In cryptography, Block ciphers such as AES or DES are a symmetric key cipher operating on fixed-length groups of bits, called blocks, and typically operate on large input data blocks i.e. 64 or more than 128, 256 bits. Block cipher encrypts Plain-text to Cipher-text by applying cryptographic key and algorithm to a block of data at once as a group rather than to one bit at a time, so that identical blocks of text do not get encrypted the same way. However, some applications need smaller blocks, and possibly non-binary blocks. So, to fulfil this need Cisco is providing a small block cipher , what it calls “FNR” (Flexible Naor and Reingold), but currently it is an experimental block cipher rather a production software. Sashank Dara, software engineer at the security technology group Cisco, says in a detailed explanation that FNR is a flexible length small domain block cipher for encrypting objects that works without the need for padding, as happens in the traditional block ciphers such as AES (Advanced Encryption Standard) and DES (Data Encryption Standard). “ .” Sashank Dara said.FEATURES OF FNR Format-preserving encryption (FPE) - the length of plaintext and ciphertext remains same. FNR is flexible for large input domains that are greater than 32 bits and less than 128 bits. The encryption key length is not dependent on the input length and rather depends on underlying pseudo-random function (PRF). I have taken an example from Wikipedia to explain the importance of Format-preserving encryption (FPE): SMALL-BLOCK ENCRYPTION SECURITY? Small domain block ciphers are useful tool in designing privacy of sensitive data fields of smaller length, but smaller blocks leads to important security issues and building a secure small block cipher is known to be a tricky task. According to Cisco, FNR is an experimental small domain block cipher for encrypting objects like IPv4, Port numbers, MAC Addresses, IPv6 address and any random short strings and numbers, while preserving their input length. “Like all deterministic encryption methods, this does not provide semantic security, but determinism is needed in situations where anonymizing telemetry and log data (especially in cloud based network monitoring scenarios) is necessary,” Cisco warned. Cisco has Open Sourced the FNR encryption scheme under open source license LGPLv2 on Github. sursa:TheHackerNews

pentru inceput factory reset.Apoi incearca alt ROM (preferabil custom ROM) - vezi Omega ROm de pe XDA Edit:Omega Rom Series | OmegaDroid - Android News, Apps, Games, Devices, Guides, Development, Omega Projects, Omega Rom Series, Omega Files -

Mai bine vezi din ce cauza ai disk usage ...vezi ce procese folossc hddul aiurea. Btw...poll-ul ar trebui facut cu multi-select.Multi folosim cel putin 2 sisteme de operare Folosesc Win8.1x64 + Ubuntu 14.04 si m-ar tenta un hackintosh Mobil: Android 4.4.2 (root+mods+custom recovery)

daca e sa comparam cu pedepsele luate de berbecali,borcea si ceilalti care au fraudat de milioane de euro...a luat exagerat de mult.Ce a facut e clar o nebunie dar ''cine-i prost,sa moara" .majoritatea probabil au fost "sparte" prin social engineering.Bravo lui ca a putut face asta dar multa muie pentru ca le-a facut publice imediat, iar nu dupa ce era sigur ca e in siguranta si nu i se putea lua urma.In fond nu cred ca a publicat ceva util (vezi wikileaks) //coherence not found today -

Cea mai buna acoperire tind sa cred ca Orange o are.In ultimii 12-13 ani am avut vreo 7 Orange,iar restul cosmote.Nu folosesc abonamente pentru ca sunt enervante si nu mi-e lene sa reincarc.Au fost ok si unii si altii dar calitatea parca tinde tot spre orange.Netul de la Vodafone pare mai ok totusi -
e treaba de firmware.poti sa bagi tu si android 1.6 daca firmware ramane acelasi.Cauta pe cineva sa iti faca rescriere jtag
