Hur säkra är elektroniska signaturer ur avtalsrättslig synpunkt?
… not been altered and also to identify the sender of the information. By way of encryption information in a document is guarded from unauthorized acess. Electronic signatures are produced by using encryption technology which is devided into two groups, symmetrical and …
… compares the impact on disk performance in a GNU/Linux environmentwith three encryption algorithms: AES, Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used. The thesis shows that the …
… DES and IDEA are symmetrical algorithms and as such they use the same key for encryption and decryption. RSA on the other hand is an asymmetrical algorithm. Asymmetrical algorithms use two keys, one for encryption and the other for decryption. The factor that is most decisive …

… pressed three times, the data with the timer values will be encrypted with the encryption algorithm TEA. The data will then be sent to the receiver unit. The received data will be decrypted and compared to pre saved values to see if the data agree. To be informed of the …
… sensitive information can becompromised. A classic solution to the problem is encryption of individual files, but ithas some drawbacks as it puts a great responsibility on the users and unencryptedinformation can be left by mistake. A better solution to the problem is …
This work is about cryptography in general but also how the encryption works, and what's needed for encryption to work. I will also take up a little around the history around the encryption.
Att utnyttja volatil data i Krypterade system
When the use of encryption amongst the regular computer user grows morewidespread than ever it makes the life of the IT-forensics experts difficult.Hampering the judicial investigations that otherwise could have lead to convictions. In this report we will treat the subject of …
… important issue in wireless environment is security. Both standards use encryption to protect their messages. The difference is that HiperLAN/2 changes their encryption key for every connection where 802.11a uses the same key the whole time. This gives HiperLAN/2 a better …
En studie i säkerhetslösningar utförd på uppdrag av Saab Bofors Dynamics AB.
… the combination of standards such as IEEE802.1X and IEEE802.11i, and improved encryption with Advanced Encryption Standard (AES) it is possible to make the wireless network more secure. It is important to ensure secure wireless communication between the client and the …
Oskyddad och okontrollerad datakommunikation
… that WLANs and their security measures have weaknesses. The commonly used WEP encryption can quite easily be broken and can lure users into a false sense of security. The study shows that companies are aware of this weakness, but use the encryption be-cause it offers a good …
… populärt dataset, XMark. Kryptering genomförs med hjälp av standarden XML Encryption. Okrypterade dataset jämförs med krypterade dataset genom att ställa Xpath-frågor och mäta tiden för dessa frågeställningar. Resultaten presenteras i tabeller och grafer och analyseras utifrån …
… och VPN. Fokus ligger på hur väl krypteringsalgoritmerna Triple Data Encryption Standard (3DES) och Advanced Encryption Standard (AES) skalar i en förutbestämd miljö. Huvudfokus har varit att svara på frågan: Vilken av krypteringsalgoritmerna AES och 3DES kräver minst …
In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve …
Lösenordskryptering och Brute force attack
… 4.0 acts as the server. The project has been divided into threeparts; password encryption, Java EE authentication and brute force attack. Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash …
