Data encryption key failure monitor

Abstract: An encryption key, required to encrypt and decrypt data according to a predefined algorithm is usually retained in a volatile memory device Detection of loss of the key or corruption of the key is frequently possible only be means of the encryption circuit itself testing the key Automated and repetitive testing of encryption keys by means of a processor or a control circuit periodically requesting the encryption circuit to test an encryption key minimizes data loss and system down time due to corrupted or lost keys

Performance Study on Image Encryption Schemes

Abstract: Image applications have been increasing in recent years. Encryption is used to provide the security needed for image applications. In this paper, we classify various image encryption schemes and analyze them with respect to various parameters like tunability, visual degradation, compression friendliness, format compliance, encryption ratio, speed, and cryptographic security.

Large scale quantum cryptographic key distribution network

Abstract: A space-based satellite device obtains one or more encryption key symbols. The satellite device transmits the one or more encryption key symbols to multiple nodes of a land-based network using quantum cryptographic mechanisms.

An RSA family of trap-door permutations with a common domain and its applications

Abstract: Bellare, Boldyreva, Desai, and Pointcheval [1] recently proposed a new security requirement of the encryption schemes called “key-privacy.” It asks that the encryption provide (in addition to privacy of the data being encrypted) privacy of the key under which the encryption was performed. Incidentally, Rivest, Shamir, and Tauman [2] recently proposed the notion of ring signature, which allows a member of an ad hoc collection of users S to prove that a message is authenticated by a member of S without revealing which member actually produced the signature.

Portable Electronic Storage Devices with Hardware Security Based on Advanced Encryption Standard

Abstract: Portable electronic storage devices with hardware based security are described. According to one exemplary embodiment of the present invention, a portable electronic storage device (PESD) comprises a security engine integrated thereon. The security engine is configured to provide data encryption, data decryption, and encryption/decryption key (referred to as a key) generation according to a security standard (e.g., Advance Encryption Standard (AES)). AES is a symmetric encryption algorithm processing data in block of 128 bits. Under the influence of a key, a 128-bit data block is encrypted by transforming the data block in a unique way into a new data block of the same size. AES is symmetric sine the same key is used for encryption and the reverse transformation (i.e., decryption). The only secret necessary to keep for security is the key. AES may use different key-lengths (i.e., 128-bit, 192-bits and 256-bits).
