RA
Registration Authority
RAIC
Restricted Area Identity Card
RAM
Random Access Memory.
RAND
Random Number.
RATP
Reliable Asynchronous Transfer Protocol
RBS
Royal Bank Scotland
Reading Device
Device which can read and, as the case may be, manipulate information stored on a smart card.
Red Book:
See Trusted Network Interpretation.
Regulation E
A U.S. Federal regulation designed to protect users and issuers using electronic financial transfers from fraudulent transactions. It requires users to receive a receipt of financial transactions, puts restrictions on issuance of accessible devices, establishes the conditions of this type of service, and puts limits on consumer liability.
Relative Path
The location of a file relative to the current file.
Retention Time
The length of time a smart card will hold data in its nonvolatile memory—typically, 10 years
RF - Radio Frequency
An electronic wave
RF/DC
radio frequency/direct communication.
A method of communication without physical contact using radio frequency transmission
RFC
Radio Frequency Card. A proximity card in which the coupling between the card and the interface device is by radio.
RFID
Radio Frequency Identification Division. The transmission method used for A technology to identify persons, animals and goods via radio frequencies.
RISC
Reduced Instruction Set Computer
Risk Assessment:
A study of vulnerabilities, threats, likelihood, loss or impact, and theoretical effectiveness of security measures. The process of evaluating threats and vulnerabilities, known and postulated, to determine expected loss and establish the degree of acceptability to system operations
Risk Management:
The total process to identify, control, and minimize the impact of uncertain events. The objective of the risk management program is to reduce risk and obtain and maintain DAA (Designated Approving Authority) approval.
RMI
Remote Method Invocation. Technology integrated in the latest JavaCard Forum specifications (2.2 version, early 2002) used to allow a smart card to use distant resources (other smart card, reader or PC) in a piece of equipment in a transparent manner via a network (Bluetooth type, for instance). A way of bypass the card's specific controls (APDU) to have communicate with terminals.
RMV
Rhein-Main-Verkehrsverbund
RNG
Random Number Generator
Roaming
An arrangement whereby a mobile handset is be recognized by networks other than that of the issuer (notably for subscribers traveling abroad). See GSM.
ROI
RDMA (Remote Direct Memory Access) Over Internet OR
RAM Optical Instrumentation
ROM
Read Only Memory. ROM contents cannot be changed.
Router:
An interconnection device that is similar to a bridge but serves packets or frames containing certain protocols. Routers link LANs at the network layer.
RSA
Rivest-Shamir-Adleman Public key encryption algorithm. The most famous and popular public key encryption systems (using a private key and a public key). Developed by Rivest, Shamir and Adleman in 1977, it is based on the mathematical difficulty of factorising great numbers into two or several prime numbers. It is used to produce digital signatures or cipher messages.
RST
The contact or pad on the smart card module that, when activated, causes a physical reset of the microprocessor in the smart card.
RTD
Record Type Definition
Rules Based Detection:
The intrusion detection system detects intrusions by looking for activity that corresponds to known intrusion techniques (signatures) or system vulnerabilities. Also known as Misuse Detection.
