40-bit encryption - Wikipedia, the free encyclopedia 40-bit encryption is a key size for symmetric encryption representing where the key is forty bits in length (five bytes); this represents a relatively low level of security. In the light of this, it is difficult to recommend 40-bit encryption for any serious cryptographic use given the ability of today's computers to defeat it. It should also be noted that asymmetric encryption requires keys far longer than 128 bits; see that article, and key size, for more details. www.wikipedia.org /wiki/40-bit_encryption   (431 words)

Wired Equivalent Privacy - Wikipedia, the free encyclopedia Standard 64-bit WEP uses a 40 bit key, to which a 24-bit initialisation vector (IV) is concatenated to form the RC4 traffic key. WEP uses the stream cipher RC4 for confidentiality and the CRC-32 checksum for integrity. At the time that the original WEP standard was being drafted, US Government export restrictions on cryptographic technology limited the keysize. en.wikipedia.org /wiki/WEP   (752 words)

Content-scrambling system - Wikipedia, the free encyclopedia It uses a weak, proprietary 40-bit encryption stream cipher algorithm. Content-Scrambling System (CSS) is an encryption system used on some DVDs. The CSS key sets are licensed to manufactors who incorporate them into products such as DVD drives, DVD players and DVD movie releases. en.wikipedia.org /wiki/Content-scrambling_system   (266 words)

Transport Layer Security - Wikipedia, the free encyclopedia Adds Advanced Encryption Standard (AES) ciphersuites to the previously existing symmetric ciphers. In these cases, a user may wish to use standalone SSL products like Stunnel to provide encryption. However, the Internet Engineering Task Force recommended in 1997 that application protocols offer a way to upgrade to TLS from a plaintext connection, rather than use a separate port for encrypted communications - this prevents use of wrappers such as Stunnel. en.wikipedia.org /wiki/Secure_Sockets_Layer   (1255 words)

Privacy and Security on the Internet The maximum key length is 4096 bits, which should be sufficient for protecting information for the forseeable future. Encryption is a mathematical process of "scrambling" a message or a file in a way that can be reversed only with a specific password. Efforts by governments to limit civilian use of encryption technology generally have met with skepticism: questions about trustworthiness of the governments themselves may protect this important tool for ensuring the confidentiality of what patients tell their health care providers [Mitchell97]. www.cardiothink.com /ACC99/internet-security.html   (9393 words)

How hard is it to decode the encryption protecting my personal information? Most versions have 40-bit encryption by default, particularly if they were downloaded. SSL-based encryption comes in two sizes: the 40-bit ("low" or "weak") or 128-bit ("high" or "strong") level. Microsoft offer free 128-bit encryption versions of their browsers for download. www.aibn.com /help/Advisories/decode.html   (279 words)

Microsoft Host Integration Server 2000 - Data Encryption Data Encryption is RC4 40-bit encryption that secures traffic between the client computer and Host Integration Server 2000 on a per-user basis. Data encryption is enabled for Distributed Link Service by adding the domain user account under which Host Integration Server 2000 services such as SnaBase or SnaServer are running to the SNA subdomain. Data encryption is also supported in the distributed deployment of SNA Open Gateway Architecture (SOGA), which uses Host Integration Server 2000 to provide secure server-to-server communications across the Internet, intranets, and other WANs. www.microsoft.com /resources/documentation/host/2000/all/proddocs/en-us/netint/sec_data_encryption.mspx   (461 words)

Digital Home One normally measures the strength of encryption in terms of "key" length - the number of bits in the key used to encrypt or decrypt a message. Based on the past history of improvements in computer performance, security experts expect that 128-bit encryption will work well on the Internet for at least the next ten years. Encryption works by altering the original data so that it can only be recovered through a corresponding decryption process. www.intel.com /personal/digital_home/home.htm   (1533 words)

128-bit Encryption and Website Security In terms of what the numbers represent, "128" and "40" bit encryption refer to the size of the key used to encrypt the message. The main difference is that 128-bit encryption provides a significantly greater amount of cryptographic protection than 40-bit encryption. Presently, 40-bit encryption is not considered "strong" security in the cryptographic community. www.monsteradcompany.com /ordering/secure.html   (393 words)

Feds Relax Encryption Rules By merely upping the strength of the exportable software from 40 to 56 bits, the government has hardly changed course, said Zimmermann. Currently, the institute is reviewing submissions for algorithms that will form the Advanced Encryption Standard, a new cryptographic cipher that will replace the aging DES as the basis for all secure, non-classified government communications. Encryption software vendors are singing a much different tune. www.efc.ca /pages/media/wired-news.16sep98a.html   (599 words)

40-bit crypto proves no problem CNET News.com There is no limit on the strength of encryption used domestically, but newly revised U.S. export regulations have set a provisional limit of 56-bit algorithms as long as the exporter agrees to support a system of key storage that allows the government access to encrypted data. His ease in completing the hack adds fuel to the argument that 40-bit crypto, where scrambling codes are composed of a string of 40 digits, is too weak for commercial use. In that case, Netscape programmers had failed to select completely random bits for their encryption algorithms. www.news.com /News/Item/0,4,7483,00.html   (636 words)

Terrorists' code of honour The files were only encoded using 40-bit encryption, which was broken by brute force - trying all possible keys. However, most encryption experts were pretty sure that once strong encryption was available in the US, criminals and terrorists elsewhere would be able to get hold of it, legally or otherwise, and so the export ban would be pointless.

Skyline and 40-bit vs 64-bit WEP Encryption Farallon and other manufacturers have used the phrase "40-bit" to describe the WEP encryption supported by the PN473 Skyline Wireless PC Card, while others have refered to the same level of encryption as "64-bit," resulting in confusion as to which products are compatible. Thus "40-bit" describes the length of the user-supplied key, while "64-bit" describes the whole binary number used for encryption, but both terms describe the same level of security and are compatible with each other. The standard WEP encryption accepts a five-byte sequence from the user and combines it with three bytes from the 802.11b header for a total of eight bytes or 64 bits. www.proxim.com /support/all/skyline/technotes/tn2001-08-03.html   (156 words)

S/MIME Cracking Screensaver Like all algorithms that use 40 bit keys, RC2/40 is considered by many to be weak encryption. If the sending agent decides that weak encryption is unacceptable for this data, then the sending agent MUST NOT use a weak algorithm such as RC2/40. A sending agent that is controlled by a human SHOULD allow a human sender to determine the risks of sending data using RC2/40 or a similarly weak encryption algorithm before sending the data, and possibly allow the human to use a stronger encryption method such as tripleDES. www.counterpane.com /smime.html   (508 words)
