A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

Secure data parser method and system

The systems and methods of the present invention provide a solution that makes data provably secure and accessible—addressing data security at the bit level—thereby eliminating the need for multiple perimeter hardware and software technologies. Data security is incorporated or weaved directly into the data at the bit level. The systems and methods of the present invention enable enterprise communities of interest to leverage a common enterprise infrastructure. Because security is already woven into the data, this common infrastructure can be used without compromising data security and access control. In some applications, data is authenticated, encrypted, and parsed or split into multiple shares prior to being sent to multiple locations, e.g., a private or public cloud. The data is hidden while in transit to the storage location, and is inaccessible to users who do not have the correct credentials for access.

Systems and methods for securing data in motion

A secure data parser is provided that may be integrated into any suitable system for securely storing data in and communicating data with cloud computing resources. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security.

Systems and methods for securing data in the cloud

A system for performing authentication of a first user to a second user includes the ability for the first user to submit multiple instances of authentication data which are evaluated and then used to generate an overall level of confidence in the claimed identity of the first user. The individual authentication instances are evaluated based upon: the degree of match between the user provided by the first user during the authentication and the data provided by the first user during his enrollment; the inherent reliability of the authentication technique being used; the circumstances surrounding the generation of the authentication data by the first user; and the circumstances surrounding the generation of the enrollment data by the first user. This confidence level is compared with a required trust level which is based at least in part upon the requirements of the second user, and the authentication result is based upon this comparison.

Context sensitive dynamic authentication in a cryptographic system

The invention is a cryptographic server providing interoperability over multiple algorithms, keys, standards, certificate types and issuers, protocols, and the like. Another aspect of the invention is to provide a secure server, or trust engine, having server-centric keys, or in other words, storing cryptographic keys on a server. The server-centric storage of keys provides for user-independent security, portability, availability, and straightforwardness, along with a wide variety of implementation possibilities.

Cryptographic server with provisions for interoperability between cryptographic systems

The disclosed invention is a new cryptographic method which is fast and ideally suited for secure, high volume data communication and storage. The data is encrypted at the source using a private key and then transmitted to a destination over a secure or insecure channel. The destination can either be a local storage device or a non-local station. At the destination the data is decrypted using the same private key. The disclosed invention is a new method and apparatus for data encryption. The mathematical robustness and simplicity of this method brings a great improvement in security and speed as compared to previous block ciphers. The data block length or the key length can also be changed very easily and such changes do not require any significant redesigns in the components of the cipher. This is a significant advantage over previous block ciphers, where extensive modifications are needed if the key or the data block length is to be altered, if this is even feasible.
