Patent
Method and system for multimedia access control enablement
Bernard J. Halter,Alphonse M. Bracco,Donald B. Johnson,An V. Le,Stephen M. Matyas,Rostislaw Prymak,James D. Randall,John D. Wilkins +7 more
TL;DR: In this article, a method and system are disclosed for securely distributing a plurality of software files from a software distribution processor to a user processor, while selectively enabling the user processor to only use a subset of a lesser plurality of the software files.
Patent
Network security system and method using a parallel finite state machine adaptive active monitor and responder
Paul C. Hershey,Donald B. Johnson,An V. Le,Stephen M. Matyas,John G. Waclawsky,John D. Wilkins +5 more
TL;DR: In this paper, a system and method provide a security agent, consisting of a monitor and a responder, that respond to a detected security event in a data communications network, by producing and transmitting a security alert message to a network security manager.
Patent
Authentication system using one-time passwords
TL;DR: In this paper, a system for authenticating a user located at a requesting node to a resource such as a host application located at an authenticating node using one-time passwords that change pseudorandomly with each request for authentication is presented.
Patent
Hybrid public key algorithm/data encryption algorithm key distribution method based on control vectors
Stephen M. Matyas,Donald B. Johnson,An V. Le,William C Martin,Rostislaw Prymak,William S Rohland,John D. Wilkins +6 more
TL;DR: In this paper, the authors describe a method and apparatus for securely distributing an initial Data Encryption Algorithm (DEA) key-encrypting key by encrypting a key record (consisting of the key encryption key and control information associated with it) using a public key algorithm and a private key belonging to the intended recipient.
Patent
Public key cryptosystem key management based on control vectors
Stephen M. Matyas,Donald B. Johnson,An V. Le,Rostislaw Prymak,William C Martin,William S Rohland,John D. Wilkins +6 more
TL;DR: In this article, a data processing system, method and program are disclosed, for managing a public key cryptographic system, which includes the steps of generating a first public key and a first private key as a first pair in the data process system, for use with a first key algorithm and further generating a second public key, and a second private key, as a second pair, for using with a second key algorithm, and encrypting the private key record under a first master key expression which is a function of the private control vector.
