The security problems, which are detailed in CVE-2016-2183 (for OpenSSL) and CVE-2016-6329 (for OpenVPN), impact all releases of the IBM i OS, from 6.1 to 7.3.
Heartbleed Postmortem: Time to Rethink Open Source Security? But considering the financial motivation that hackers have and the increasingly sophisticated tools at their disposal, there’s no reason to take a chance by using older, weaker cipher technology when newer and stronger ciphers like AES are readily available. Why is 3DES being removed? RSA Security wished to demonstrate that DES's key length was not enough to ensure security, so they set up the DES Challenges in 1997, offering a monetary prize. Stack Overflow for Teams is a private, secure spot for you and
What is nscf calculation in Quantum ESPRESSO? The first DES Challenge was solved in 96 days by the DESCHALL Project led by Rocke Verser in Loveland, Colorado. (SSL, you will remember, is considered weak; TLS is its replacement.).
Simply put, it’s because 3DES is not considered highly secure anymore. Computer Keyes That would require the HTTPS connection to be live for about two days, which may sound impractical (and is why the vuln garnered a relatively low security threat rating). The aim in doing this was to prove that the key size of DES was not sufficient to be secure. Although it’s officially known as the Triple Data Encryption Algorithm (3DEA The brute force attack showed that cracking DES was actually a very practical proposition. Request a FREE estimate. [2], DES was a federal standard, and the US government encouraged the use of DES for all non-classified data. In 2006, another custom hardware attack machine was designed based on FPGAs.
The boards were then fitted in six cabinets and mounted in a Sun-4/470 chassis.[5]. When is a closeable question also a “very low quality” question? While Townsend Security uses the IBM i System SSL/TLS library in its products and is thus protected via IBM’s remediation work, there are a handful of third-party software vendors that have their own implementations of OpenSSL, which requires them to fix the problem themselves. Cybersecurity Is Hot, But Don’t Overlook Physical Security In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key. Customers will need to make sure that 3DES is being removed from these special ports of OpenSSL, he says. Somehow I get the idea that the OP's idea of cryptography is based on Hollywood movies. Is it appropriate for peer-reviewer to look for possible plagiarism?
Vulnerabilities In 3DES Encryption Put It Out To Pasture In IBM i November 14, 2016 Alex Woodie IBM i customers should stop using 3DES, also known as Triple DES, ciphers due to the SWEET32 vulnerabilities that could leave sensitive information unprotected as it moves between client and server via the OpenSSL and OpenVPN protocols. With the 3DES algorithm encrypting data across an HTTPS connection, the researchers determined that an attacker executing a SWEET32-based birthday attack could retrieve the plaintext keys (in the form of HTTP cookies) by capturing about 785GB of traffic between a Web browser and a server. First, IBM is now patching the SWEET32 flaws in OpenVPN, and it’s also covering IBM i 6.1 and 6.1.1 with the patches; only IBM i versions 7.1 to 7.3 were patched in October. The reasons have largely to do with the fact that the 3DES algorithm uses 64-bit block sizes, and those block sizes are no longer deemed sufficient by the security community to keep vigilant cybercriminals at bay. But the average IBM i shop runs a lot of non-IBM code, including FTP and Telnet utilities developed by third-party vendors.
“This one is important and you should take a look at it right away,” he writes on his Data Privacy Blog.

This is why it’s critical for IBM i shops to check their software inventory and upgrade all of the vulnerable products. “It is well-known in the cryptographic community that a short block size makes a block cipher vulnerable to birthday attacks, even if there are no cryptographic attacks against the block cipher itself,” write security researchers Karthikeyan Bhargavan and Gaëtan Leurent on the website sweet32.info, which is an excellent source for information on the SWEET32 vulnerability and how hackers can pull off brute-force “birthday” style attacks that uses the laws of probability and big data to crack one-way hashing algorithms. What is the best algorithm for overriding GetHashCode? The decryption was completed on January 19, 1999. Six months later, in response to RSA Security's DES Challenge III, and in collaboration with distributed.net, the EFF used Deep Crack to decrypt another DES-encrypted message, winning another $10,000.
Per IBM’s security alert (which you should definitely read to understand mitigations and workarounds), the PTF numbers that should be applied are as followed: If you read our October 3 story about the last batch of OpenSSL patches, you will recall that IBM already issued the SI62622 and SI62623 patches. IBM issued a batch of new PTFs to address the security vulnerabilities, both of which were given a low severity rating of 3.7 on the 10-point CVSS score, largely due to high level of complexity that a successful attack would entail.

The small key space of DES, and relatively high computational costs of Triple DES resulted in its replacement by AES as a Federal standard, effective May 26, 2002. The bad news is that there’s still a lot of 3DES out there. “You need to be talking to them right away,” Townsend writes in the blog post. In July 2012, security researchers David Hulton and Moxie Marlinspike unveiled a cloud computing tool for breaking the MS-CHAPv2 protocol by recovering the protocol's DES encryption keys by brute force. Martin Hellman and Whitfield Diffie of Stanford University estimated that a machine fast enough to test that many keys in a day would have cost about $20 million in 1976, an affordable sum to national intelligence agencies such as the US National Security Agency.

How can I pair socks from a pile efficiently? Why pixels do not weight the same? To get news from IT Jungle sent to your inbox every week. When we calculate mean and variance, do we assume data are normally distributed? DES uses a 56-bit key, meaning that there are 256 possible keys under which a message can be encrypted. Baseline Data Services. If I found two $5 bills on the ground, would it be acceptable to say "$10 are on the ground"? macOS: Disconnect Wi-Fi without turning it off. The PTFs will activate newer and more secure AES ciphers in these IBM products. On November 4, IBM issued security bulletin N1021697, which discussed what to do about so-called SWEET32 security vulnerabilities in OpenSSL and OpenVPN. The entire machine was capable of testing over 90 billion keys per second.
This was the gist of a security alert sent last week by IBM, which also issued new PTFs to address the problems in its own IBM i products.
AES, by comparison, uses a 128-bit block size, which makes a big difference in preventing potentially sensitive data that could expose plaintext keys from leaking out. Are there any? [6] This advantage is mainly due to progress in integrated circuit technology. Fresche: IBM i staffing for all of your IT needs. It would take about 9 days to test every possible key at that rate.

Deep Crack was designed by Cryptography Research, Inc., Advanced Wireless Technologies, and the EFF. In 1998, the EFF built Deep Crack (named in reference to IBM's Deep Blue chess computer) for less than $250,000. It’s supported in the IBM i stack. IBM i customers should stop using 3DES, also known as Triple DES, ciphers due to the SWEET32 vulnerabilities that could leave sensitive information unprotected as it moves between client and server via the OpenSSL and OpenVPN protocols. Big O, how do you calculate/approximate it? This is exactly 72,057,594,037,927,936, or approximately 72 quadrillion possible keys.
