Patent number: 7212632Abstract: A cryptographic key split combiner, which includes a number of key split generators for generating cryptographic key splits and a key split randomizer for randomizing the cryptographic key splits to produce a cryptographic key, and a process for forming cryptographic keys. Each of the key split generators generates key splits from seed data. The key split generators may include a random split generator for generating a random key split based on reference data. Other key split generators may include a token split generator for generating a token key split based on label data, a console split generator for generating a console key split based on maintenance data, and a biometric split generator for generating a biometric key split based on biometric data. All splits may further be based on static data, which may be updated, for example by modifying a prime number divisor of the static data. The label data may be read from a storage medium, and may include user authorization data.Type: GrantFiled: October 9, 2001Date of Patent: May 1, 2007Assignee: TecSec, Inc.Inventors: Edward M.

Patent number: 7178025Abstract: A method of authenticating a user to use a system includes using a provider token to generate a random value. The token generates a derived key based at least in part on a token-provided salt value and a user-provided password. The provider generates a token unlock key based at least in part on the derived key and sends it to the token. First and second challenge data instances are generated by the provider and the token, respectively, and the process is terminated if the challenge data instances are determined not to match. If the challenge data instances are determined to match, then an encrypted data transfer system is established between the token and the provider, and the token unlocks locked private data stored on the token. The user is authenticated for secured use of the system based at least in part on the unlocked private data.Type: GrantFiled: January 30, 2003Date of Patent: February 13, 2007Assignee: Tec Sec, Inc.Inventors: Edward M.

Patent number: 7131009Abstract: A method of authenticating the identity of a user to determine access to a system includes providing a plurality of factor-based data instances corresponding to a user, evaluating the factor-based data instances to determine if the user's identity is authenticated, and granting or restricting the user's access to the system if the user's identity is authenticated. More particularly, the method includes providing a modified data instance based on a second data instance, generating a key based on a first data instance, applying the key to the a modified data instance to generate a recovered data instance, interrogating the recovered data instance against the second data instance to generate an authentication value as a result of a correspondence evaluation, and granting or restricting the user's access to the system based at least in part on the validity of the authentication value.Type: GrantFiled: November 18, 2004Date of Patent: October 31, 2006Assignee: Tecsec, Inc.Inventors: Edward M.

Patent number: 7111173Abstract: A method of encrypting an object includes generating a cryptographic key, using the cryptographic key to initialize a cryptographic algorithm, and applying the algorithm to the object. Accordingly, an encrypted object is formed. The key is generated by combining key splits derived from different sources. One of the key splits is a biometric value derived from and corresponding to a particular person.Type: GrantFiled: September 1, 1999Date of Patent: September 19, 2006Assignee: Tecsec, Inc.Inventor: Edward M.

Patent number: 7089417Abstract: A method of providing cryptographic information and flow control includes first determining a target domain from an IP address. An organization policy is looked up from a credential store, and an algorithm and credentials specified for the target domain are looked up in a domain-credential map. Any further credentials that are provided and that are permitted by the organizational policy are added. A working key is then generated, and information is received in the form of a receive packet. Any packet header is stripped from the receive packet and the remaining data is encrypted. Key splits are retrieved from the credential store, and are combined to form a key-encrypting key. The working key is the encrypted with the key-encrypting key, and a CKM header is encrypted. The encrypted CKM header is concatenated to the beginning of the encrypted data to form transmit data, and the packet header and the transmit data are concatenated to form a transmit packet.Type: GrantFiled: November 18, 2003Date of Patent: August 8, 2006Assignee: TECSEC, Inc.Inventors: C.

Publication number: 20030172280Abstract: The invention uses symmetric key cryptography for secrecy. Role-based access controls are implemented with the use of labeled splits that are combined to generate the keys used in symmetric key cryptographic algorithms. Strong user authentication is realized with CKM technology in the form of user passwords, biometric data, and tokens, such as a supercard. Data separation, with labeling and algorithm selection, provides functionality comparable to physical separation. CKM technology lends itself to data-at-rest that may be defined as objects that exist for some time, such as computer files, databases, e-mail messages, etc. However, CKM is also suited for channel or pipeline transmitted data. CKM technology can be extended beyond applications into lower levels of a network protocol, e.g., in IEEE 802 protocols or at level 2 in the OSI model of networking. The CKM encryption protocol to establish the session key for the channel can be adapted to the parameters of the communications environment.Type: ApplicationFiled: October 22, 2002Publication date: September 11, 2003Inventors: Edward M.
