secret-key cryptographic system
41Cramer–Shoup cryptosystem — The Cramer–Shoup system is an asymmetric key encryption algorithm, and was the first efficient scheme proven to be secure against adaptive chosen ciphertext attack using standard cryptographic assumptions. Its security is based on the… …

43Digital credential — Digital credentials are the digital equivalent of paper based credentials. Just as a paper based credential could be a passport, a Driver s license, a membership certificate or some kind of ticket to obtain some service, such as a cinema ticket… …
44Computer security compromised by hardware failure — is a branch of computer security applied to hardware. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible …

46Clipper chip — Not to be confused with Clipper architecture. The Clipper chip was a chipset that was developed and promoted by the U.S. Government[1] as an encryption device to be adopted by telecommunications companies for voice transmission. It was announced… …
47Network Security Services — Developer(s) AOL, Red Hat, Sun Microsystems, Oracle Corporation, Google and others Stable release 3.12.8 / September 23, 2010; 13 months ago (2010 09 23) …
48Deniable encryption — In cryptography and steganography, deniable encryption is encryption that allows its users to convincingly deny that the data is encrypted, or that they are able to decrypt it[citation needed]. Such convincing denials may or may not be genuine.… …
49Random number generator attack — The security of cryptographic systems depends on some secret data that is known to authorized persons but unknown and unpredictable to others. To achieve this unpredictability, some randomization is typically employed. Modern cryptographic… …
50Ciphertext — The Zimmermann Telegram (as it was sent from Washington to Mexico) encrypted as ciphertext. This article is about encrypted information. For an overview of cryptographic technology in general, see Cryptography. In cryptography, ciphertext (or… …
