Symmetric Key and Public Key Encryption
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Recover a RSA Private Key From a TLS Session With Perfect Forward Secrecy
by Marco Ortisi They always taught us that the only thing that can be pulled out from a SSL/TLS session using strong authentication and latest Perferct Forward Secrecy ciphersuites is the public key of the certificate exchanged during the handshake - an insufficient condition to place a MiTM attack without to generate alarms on the validity of the TLS connection and certificate itself. Anyway, this is not always true. In certain circumstances it is possible to derive the private key of server regardless of the size of the used modulus. Even RSA keys of 4096 bits can be factored at the cost of a few CPU cycles and computational resources. All that needed is the generation of a faulty digital signature from server, an event that can be observed when occurring certain conditions such as CPU overheating, RAM errors or other hardware faults. Because of these premises, devices like firewall, switch, router and other embedded appliances are more exposed than traditional IT servers or clients. During the talk, the author will explain the theory behind the attack, how common the factors are that make it possible and his custom pratical implementation of the technique. At the end, a proof-of-concept, able to work both in passive mode (i.e. only by sniffing the network traffic) and in active mode (namely, by participating directly in the establishment of TLS handshakes), will be released.

IPSec Short for IP Security, a set of protocols developed by the IETF to support secure exchange of packets at the IP layer. IPsec has been deployed widely to implement Virtual Private Networks (VPNs). IPsec Encryption Modes IPsec supports two encryption modes: Transport and Tunnel. Transport mode encrypts only the data portion (payload) of each packet, but leaves the header untouched. The more secure Tunnel mode encrypts both the header and the payload. On the receiving side, an IPSec-compliant device decrypts each packet. For IPsec to work, the sending and receiving devices must share a public key. This is accomplished through a protocol known as Internet Security Association and Key Management Protocol/Oakley (ISAKMP/Oakley), which allows the receiver to obtain a public key and authenticate the sender using digital certificates.

How EFS, SSL and IPSEC Encrypt
Encryption is an important tool for security communications. In this video, Doug explores the methods used in EFS, IPSEC and SSL. Digital communications can be vulnerable to eavesdropping and interception. There are a variety of security methods that enhance confidentiality. Technologies such as the Encrypting File System (EFS), IP Security (IPSEC), and Secure Sockets Layer (SSL) use a combination of methods to help ensure your digital information is safe. Senior Technical Instructor Doug Bassett peels back the mystery and shows how a combination of symmetrical and asymmetrical encryption puts your information in a lock box. He also illustrates, using EFS, how you can share this data with multiple people and still keep it secure. If you want to learn more about protecting vital data and how to ensure proper configuration, optimization and security, we invite you to attend our Active Directory, Network Infrastructure and Applications Server classes. If you have any questions, feel free to email Doug at [email protected] We look forward to seeing you soon. www.stormwindlive.com

What is PRE-SHARED KEY? What does PRE-SHARED KEY mean? PRE-SHARED KEY meaning & explanation
What is PRE-SHARED KEY? What does PRE-SHARED KEY mean? PRE-SHARED KEY meaning - PRE-SHARED KEY definition - PRE-SHARED KEY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms. The term PSK is used in Wi-Fi encryption such as Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), where the method is called WPA-PSK or WPA2-PSK, and also in the Extensible Authentication Protocol (EAP), where it is known as EAP-PSK. In all these cases, both the wireless access points (AP) and all clients share the same key. The characteristics of this secret or key are determined by the system which uses it; some system designs require that such keys be in a particular format. It can be a password, a passphrase, or a hexadecimal string. The secret is used by all systems involved in the cryptographic processes used to secure the traffic between the systems. Crypto systems rely on one or more keys for confidentiality. One particular attack is always possible against keys, the brute force key space search attack. A sufficiently long, randomly chosen, key can resist any practical brute force attack, though not in principle if an attacker has sufficient computational power (see password strength and password cracking for more discussion). Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one end, without the knowledge of anyone at the other. There are several tools available to help one choose strong passwords, though doing so over any network connection is inherently unsafe as one cannot in general know who, if anyone, may be eavesdropping on the interaction. Choosing keys used by cryptographic algorithms is somewhat different in that any pattern whatsoever should be avoided, as any such pattern may provide an attacker with a lower effort attack than brute force search. This implies random key choice to force attackers to spend as much effort as possible; this is very difficult in principle and in practice as well. As a general rule, any software except a Cryptographically secure pseudorandom number generator should be avoided.
