Cryptographic Techniques in Advanced Information Management

Abstract

The paper presents new solutions in the area of application cryptographic protocols for strategic or personal information protection and management. Computer techniques for classified information protection and distribution will be described in the context of application for security purposes personal or biometric information. Such techniques may also support the management processes of confidential data, and distribution of parts of shared information in large management structures. Development of presented algorithms will enable the reconstruction of secured information exclusively by the confidants with access to the secret, and parts of the information shared -i.e. by the authorized users of shared information. At the same time the proposed information division techniques will effectively secure data against unauthorized access to encrypted information.

Privacy-Preserving Schemes of Distributed Sensor Networks with Dynamic Code

“…Cryptography and information security theory are two traditional privacy-preserving approaches 5 . Multi-party computation 6 is an important technology of cryptography that solves the problem of two or more users in a mutually distrustful multi-user network.…”

Privacy‐preserving scheme of distributed sensor networks with dynamic code

“…Cryptography and information security theory are two traditional privacy-preserving approaches. 5,6 Homomorphic encryption is an important technology of cryptography. 7,8 The work 9 proposed a fully homomorphic encryption scheme with encryption depth optimization, which can simplify the re-encryption process and improve the efficiency of the fully homomorphic encryption scheme.…”

Biometric Methods for Advanced Strategic Data Sharing Protocols

“…Splitting and sharing algorithms usually divide secure data, data sets or strategic information, into n different parts or shares. The secret splitting procedures were discuses in publication [6] [7][8] [15] [16]. Secret sharing protocols were described in publication [9], [11] [14][18] [19].…”

“…The sharing protocols were dedicated to many kind of digital information [3][5] [14][15] [16]. For example: to sharing of secret data [9][13] [17], to manage information in business protocols or management processes [7][8] [10], to distribute strategic information [11], and also for homeland security purposes [6].…”
