President Dilma Rousseff moves the phone minister Afif Domingos (Small and Medium Enterprises), during an event in 2014
Telephone conversations recordings of President Dilma Rousseff show that information security the main institution in Brazil ranges from "fragile" and "non-existent".
For Silvio Meira, a professor of Computer Centre of the Federal University of Pernambuco, it is "inconceivable" that the leader of one of the largest countries in the world "talk to a phone that does not know who he is or to what this device is subjected."
"The weakness is total. You have a situation where the president runs the risk of being recorded by someone guarded by federal police in major criminal investigations in the history of Brazil and where there was clearly a huge potential that conversation be recorded," Meira said the BBC Brazil.
Conversations Rousseff captured by PF integrate a series of telephone intercepts of former President Luiz Inacio Lula da Silva, included in the survey Operation Lava jet. The Paraná Federal Court released the audio and transcripts last week. In the most controversial dialogue, Dilma tells Lula to send their "proper term" as new minister of the Civil House, for use "in case of need." Researchers interpreted the dialogue as an attempt by the president to avoid possible arrest of the predecessor.
For Meira, Brazil should mirror the US, where all conversations of state interest held by the president are secure (encrypted). The dialogues are not recorded, according to the expert, but the White House produces informal transcripts. "The American president speaks in secure communications, as the Prime Minister of England, France and Germany, but has no right to say whatever he wants alone . It can not, for example, connect to another and combine a nuclear attack, there is a whole state of communications protocol, a high degree of sophistication, "he says.
protection systems
Encryption is a way to enhance the security of a message or file. The technology scrambles the content so that it can only be read by those who have the encryption key called necessary to unscramble it.
Abin (Brazilian Security Agency) offers a range of equipment that can ensure the safety of communication of the president and senior officials. There are, for example, fixed telephone and application for smartphones with voice encryption and data, employing mathematical algorithm of property and exclusive use of the Brazilian state.
Asked about the reasons why the president does not use the technology offered by Abin, such as phone insurance, the Secretary of the Presidential Press just reported that "does not comment on matters that may affect the privacy or safety of the Presidency."
Sought by the report, Abin, which is the successor to the democratic period of the SNI (National Information Service) spy agency of military dictatorship (1964-1985), also declined to comment.
According to Meira to the conversation between Lula and Dilma be considered safe, both would have to have used encrypted phones or encryption applications on your smartphone. According to the Federal Court of Paraná, the bugged phone was often used by former president and belongs to an aide to Lula Institute.
Irony Snowden
The clip involving Dilma and Lula was the target of an ironic comment of Edward Snowden, a former adviser to the US National Security Agency NSA.
In 2013, Snowden released-secret documents show that the NSA had spied communications Dilma and other world leaders. At the time, the leaks caused outrage in the Brazilian government and cooled relations between the US and Brazil - Dilma arrived to cancel a state visit to Washington because of the episode.
"Going dark (staying in the dark, in translation in Portuguese) is a fairy tale. Three years after the headlines @dilmabr clips she is still making unencrypted calls," Snowden wrote on Twitter. The expression "going dark" refers to use of encryption.
Meira said that Brazil did not advance - and probably kicked - in information security since the revelations of Snowden. "Since then, for example, the email system of state agents should have changed to closed system, encrypted, remains the same. We continue sending e-mail to public officials in ministries, in very high level, using services like Gmail. "
The expert says that this is not a problem of technology, but implementation processes as resources to make secure communications are available. He cites, for example, that there are simple applications to encrypt the exchange of information (voice and data) for smartphones. "It's not a technological problem that is solved long ago. It processes, methods, compliance (internal policy) accountability. It's another problem."
National security
On the first trip after the announcement of Lula clips, last week, President Dilma criticized the interception of their conversations and stated that it is a crime against the National Security Law.
For Meira, electronic engineer from ITA, master in computer UFPE and doctor computing from the University of Kent (England), the problem is another.
"The problem that should be being discussed because of these recordings is as communications of the Presidency are as rudimentary and are subject to so few screens to point the president is talking to phone who a priori do not even know who they are ? "he asked.
