ, US

Assignee:

AT&T Intellectual Property I, LP - Reno NV

International Classification:

G06F 15/173

US Classification:

709238, 709239, 709240, 709242, 709243, 709244, 709249

Abstract:

A method includes receiving network distance information, receiving a request from a client for an identity of a peer providing content, and identifying a first peer and a second peer providing the content. The network distance information includes a compilation of network distance information provided by a plurality of service providers. The method further includes determining that a network distance between the first peer and the client is less than a network distance between the second peer and the client based on the network distance information, and providing the identity of the first peer to the client.

Filed:

Aug 23, 1993

Appl. No.:

8/110595

Inventors:

Steven M. Bellovin - Westfield NJ
Michael J. Merritt - Berkeley Heights NJ

Assignee:

AT&T Corp. - Murray Hill NJ

International Classification:

H04K 100

US Classification:

380 25

Abstract:

A cryptographic communication system is disclosed which permits computer users to authenticate themselves to a computer system without requiring that the computer system keep confidential the password files used to authenticate the respective user's identities. The invention is useful in that it prevents a compromised password file from being leveraged by crafty hackers to penetrate the computer system.

US Patent:

Filed:

Oct 2, 1991

Appl. No.:

7/770064

Inventors:

Steven M. Bellovin - Westfield NJ
Michael Merritt - Berkeley Heights NJ

Assignee:

AT&T Bell Laboratories - Murray Hill NJ

International Classification:

H04L 900

US Classification:

380 21

Abstract:

A cryptographic communication system. The system, which employs a novel combination of public and private key cryptography, allows two parties, who share only a relatively insecure password, to bootstrap a computationally secure cryptographic system over an insecure network. The system is secure against active and passive attacks, and has the property that the password is protected against offline "dictionary" attacks. If Alice and Bob are two parties who share the password P one embodiment of the system involves the following steps: (1) Alice generates a random public key E, encrypts it with P and sends P(E) to Bob; (2) Bob decrypts to get E, encrypts a random secret key R with E and sends E(R) to Alice; (3) Alice decrypts to get R, generates a random challenge C. sub. A and sends R(C. sub. A) to Bob; (4) Bob decrypts to get C. sub.

Appl. No.:

8/125970

Inventors:

Yehuda Afek - Berkeley Heights NJ
Michael J. Merritt - Berkeley Heights NJ
Gadi Taubenfeld - Murray Hill NJ

Assignee:

AT&T Corp. - Murray Hill NJ

International Classification:

G06F 1100

US Classification:

395575

Abstract:

Memories which have new benign failure modes. The new failure modes are the omission-crash mode and the eventual-crash mode. Memories having either of these modes fail more benignly than memories having the omission failure mode, but unlike memories having the crash failure mode, memories with the novel failure modes may be used to construct gracefully-degrading fault tolerant objects. Implementations of memories with the new failure modes are disclosed, along with implementations of fault-tolerant objects made from memories with the new failure modes.
